(Prof. X. Maldague, U. Laval + TORNGATS)Corrosion under insulation (CUI) is one of the major concerns of oil and petrochemical installations as damage evolves invisibly under insulation layers and usually revealed on the occurrence of leaking or more catastrophic failure. Methods to early detect CUI and its causes is an urgent necessity to assure safety and performance of insulated process piping. Oil and petrochemical plants are often considered explosive environments in which thermal excitation devices are forbidden. The present work aims then on the consolidation of a passive thermographic methodology to reliably detect moisture trapped under insulation layers that will cause corrosion.
The proposed methodology focuses on the thermal behaviour of the piping structure during process variations and interactions with the external ambient. The partial least-squares analysis showed promising performance on separating different physical phenomena and creating cleaner images for defect detection.
Keywords: Multivariate thermography, Passive thermography, Humidity detection, CUI detection.

mass-manufacturing production using advanced ultrasonic real-time quality
monitoring feedback technology based on high speed deep learning neural network
algorithms
In this presentation we will discuss some
successful results of the real-time automated spot weld quality analysis from an
ultrasonic B-scan using deep learning. This is
the first work in this direction, where deep learning-based
framework for ultrasonic in-line detection of objects of weld shape from
ultrasonic b-scans is applied. Applying a deep learning algorithm allow us to
classify welds as good, acceptable, or bad in real-time during welding process.
As a result, this solution allows NDE specialists to improve existing automated
systems including int the process the feedback option and to produce high weld
quality classification accuracy that matches with production-level
satisfaction.
Additionally, there is another important aspect of
this problem, to demonstrate how the results obtained from deep learning model
can be interpreted to understand the physical phenomena taking place inside
materials during welding. It is crucial for manufacturing cycle times that this
understanding is achieved in real time.
In that case, high speed original algorithms allow us to make immediate
decisions and send an in-line request to the welder to modify the welding
parameters to be sure that at the end of each spot welding cycle the quality of
each weld will be a good weld, which is
a great example of advance NDE 4.0 solution.
We are confident when the whole complex of various
aspects of this problem will be resolved and demonstrate persistent results, it
will completely revolutionize the mass-manufacturing process using artificial
intelligence NDE 4.0 process at the automotive assembly plants
globally.
This technology will bring big savings in production cycle time, reduce labor
costs and eliminate unnecessary destructive tests, which are still part of
today?s quality inspection process. Target of our research is to achieve, based
on ultrasonic real-time quality monitoring feedback technology, the ambitious
target ? ?zero-defective? massive production.

We examined the effect of different metal filters on the CT scan of an unconventional object, a golf club, Taylor Made R1 driver. Four materials were chosen for evaluation (Al, Ag, Cu and Sn). The required filter thickness was determined based on the settings, penetration factor and ability of the material to remove low energy part of the x-ray spectrum. CT scans were collected on an XTH225ST scanner from X-Tek with the multi-target static 225kV reflection head and 225kV rotating head, reconstructed using CT Pro 3D from Nikon and analysed with VG Studio Max 3.0. The results show that filter materials have large impact on the x-ray spectrum and image quality and may lower or increase the scanning parameters and times.X-ray computed tomography (CT) is a powerful non-destructive tool for inspection of inner structure of materials. The ability to generate 2D and 3D models of the specimen without physically slicing (damaging) it has made CT technology highly used in industry, research and medical fields. However, generating high quality models is still challenging for specimens of complex structure due to artifacts, scattering and noise level, caused by differences in material thickness and density.

The failure of conductors coupling sleeves has brought the need for internal inspection to better understand the nature and evolution of defects. Samples are tested on conductor fatigue testing bench and brought to the laboratory for inspection. The nature, position and geometry of braid failure can be described. For some cases, the shape of a pinch defect has been described. Corrosion can also be investigated. These types of defects are altered or even destroyed during sleeve disassembly. Therefore, 3D X-ray CT scan is a very well non-destructive inspection tool to bring crucial information about failure processes.
CT scanning has proven its usefulness in many applications. The possibility to describe location of defects in 3D, fractures plane description and pre-failure detection improved knowledge on the braid failure process. Moreover, it also allows simulation of radiographies using MIP projection which can be used in protocol optimisation of 2D X-ray inspection.INRS (Institut National de la Recherche Scientifique) University and its multidisciplinary CT scan laboratory for non-medical use, located in Quebec City, has built knowledge around CT scanning imaging and image processing for more than a decade. The main two topics of study are physical modeling of sediment dynamic and lake-core investigation for paleoclimatology evaluation. As the CT scanner is within an industrial environment (sliding gantry configuration, overhead crane, large water drain and heavy duty specimen table), it makes it a highly versatile tool for a variety of static and dynamic applications. This presentation will describe the laboratory capacity and some specific case study of particular interest.

This paper presents the advanced solution Nucleom has developed to determine PP joints penetration, which consists in a semi automated Phased Array UT (PAUT) technique that was performed on orthotropic decks and structural boxes welding.For partial penetration (PP) joints, several methods have been developed to estimate the depth of weld penetration as accurately as possible. Since it is not directly visible, most of methods were based on indirect measurements using the geometrical parameters of the weld pool, temperature field, oscillation frequency etc. Various techniques were used such as vision, conventional ultrasonic testing (CUT), acoustic emission, thermal examination and macroscopic examination. The macro etch testing is the most accurate method to check the weld penetration however it is a destructive method that involves cutting a sample from the welded joint therefore could not be an alternative for postproduction inspection.

Hydro-Québec est un pionnier dans le développement de systèmes robotiques visant à inspecter et à maintenir ses actifs stratégiques tels que les barrages, les turbines, les lignes électriques et les postes de transformation. Les divisions d'affaires d'Hydro-Québec ont été parmi les premiers utilisateurs de ces technologies qui sont intégrées dans leurs pratiques de maintenance depuis plusieurs années. Avec les retombées importantes déjà captées grâce aux données recueillies au cours des inspections effectuées au cours des 15 dernières années, la robotique contribue à la gestion intelligente des actifs grâce à l'introduction de sondes d'inspection non destructive qui fournissent des données stratégiques qui n'étaient jusqu’à présent pas disponibles pour les gestionnaires d'actifs, et ce sans nécessiter des campagnes d'échantillonnage à grande échelle.
Cette présentation traitera de la structure et de la portée des travaux de l’unité Robotique d’inspection et de maintenance de l'Institut de recherche d'Hydro-Québec (IREQ). Sa mission est de fournir des solutions d'innovation technologique pour faire face aux défis des divisions d’affaires d'Hydro-Québec en matière de production, de transport et de distribution d'électricité. Avec des actifs hautement spécialisés viennent des solutions d'inspection hautement spécialisées. Développer des dispositifs robotiques mobiles capable de fonctionner dans ces environnements contraignants est un défi d’ampleur, mais l’information obtenue en retour est inestimable.
La présentation proposée portera sur les technologies de contrôle non destructif (CND) et les systèmes de déploiement robotique développés par l'Institut de recherche d'Hydro-Québec, en se concentrant principalement sur la robotique appliquée aux lignes aériennes de transport. Des robots suspendus au conducteur, tel que LineScout, les drones et d’autres plates-formes robotiques télé-opérées seront présentées. Les capteurs CND, les outils d’intervention et les processus associés à ces plates-formes robotiques seront également discutés car ils sont au cœur de la chaîne de valeur lorsqu'il s'agit de prendre des décisions optimales en matière de maintenance et de plans d’investissements.Hydro-Quebec is a pioneer in the development of robotic systems for the inspection and maintenance of its strategic assets such as dams, turbines, power lines and substations. Hydro-Quebec’s business divisions are early adopters of these technologies, which were incorporated into their maintenance practices years ago. With significant benefits already resulting from the data gathered during challenging inspections performed over the last 15 years, the contribution of robotics in smart asset management is furthered with the introduction of Non-Destructive Evaluation (NDE) probes that provide data previously not available to asset managers, without requiring large-scale sampling.
This presentation will discuss the structure and scope of work of the Inspection and Maintenance Robotics Department of Hydro-Quebec’s Research Institute. Its mission is to provide technological and innovative solutions to cope with Hydro-Quebec’s business divisions challenges in electric power generation, transmission and distribution. With highly specialized assets comes a need for highly specialized inspection solutions. Developing mobile robotic devices to operate in these highly unstructured and challenging environments is complex, but the payback is priceless.
The proposed presentation will address NDE technologies and robotic delivery systems developed by Hydro-Quebec’s Research Institute, focusing mainly on Power Line Robotics. Line-suspended robots, such as LineScout, drones and other tele-operated robotic platforms will be presented. NDE sensors, tools and processes associated with these robotic platforms will also be discussed, as they are at the heart of the value chain when it comes to making optimal maintenance decisions and capital spending plans.

Conventional PEC signal analysis has known limitations: defects smaller than the sensing area of a PEC probe are typically undersized. Also, conventional PEC techniques cannot be applied reliably in the critical pipe regions surrounding flanges, joints, supports, nozzles, valves, etc. Unfortunately, on insulated pipes and tubes, corrosion is often found near flanges, joints and valves where insulation waterproofing is more difficult. The mass effect associated to these metallic elements is well known to affect the PEC signals and to impair the detection of defects.
In this communication, we will present the latest advances in the modeling and analysis of the PEC signal, showing improvements in repeatability and accuracy. In particular, we present a novel PEC signal analysis algorithm that largely improves the sizing of small defects. A further improvement of the same technique extends the applicability of PEC to CUI/CUI inspection of pipe regions surrounding flanges and other metallic masses. Laboratory results of tests conducted on carbon steel reference specimens are presented. The performance of these improved PEC analysis techniques is compared to prior art technology, and key benefits are discussed.Pulsed Eddy Current (PEC) has been successfully deployed over the last decades for a variety of corrosion-related applications, most notably for Corrosion Under Insulation (CUI) inspections, Corrosion Under Fireproofing (CUF) and Flow Accelerated Corrosion (FAC). This technology has proven to be an efficient screening tool, allowing for detection of corrosion without having to remove coating or insulating material over typical pipes and tanks.

The proposed paper will present NDT technologies and robotics delivery systems developed by Hydro-Quebec’s Research Institute Power Line Robotics Program. The R&D efforts addressed two important degradation mechanisms affecting overhead line conductors: corrosion and weakened components.
Two complementary approaches were chosen as for corrosion detection: zinc layer remaining thickness, for ACSR steel core, is estimated with an Eddy-Current approach, and remaining steel cross sectional area, based on the Magnetic-Flux approach. Both NDT systems were successfully tested and proved to have great potential in a near future. These methods are semi-quantitative and improvement areas are identified to get a deterioration index representing the real condition of a span without the need to take a sample.
Detection of localized internal damage such as broken wires in a suspension clamp or internal corrosion/melting in a joint are important to avoid a conductor rupture during upset weather events. Very compact X-ray unit were integrated in a delivery system and tested on the network. Retrieved samples indicate a good agreement between detected inner layer broken strands underneath a suspension clamp or internal damage of a compression joint.
The value to determine the real condition inside of a component without the need to take a sample if of great value for planning remedial actions or to assess a great number of similar component in an effective and noninvasive manner. Some field results will be presented to illustrate the benefit to equip robots with NDT sensors to monitor the condition of critical spans such as river crossing, and its value for preventive maintenance and life cycle management.
La présentation portera sur les technologies CND et la robotique de service développé par l’institut de recherche d’Hydro-Québec dans le cadre de son projet en Robotique de ligne. Les efforts de R&D se sont concentrés sur 2 mécanismes de dégradation important pour les lignes de transport électrique: corrosion et affaiblissement des composants.
En ce qui concerne la corrosion, 2 approches complémentaires ont été choisies : l’évaluation de l’état de la couche de zinc par la méthode des courants de Foucault, et le flux magnétique pour mesurer la section des brins d’acier. Les 2 méthodes ont été testées avec succès et ont montré un bon potentiel pour le futur. Ces méthodes sont toutefois semi-quantitatives et des améliorations sont requises pour calculer un index représentatif de la condition sans devoir faire de prélèvements.
La détection des dommages internes comme les brins brisés dans les pinces de suspension ou la corrosion/dommage thermique dans les manchons sont importants à détecter afin d’éviter une rupture en service lors d’évènements climatiques extrêmes. Un système très compact à rayon X a été intégré et tester sur le réseau. Des échantillons prélevés ont démontré un bon accord entre la radiographie et l’état interne des composants.
L’évaluation de la condition interne des composants sans avoir à faire des prélèvements à une valeur inestimable pour planifier les interventions ou pour inspecter un grand nombre de composants d’une manière efficiente et non invasive. Quelques résultats seront présentés afin d’illustrer le bénéfice d’équiper la robotique de capteurs CND pour l’évaluation de la condition de tronçons stratégique comme les traversées de rivières, la maintenance préventive et la gestion du cycle de vie.Abstract:

This paper presents the innovation related to the full volumetric inspection of axially and circumferentially oriented flaws in a 304-stainless steel 20 feet, 18in diameter, 3/8in 1/2in thick conduit with several tight 1D and 1.5D bends. The application of eddy current arrays, phased-array UT and TOFD in a hazardous radioactive environment has proven effective at detecting and accurately characterizing trans-granular stress corrosion cracking. The inspection solution was deployed by a highly-sophisticated robotic assembly capable of navigating in the component. Technique qualification involved testing on full scale mockups with simulated TGSCC and was proven successful at detecting and characterizing flaws in all orientations.Each non-destructive evaluation method has limitations that are specific to the applicable techniques and procedures. Combining multiple methods for a given inspection challenge can provide significant advantages in terms of quality of results and site deployment efficiencies.

requires a lot of efforts to ensure accuracy and quality of product assembly. Resistance spot welding is a major means of joining metal sheets together. It is well automated, fast and reliable. At the same time, with introduction of new metals and coatings,
quality of weld joints sometimes suffers unpredictable variations. Institute for Diagnostic Imaging Research and Tessonics have developed two ultrasonic technologies for spot weld quality inspection. One approach, having a probe inside a welding electrode,
allows to scan a weld as it is being made. The other technology uses matrix array to generate a C-scan image of a weld after its production. Both systems are capable of being automated which makes them very promising for completely automating quality monitoring

Estimating the rate and mode of corrosion and deterioration in concrete structures and pipelines/ductwork containing process fluids/gases can be very complex when based only on analyses of chemical composition and environmental conditions. Prevention and protection methods are only as effective as the data they are based on. Therefore, ongoing monitoring and non-destructive testing techniques are necessary components of maintenance and corrosion management strategies to ensure the applied protection methods are effective and can be adjusted as required to mitigate damage and maintenance costs.
Case studies will be used in this paper to illustrate the use of various non-destructive testing and corrosion protection on the industrial structures. The case studies include the use of ground penetrating radar (GPR) and impact-echo for the evaluation of deteriorated reinforced-concrete structures and the use of ultrasonic testing, thermal imaging, and field coupon testing to determine the rate and mode of corrosion in process piping/ducting used for transporting aggressive process gases and fluids.Industrial structures and systems undergo chemical attack, corrosion, weathering and thermal damage which often cause the structures to deteriorate faster than normal rate. A cost effective way of extending the life of a structure is to perform non-destructive testing to identify the degree and type of damages, and then repair or apply corrosion protection to the areas that require maintenance.

The evaluation of the static modulus is expensive and time consuming as it requires destructive tests. On the other hand, dynamic testing is quicker and cheaper because it is non-destructive. The static test requires the laboratory measurement of the stress-strain curve. Conversely, the dynamic modulus is measured nondestructively at low strain test (less than 10-6); and it can be measured in-situ with portable and simple equipment.
This study investigates the relationship between the static and the dynamic moduli using resonant frequency and destructive testing measurements. The dynamic measurements follow the impact resonance method of the ASTM. We use the theoretical ratio between transversal and longitudinal resonant frequencies of concrete cylinders to automatically identify from the measured Fourier spectra the actual longitudinal resonant frequency of the specimen. Following this procedure, we propose an experimental equation that relates the static and dynamic moduli with an accuracy of approximately 10% for a random sample of 32 specimens with different aggregate sizes (e.g. 10mm to 20mm) and different ages (e.g. 0.3 to 2 years) of concrete (random mix).The static modulus is typically measured from the slope of the stress-strain curve using a strain range between 10-4 and 10-3. Whereas, the dynamic elastic modulus is computed from wave velocity or resonant frequency measurements. This paper presents the results of an experimental program designed to measure the static and dynamic moduli in a sample of more than 30 concrete cylinders. The elastic Young’s modulus is a required parameter for structural design. The common practice is to estimate its value from the compressive strength of the concrete (ƒ'c). Currently, there are studies showing good correlation but there are other ones showing poor correlation between the static and the dynamic moduli. Thus, there is a gap in the understanding of their relationship.

On-site evaluation of concrete strength is a main challenge in the condition assessment of existing infrastructure. This is particularly true when the structure under investigation has a high level of importance and traditional methods such as extensive drilling and coring are not an option. Examples of this is the case of damaged bridge structures, storage tanks, foundations under permanent vibration; and heavily reinforced concrete columns. Owners and managers of such facilities prefer non-destructive methods to avoid causing further damage to an already struggling structure.
Non-destructive testing (NDT) methods provide a reliable and effective alternative for testing existing structures. Most of the NDT methods can be performed with no or minimal physical intrusion into the concrete structure. Different methods have been developed over the years to predict the strength of concrete on-site.
In this article, we discuss how recent advances in sensor technology has helped develop NDT methods for predicting strength of concrete. Such NDT methods have the potential to be used in the condition assessment of existing structures; at the same time, they can effectively be used for quality control in the construction of new structures.Compressive strength of concrete is by far the most important property of concrete. It represents the mechanical properties of concrete; for example the 28 days compressive strength of concrete cylinders is the key parameter in most design codes (ACI 318-14, CSA A23.3-14). Strength is also considered (at least in the old school) a key factor for structural and durability performance.

In spite of an easiness of the method obtained results highly depend on the transducers used, coupling quality, and specimen dimensions. In the article the authors focus on the sensor and specimen effects. The results for UPV tests of 6 concrete specimens of different heights and diameters are presented. The specimens are tested with 50 kHz and 1 MHz excitation transducers and the state-of-the-art laser vibrometer (response measurements).
The authors discuss the laser vibrometer readings and the influence of specimens dimensions on the measured pulse velocities. Practical recommendations for the minimal dimensions of the test object in order to minimize the error in UPV tests are proposed.Ultrasonic Pulse Velocity (UPV) method is a very popular technique used in Non-Destructive Testing (NDT) in Civil Engineering. Major benefit of the method is its simplicity. UPV uses the concept of measuring time of a first arrival of ultrasonic wave from one side of the specimen to another. Moreover, UPV is an ASTM standard test method for concrete specimens. The standard specifies the applications of UPV as: assessment of relative quality of concrete, presence of voids imperfections (i.e. voids, cracks, and the effectiveness of its repairs). UPV can be also applied to monitoring changes in the condition of specimen.

Established methods such as penetrant testing (PT) and magnetic particle inspection (MPI) are effective but can lack practicality in some applications. Others, such as conventional eddy current inspection technique (ECT) mainly deploy single element probes resulting in protracted inspection times. Results are also typically greatly affected by operator's skills, material properties and geometry.
Advances in electronics enabled the development of more modern inspection techniques like Eddy Current Array (ECA), increasing the reliability of surface inspection over traditional methods. Indeed, being able to tailor coil designs and multiplexing patterns allows users to optimize the acquisition chain to their specific application. Moreover, by multiplexing and leveraging advanced data processing capabilities, ECA solutions allow inspections to be carried out quickly, often with less surface preparation. They also provide additional benefits such as state-of-the-art imaging (e.g. 2D and 3D C-Scan displays), improved surface coverage, ease of deployment and data archiving. Finally, on top of defect detection, ECA technology can also provide quantitative sizing.
This paper describes the eddy current array method along with variations on the theme, inclusive of their benefits and limitations. The deployment of ECA on real components, subject to representative field conditions is also discussed. Typical applications are presented, providing valuable insights on the use of ECA in lieu of more conventional techniques.A large number of Non-Destructive Techniques (NDT) have been developed and successfully used over the past decades for the detection of surface breaking flaws in various materials, such as: cracks, pitting, corrosion, etc. Those are more or less sophisticated, but all provide valuable information on the integrity of the component being inspected, and come with specific advantages and limitations.

Scan coverage, calibration and sizing techniques are unique for spheres. Scan coverage becomes challenging since most robotic systems function using (X,Y,Z) coordinates and spheres require (r,?,?) Calibration using the spherical distortion compensation can be done using TVG curves with spherical surface induced variance corrections. Sizing a target in a spherical piece is not as straight forward as sizing the same target in a piece with flat surfaces. This is due to the size of the targets being a lot smaller than the beam spread, in addition to the distortion of the sound inside the spherical pieces which makes amplitude sizing challenging.
Inspection qualification is also very difficult since subsurface targets cannot be manufactured. Using real indications is not possible since the true target size is very difficult to measure with standard destructive testing methods. Instead, special performance evaluations can be used to quantify inspection system PoD levels.
Development of other, advanced Non-Destructive Testing (NDT) methods for inspecting spheres is currently ongoing. Phased Array Ultrasonic Testing (PAUT), Full Matrix Capture (FMC) and Time of Flight Diffraction (ToFD) inspection methods are being investigated for potential applications. Custom spherical compensating focal laws have been designed and the adaptive FMC techniques have been applied. Also, ToFD variations generated using PAUT are being developed to compensate for the sound entering the spherical surface.Immersion-based Ultrasonic Testing is the most common method for complete volumetric inspection of solid spheres. Both longitudinal and transverse modes can be used for the inspection; however, the sound field created inside a spherical piece is different from the field created inside a flat piece. The curved surface of the spherical piece distorts the sound modes entering the sphere. This distortion can be controlled and virtually eliminated using different spherical compensation techniques. When very little or no compensation is applied, the sound inside the sphere generates a wide field. When a full spherical compensation is used, a narrow field is generated inside the sphere. Each field pattern has its own advantages and disadvantages.

Recently, a new alternative to MT and PT was developed by Eddyfi consisting in a Tangential Eddy Current Array (TECA) technique using a flexible dedicated probe that contains improved coils designs and multiplexing patterns dedicated to the assessment and characterization of surface breaking cracks in carbon steel welds and structures.
This paper summarizes the concept of tangential eddy current array and describes an in-service PSA vessels welding inspection using the Sharck probe. Examples of resulting data are presented and benefits of TECA are discussed the context of large carbon steel welding.In refining industry, one of most critical components to inspect are Pressure Swing Adsorption (PSA) vessels. Unlike other pressure vessels that are periodically inspected, opened and tested hydrostatically, PSA vessels are externally inspected only due to practical and cost reasons. The external inspection is often an important part of fitness-for-service (FFS) assessment and commonly involves the inspection of large and thick welding using ultrasonic testing and magnetic particles testing (MT). Such inspections were improved by performing Phased Array UT (PAUT) in lieu of conventional UT (CUT) which guarantees an optimized welding volume inspection; however, the welding surface inspection still being performed using magnetic testing or in some cases using penetrant testing (PT). Although these latest techniques are effective, they present some practical issues and does not provide recordable results.

Infrared thermography (IRT) is a non-contact and real time temperature sensing method used for the inspection of materials and structures using the principle that all the bodies with temperature above 0 K emit infrared radiation. Through the measurement of this emitted radiation, IRT allows the detection and characterization of internal defects by analyzing alterations or contrasts in the surface thermal pattern. This paper presents the implementation of an advanced strategy to monitoring and assess pipelines networks by means of automated infrared thermography (AIT), which implies the acquisition, post-processing and analysis of infrared thermal data. The methodology - developed by the R&D team of TORNGATS - is based on the use of an unnamed aerial vehicle (hexacopter model DJI S800 EVO) adapted to transport an infrared camera (Flir T650sc with 640 x 480-pixel array) and the subsequent storage of the data to further offline post-processing and analysis. A matching algorithm based on iterative closest points is implemented to reduce the noise caused by the misalignment and distortions of the drone. Furthermore, the application of multivariate statistical regression techniques on the collected data are used to reduce the noise affecting the fidelity of the signals, improving thus the possibility to detect smaller features without affecting the spatial resolution. The developed methodology allows to considerable reduce the inspectionNon-destructive testing is a key component in the optimization of the plant inspection and maintenance programs. Risk based inspection and reliability maintenance systems require detection, location and sizing of defects or flaws by non-destructive methods. Internal and external damages of pipelines by corrosion and erosion-corrosion is an ongoing problem specially in the oil, gas and power industries, requiring regular inspections and subsequent decisions to ensure safe and reliable performance. In this context, ultrasonic testing, X-Rays imaging and 3D laser scanning are convectional methods currently used to determine the wall thickness of piping and damage produced by corrosion. However particular limitations come out when inspecting large and irregular surfaces. In this scenario, infrared thermography stands as one of the emerging technologies aimed to optimize the inspections processes and maintenance procedures.

A new eddy current technique has been developed that does not require the use of magnets. Near field array for ferritic/ferromagnetic stainless steel (NFA FS) is an ET array solution for thorough inspection of thin walled ferritic/mildly ferromagnetic tubing capable of detecting and characterizing ID and OD defects both in the freespan and below ferromagnetic structures. The NFA FS contains no magnets and uses near field eddy current (a combination of field and eddy current). This paper will review the operating principles of the probe and present laboratory and field experiences from the last two years.Eddy current inspection of ferritic/ferromagnetic stainless steels such as 400 series stainless, Seacure and Monel has always been challenging. The typical inspection method used for these materials has been full saturation eddy current where powerful and carefully arranged magnet assemblies magnetically saturate the tube wall allowing the eddy current to flow as though the material were non ferromagnetic. In addition to mechanical challenges associated with magnet probes, full saturation eddy current is effectively blind below ferromagnetic support structures.

This paper discusses the development and the extension of IRIS technology, including laboratory and field-testing results on typical heat exchanger tubing.
A micro turbine, combined with a dedicated centering device equipped with spring-loaded arms, offers a unique alternative when inspecting small diameter tubes 0.500 in (12.7 mm) at faster pulling speeds. This new centering device concept is highly durable and offers straight C-scan imaging results, which are easier to analyze than conventional IRIS imaging results. At the other end of the spectrum, extra-large centering devices support tube diameters ranging from 3.0 in to 6.6 in (76.22mm to 167.64 mm) at reasonable pulling speeds.
To further extend the applicability of IRIS, a custom single-part flexible turbine and centering device now allows users to easily manage tube bends and elbows by increasing the bend areas inspection zone that can be scanned in a single pass.
The development of these new advances in IRIS technology proved to be challenging, but results in a wider range of applications for the IRIS technique for the industry.The internal rotary inspection system (IRIS) is a UT technique commonly used to inspect a wide range of ferrous and non-ferrous tubing materials in heat exchangers. The technique has proven efficient and reliable in detecting and sizing general wall loss and localized corrosion from the inside (ID) and outside (OD) diameters. IRIS is the most popular inspection technique worldwide for its sizing capability. The most common IRIS systems are, however, only suitable for the typical 1.0 in (25.4 mm) and 0.750 in (19.05 mm) tubing and offer a relatively low pulling speed.

According to Transport Canada, between 1997 and 2006, 28 train derailments occur because of an axle failure. Traditionally, axles are inspected using typical surface techniques such as MT, PT and UT at the extremity. A typical train axle would normally be solicited in all the possible stress orientation such as bending, compression, traction, torsion, and shear. This phenomena make it unlikely to predict the orientation of an induced fatigue crack. This paper is going to demonstrated that a multi-oriented phased-array inspection approach would increase the probability of detection, the interpretation capability and the productivity compared to conventional technologies.With the petroleum boom in the western part of the country, the rail industry’s oil transportation sector has grown significantly in the last decades. The safety of that kind of transportation method has also took an important part of the public debate space lately. The Lac Mégantic tragedies and other derailment causing environmental causality in northern Ontario have contributed to that debate. Generally an accident is caused by one of the following reasons: an human mistake, rail failure or train mechanism/component failure.

Most of the in-service inspections are performed using manual UT techniques, which are easily deployed and often give satisfying results but also have strong limitations, the main one being the impossibility to get images as inspection results. Obtaining C-scan is highly desirable for in-service applications in order to increase the probability of detection, improve the results traceability or provide guidance for repairs. Different phased-array solutions exist to obtain C-scans for in-service inspections but they require the use of mechanical encoders or scanners which also bring their own limitations: limited inspection surface, restrictions on the operator movement, problems adapting the scanner to curves and complex geometries inherent to an aircraft.
We present a novel inspection technique using a portable phased-array UT instrument coupled to a dynamic tracking system based on stereoscopic cameras. The 3D vision device follows the trajectory of a custom target mounted on the phased-array probe. A software application was developed to perform real-time transformation of the 3D linear and angular coordinates into the 2D scan-index coordinates and skew angle required by the UT instrument. A complex double curvature aerospace component was inspected with the developed method. The UT probe was moved freely in any direction on the inspected surface (Paintbrush movement) without any physical encoder nor scanner attached to it. Ultrasonic C-scans were generated. The accuracy of the defects positioning and sizing as well as the overall performance of the method are discussed.The proportion of composite materials used in modern aircraft primary structures is continuously increasing because of their high mechanical performance and low density allowing for significant weight savings. Various factors can harm composite parts during the in-service life of the aircraft (impacts, collisions, lightning strikes, dropped tools, etc.) causing subsurface damages such as delaminations or disbonds. The structural integrity should therefore be verified throughout the lifetime of the aircraft. Ultrasonic testing (UT) is the preferred method to perform non-destructive inspection of composite aerospace components.

A single element system was developed which made use of reflection mode imaging by placing a piezoelectric transducer within the water cooling stream of the copper electrode. This system performs well in many situations, but has been difficult to adapt to cases where the geometry is not axisymmetric. To overcome this limitation, a phased array system has been developed that can monitor the weld along a cross sectional area. This system is used as both an independent tool or an investigative tool for welds in which the single element is unable to investigate.
The phased array system was applied to monitor less ideal welds and investigate the quality degradation due to common defects such as expulsion, lack of fusion and under welded sheets. The results of these cases and limitations of the system shall be discussed.

In general, these calibration blocks have been manufactured using conventional methods, with known size reflectors implanted using Side Drilled Holes (SDH), Flat Bottom Holes (FBH) and notches by precise machining or the use of Electrical Discharge Machining (EDM).
However, conventional methods have limitations when attempting to produce internal discontinuity representation or when external surfaces have complex features. The use of additive manufacturing process provides a solution to these restrictions and may produce more functional and lightweight calibration blocks.
In this paper/presentation we will review the results of initial attempts to qualify level of sensitivity achievable vs. known reference standards, and finally, the results of an AM produced geometry calibration block with known internal and open to surface discontinuities.

Recent advances in Eddy-Current Array (ECA) coil design and multiplexing patterns enabled crack detection and sizing in ferrous materials. The main objective behind the development of these new Tangential ECA (TECA) probes was to determine the optimal set of parameters to obtain a clear discrimination between surface breaking defects, lift-off and permeability changes while still being able to monitor and quantify each signal individually. By multiplexing and leveraging advanced data processing capabilities, this ECA solution allows inspections to be carried out quickly, provide accurate depth sizing of cracks and eliminate the need to remove protective coatings. This new approach offers additional benefits such as state-of-the-art imaging (e.g. 2D and 3D C-Scan displays), improved surface coverage, ease of deployment and data archiving. Furthermore, the new sensor and technique developed allows inspections to be carried out under the mainstream ECT certification.
This paper describes the application of Tangential Eddy Current Array on pipelines for the detection and sizing of SCC. Specifically, the development consists of a high resolution multichannel probe connected to a portable acquisition system. Numerous tests were conducted on both manufactured and real defects in X52 samples. The result is a probe deployable on various pipe diameters ranging from 25 to 125 cm (10 to 48 in) and capable of detecting colonies of longitudinal surface breaking indications such as SCC. Defects longer than 5mm (0.2?) are sized with ?10% accuracy in the 0.25-3mm (0.01-0.12?) depth range while lift-off is monitored and compensated up to 1.5mm (0.06?). Potential to replace MPI and UT as the industry gold standard for fast and reliable SCC detection and sizing on carbon steel pipelines is shown.

Typical ADR applications are the detection of porosities, inclusions or cracks in casting parts. It is possible to define certain ROIs and check defect metrics like defect density, defect distance, defect size, defects per area and many more. Thresholds can be defined dynamically. Training of the system does not require any programming skills and can be done through level II or III personnel. This drives down production costs and reduces the inspection bottleneck, while increasing the reliability and process safety. An integration to Industry 4.0 factory solutions allows full traceability of the inspection process down to single part level.
More demanding tasks like automated measurement, completeness or density checks can be performed through the unique VAIP (VisiConsult Automated Image Processing) module. Complex test sequences can be performed on static images or in real time. Example applications: The behavior of heat pumps under different temperatures and completeness checks of valves.

? The Murray (depicted by an Aboriginal man and an ibis)
? The Torrens (depicted by a woman and a black swan)
? The Onkaparinga (depicted by a woman and a heron)
The Murray statue was cast in the early 1960?s in hollow sections from a cast aluminium. The sections were welded together and the fully assembled statue mounted on a granite base. Following a recent event where the mounting failed with the statue falling to the ground breaking into several pieces.
Findings of the initial visual inspection, in consultation with the asset owner an inspection and test plan was developed using computer radiography to evaluate the structural integrity of the Murray statue. Key test areas were identified to evaluate the process of repair. The following critical areas were identified:
? Mounting ? Torso of the statue, bolting points.
? Weld zones- Torso to the limbs, neck, hands etc.
? Head section and Ibis.
? Extent of cracking to be evaluated based on visual inspection results.
? Remaining wall thickness.
Computer radiography was conducted using a Rigaku X-Ray Unit and Kodak Computer Radiography system. Computerised radiography effectively identified the following:
?-Numerous areas of parent metal loss \< 6mm.
?-Welded joint locations, preparations and configuration
?-Weld penetration
?-Prior (unknown) repairs to the statue
?-Cracking evident at critical change of sections
?-Damage sustained from impact, not visible by visual inspection

Ultrasonic calibration requires the measurement of several variables. Both test part and the test equipment variables are required. The test part variables include velocity and attenuation. For contact testing, the test instrument and probe include normalization or sensitivity, and directivity.
Standard ultrasound calibration techniques are traditionally not applied to the Full Matrix Capture (FMC) technique. FMC data is a large matrix of captured A-scans. All the A-scans are processed into stacked views where A-Scan signals are mapped to positions. These A-Scan stacks generate detailed images that relate the acoustic response to spatial positions inside a test component. Most of the FMC processes are fairly mathematical in nature and all images are generated using many A-Scans.
FMC can be calibrated using mathematical models. These mathematical models vary between different FMC systems. Currently there are different methods and views or opinions regarding how FMC should be calibrated.
This article addresses the question ? What is actually needed to calibrate FMC data and how does this compare to standard code accepted Ultrasonic Testing (UT) calibration methods?
In 2001, the Thermographic Signal Reconstruction? (TSR?) method was introduced and shifted the emphasis from visual image evaluation to independent analysis of the time history of each camera pixel. The basic TSR process, in which a noise reduced replica of each pixel time history is created, yields improvement over unprocessed image data that is sufficient for many applications. Examination of the resulting logarithmic time derivatives of each TSR pixel replica offers significantly greater feature to background contrast, enabling the detection of small, deep and subtle features that cannot be detected by visual evaluation of the unprocessed IR images.
Additionally, examination of the resulting logarithmic time derivatives of each TSR pixel replica also provides significant insight into the physical mechanisms underlying the active thermography process. The deterministic and invariant properties of the TSR derivatives provide the basis for inspection criteria which have enabled the successful implementation of automated defect recognition and measurement systems. Unlike most approaches to analysis of thermography data, TSR does not depend on flaw to background contrast and can also be applied to the characterization and measurement of flaw-free samples.
We will present a review of the underlying theory of TSR and demonstrate a number of quantitative applications, including part thickness measurement, defect depth measurement, coating thickness measurement, and porosity measurement.
The rotating magnetic field ideally consists of two perpendicular harmonic components of equal frequency and a 90 degree mutual phase shift. In a presence of a nonlinear material (which is mostly the case) higher harmonics are generated. Moreover, heavy use of switching sources has changed power AC current waveform that it is no longer sinusoidal.
Higher harmonic components are likely to change the magnetic field polarization nature. This paper investigates nonlinear effect and its impact on a polarization of magnetic field and MPI detection ability. It has been found that higher harmonic components may cause blind angles, eg. directions in which cracks are not likely to be detected. Examining the impulse of magnetic force affecting a particle, the total effect of higher harmonic components in MPI is evaluated.

metal bonds have to be used for the inspection of composite laminates. Depending on the type of discontinuity the requirements of the inspection task are very diverse and time
consuming. Due to the differences in the lateral and axial dimensions of defects and the attenuation varieties it is necessary to measure as broad-banded as possible. Typical bandwidths as implemented in contact testing methods cannot be used in air-coupled ultrasonic testing at the moment.
We describe an efficient implementation of such an inspection with significantly improved results compared to conventional systems. It is based on a new multi-element air ultrasonic
transducer. Each of the elements has different frequencies. The overlapping sound beams of the individual elements allow generating a broad-band signal which can be additionally
steered inside the material as it is well-known from phased-array UT.
The new transducer increases the bandwidth considerably by an in-phase simultaneous activation of all elements. In order to operate such an ultrasonic transducer a special senderreceiver
electronic is necessary. As the individual transducer elements have to be activated simultaneously the system must have at least as many channels as the ultrasonic transducer. Additionally all channels with different frequencies have to be activated with a very high time accuracy relative to each other.
The evaluation takes place under consideration of the dispersive properties of the inspected test objects with respect to the interdependency with ultrasound. Frequency-dependent
properties like attenuation as well as geometry characteristics such as scattering behavior at interfaces cause a change in the measured ultrasonic signal. Accordingly, it is possible to
achieve new contrast mechanisms. An increase of the effective bandwidth by combining a multi-element air-coupled ultrasonic transducer and a multi-channel measurement system
allow gaining more information of the sample in only one measurement cycle. This accelerates the measurement of different frequencies drastically and eliminates uncertainties during the alignment of transducers with different frequencies.

Furthermore, it allows to work in full parallel or by using several active apertures on the same probe. Hereafter is a list of applications where the FAAST technology brings added value:
Prior to all with the first reference, the FAAST can perform an on-track rail inspection at a speed of 100km/h using a 1D linear multi-element probe generating up to 16 oriented beams from 35? to 70? within a single shot, including a 0? shot to verify the coupling at each shot.
Reference in Aircraft Industry for special alloy and titanium turbine disc inspection complying with Multi-zone testing procedures aiming at the detection of down to ?0.4mm FBH at 2.5mm up to 140mm depth from the surface. Multi-zone testing procedure requests Multi-focused and/or Multi-oriented beams generation within a single spray throughout a 2D matrix probe, reducing thus considerably the inspection time per turbine disc.
A feasibility study in Aircraft Industry for aluminium plate has been performed using the multiple focused aiming at the detection of ?0.8mm FBH from 2mm up to 160mm depth from the surface using a single 1D linear 128 elements phased array probe with a width of 120mm. As the FAAST allows to generate all focusing delay laws in one single shot, the scanning speed reached 700mm/s while the performances answer the Aircraft standards in terms of SNR.
A feasibility study in Bars application has been performed using the multiple angles to detect ?0.8mm FBH and longitudinal notch. By using a curved phased array probe, the FAAST generates the 0? and ?45? angles in one single shot allowing thus an increase of speed of 60.

Recently, the suitability of lasers as a contactless excitation source has been investigated and it was shown, that cracks can be detected. As the specimens are locally heated, a heat flow is initiated. Those heat flows can be used to detect crack-like defects that are perpendicular to the surface. However, the suitability of the laser-excited thermography to detect inner defects like voids and the influence of geometric as well as excitation parameters on the test result has not been fully investigated. Therefore, this study focus on the detection of inner defects in metallic components.
In a first step, thermographic measurements with varying excitation parameters were performed. The obtained results were than used as a basis for the numerical simulation of the testing process. A parametric FE-model has been implemented and the influence of excitation as well geometric parameters on the testing results were determined. Different approaches to evaluate the resulting surface temperatures were considered as well. The simulation results were than compared to the experimental data that was obtained by testing idealized specimens with porosities. Based on these results, the most relevant parameters are determined and limiting factors resulting from the experimental setup are discussed.

Aerospace rotary parts require extremely high manufacturing standards. These components are thoroughly inspected using various NDE methods to ensure that no internal flaw would be capable of causing catastrophic failures. Among these methods, the most consolidated is ultrasonic testing. Low-cost single-element probes are usual, but they require the inspected parts to have flat surfaces. Therefore, pre-machining of forgings to a sonic shape is common to allow a predictable sound path and coverage. This machining ensures high repeatability and sensitivity, but with the drawback of being cost-intensive. Avoiding this machining step would drastically reduce the cost of production and the environmental footprint of the process. Phased array ultrasonic inspection represents an interesting option. With advances in the last 20 years, researchers have shown that multi-element probes can render internal flaws with high-resolution and outstanding sensitivity. Even in the case of parts composed of curved shapes.
In this context, this work advances towards eliminating the sonic machining step, enabling the inspection of as-forged components. For this purpose, a novel approach was proposed and evaluated. It consists of combining robotic automation with advanced phased array ultrasonic imaging. Using the robotic arm, the probe position and orientation could be adapted to the complex surface of the part under inspection. A proof-of-concept was conducted using a testing specimen made of stainless steel 430 and designed to represent a section of an arbitrary forging of a rotating part. The specimen's profile was composed of concave and convex curvatures. A total of 30 artificial internal defects were introduced at semi-random positions, consisting of side-drilled holes of 1.5 mm. A Staubli TX-90 robotic arm was used to position the probe at the desired standoffs. While a Verasonics Vantage 64-LE was used to do a full matrix capture at each position. The best image performance was ensured by correctly placing the probe at the ideal distance from the specimen surfaces using the 6-DOF robotic arm. A fixed region of interest was used to apply the immersion total focusing method (TFM) at each optimized probe position. This way, the part could be insonified from different directions. Finally, a global TFM image was rendered by composing TFM images obtained with the probe at several probe standoffs and positions. In the results, images obtained at non-optimized probe positions revealed artifacts and poor performance. While the optimized images correctly showed the indications of all defects inside the tested specimen. Therefore, demonstrating the potential and capabilities of the proposed method.

The advent of digital x-ray radiography and the global increase in computational possibilities have birthed the development of automated computer-based NDT inspection, and image evaluation solutions often based on computer-vision solutions which were originally developed for visual photographic images. Additionally, there is a prolific development of Artificial Intelligence (e.g., machine learning, deep learning) solutions for the same purpose [5, 6]. Although these solutions offer a promising pathway to achieving 100% inspection of manufactured parts with a much higher throughput relative to human inspection, the compliance of such published solutions to operational NDT Standards in the industry are often unclear.
This work aims to explore the development of a well-structured framework for the conformance of ADR solutions to operational NDT Standards in the industry. Subsequently, as defect is a representation of a flaw/group of flaws that meet the reject criteria of a relevant Standard (or client-specific specifications) [7], we shall consider, as the baseline for the development of a defect grading algorithm, the digital x-ray reference Standards ASTM E2973-15 Standard Digital Reference Images for Inspection of Aluminum and Magnesium Die Casting, designed for visual inspection. Flaws listed in this Standard with corresponding reference digital images include Porosity, Cold Fill, Shrinkage, and Foreign Materials. The flaw characteristics ranging from the shape, grey value, distribution, size, representation (e.g., superimposition of multiple flaws) etc., further adds to the complexity of the problem. An assessment of the relevant digital image parameters that affects flaw detection, and simulation-based training of detection algorithms shall be explored.

Brazing joins two sheets along a seam using a filler metal. In the brazing process, the filler metal is heated, along
with the parts to be joined, to a temperature above the melting temperature of the filler material. This allows the
filler metal to wet the surfaces of the parts to be joined through capillary action, resulting in the formation of
metallic bonds, ultimately forming the joint.
Brazing, like all joining methods, is also susceptible to process variations. These process variations can include
wear of the laser, plate misalignment, and external temperature changes. If left unchecked, such variations can
eventually lead to the formation of defects, which bring a joint outside of the performance criteria specified in its
engineering design. As such, reliable evaluation of these joints ensuring adequate quality is of great importance.
To do this, the development of a non-destructive evaluation technique based on ultrasound phased array measurement has been investigated and determined viable in its application.
In this work, we explore refinements to the imaging process, including the use of multi-angle acquisition,
optimizations related to the array geometry, and the selection of an optimal coupling medium. These
optimizations allow for improved robustness of the imaging process with the resulting comparison to prior
acquisition techniques discussed.
In order to create electrical contact elements, thin sheets of highly conductive materials, for example copper, can be joined by resistance spot micro-welding (RSMW) using copper-tungsten composite electrodes. A new technology to manufacture those electrodes was introduced by the Technische Universit?t Dresden. The joint formation during RSMW is realized due to Joule heating generated by the tungsten insert and controlled heat release into the workpiece. To evaluate the spot welds in real-time, the Tessonics? Real-Time-Integrated-Weld-Analyzer (RIWA) with a single-element 15 MHz transducer is used to collect ultrasonic images in pulse-echo mode. Because the composite electrode has got one additional interface (copper-tungsten), an additional reflection of the ultrasonic signal needs to be handled.
The goal is to derive both qualitative and quantitative information about the structure and properties of the weld in real-time from the ultrasonic B-scans for RSMW of thin copper sheets.
Based in Alberta, the company employs 45 techs and engineers and is well known in the field of electromagnetic inspection equipment.

These simulation tools were compared for normal incidence in steel and reflection on a side-drilled hole. Full matrix captures were simulated and the results were compared in terms time of arrival, amplitude and computation time. Finally, a method for reducing the simulation times while keeping the capabilities of finite elements has been developed [3]. It aims to use an analytical propagation model in all areas that one does not wish to inspect (e.g. wedge or water).

many studies to focus on using multi-modal platforms for remote inspection of industrial components. In remote
inspection, acquiring data from different modalities can result in more comprehensive component analysis. Also,
the extended amount of data regarding the components and environment can prevent possible data
misinterpretation and human mistakes in the post-analysis phase. Despite the benefits of such systems, fusion,
alignment, and calibration of multiple modalities can present many challenges. One of the most common
approaches for aligning and calibrating multi-modal imagery data is to use reference/calibration boards with
geometrically known features to estimate sensor parameters and required transformations for aligning different
modalities. Taking advantage of reference boards can address the challenge of dissimilarity of features in
different spectrums. This study introduces a complete solution for multi-modal inspection using aerial platforms.
The presented solution includes three main parts: (a) a hardware setup that can work as a standalone system or a
payload for drones; (b) an embedded software system; and (c) a self-heating calibration/reference board. The
presented system provides the required features for synchronously recording, transmitting, fusing, registering,
and visualising thermal, visible, and depth data. The multi-modal data fusion technique presented in this paper
forms an RGBD&T data that each point presents the thermal, texture, and relative 3D position information. Also,
a registration technique is proposed to combine multiple RGBD&T data to form a 3D thermal-visible view of an
industrial component. Moreover, a novel self-heating calibration board using TEC modules provides a sharp and
distinguishable pattern in thermal and visible modalities. The introduced reference board is also designed to be
used as Ground Control Point (GCP) for drone surveys.
The use of an inline resistance spot weld monitoring system making use of single-element ultrasonic transducer has been proven an effective monitoring solution in a vast majority of situations. This system, although robust, has limitations in that it relies on a symmetry that cannot be guaranteed with electrode misalignment and some defects, such as porosity, that are becoming increasingly common with the use of aluminum construction. With these challenges in mind, the development of a phased array monitoring system was undertaken.
The use of a multi-element, or phased array system, allows for the creation of a 2D video of the spot weld process. Monitoring a cross sectional view of the spot weld process has shown that the presence of symmetry-breaking defects, as well as a more robust monitoring process in the presence of misalignment, is possible. This system has been tested for use in both phased an non-phased array operation modes, allowing for the potential for a replacement of current single-element systems. Such a system is crucial to the quality assurance process as the automotive industry moves forward in an environmentally conscious world.
spot joints which hold the metal parts together. Resistance spot welding is a
commonly adopted process to join metal sheets. Two electrodes squeeze the parts
and send electric current through them to melt local region and fuse the
sheets. Quality of such joint depends predominantly on the size of the weld
nugget in both lateral (diameter) and vertical (melt penetration) dimensions.
A team from the Institute for Diagnostic
Imaging Research has invented an ultrasonic system for automated inspection of
such weld joints in real time, as weld is being developed. The ultrasonic
waves, reflecting from the solid-liquid boundary of the molten region of the
weld bring back to the transducer the information about the size of the nugget
and its relative position with respect to the sheet stack surfaces. Such an
approach eliminates the use of expensive and labor-intensive destruct tests. On
top of that, it provides the way to zero-defect spot-welding by enabling all
100% of weld joints to be inspected, if needed.
IDIR teamed up with Narmco Group to scale
up the implementation of this technology to the multiple welding cell level. Five
ultrasonic inspection systems are being installed on the robots running in two
welding cells at Central Stampings Limited in Windsor, ON. Use of multitude of
such inspection devices will provide an insight on the spot welding assembly process
at the plant scale. Information about parts inspected automatically and
non-destructively is streamed up to the data aggregation server to create
global NDE 4.0 picture of the assembly process quality. Automatic aggregation
of this data at a company-wide scale paves the way for the advancement of the
process control to the Industry 4.0 level.
(Prof. X. Maldague, U. Laval + TORNGATS)This study presents preliminary results of ongoing research on using passive Infrared Thermography (IRT) to inspect civil infrastructures. Specifically, we used numerical simulation to help decision-making when planning windows for thermographic inspection. A small concrete sample was modeled using the Finite Element Method (FEM), simulating a slab with different configurations of internal voids. The detectability of damages and the effects of the presence of reinforcement on the detectability of internal damages were investigated. The preliminary results showed that, during the heating time, the defect above reinforcement appeared with lower contrast than the defect present in the concrete sample without rebars. In addition, it was confirmed the influence of area and depth of delamination in the thermal gradient results.

The aim of this project is to develop a decision support algorithm for inspectors through artificial intelligence (AI). The AI tool would help in identifying, locating, and sizing defects while also giving a probability of certainty. The AI tool would display a real-time interpretation as an overlay on the PAUT images.
In the last decade, AI in computer vision has proven to be efficient in many classification and detection tasks. This is the case for example in the medical field or in autonomous driving where AI is commonly used. As for PAUT, research has also shown that machine learning could allow to detect defects with an accuracy comparable or even superior to that of qualified inspectors [1]. However, the use of computer vision in PAUT remains very limited. This is mainly due to the difficulty to access large databases of labelled inspections. Indeed, machine learning requires a considerable amount of training data. While it is easy to access sizeable labelled databases of photographs or MRI scans for example, it is not the case in PAUT because the inspection results are typically confidential.
In this project, a large database will be generated using sample defects that are normally used to train and evaluate inspectors. The different defects contained in these samples will be used to train AI algorithms. The inspections will be performed with several different probes and at several frequencies. Each inspection will be performed using the Full Matrix Capture method which allows for a multitude of possible image reconstructions for each inspection including standard sectorial scans. Following this method, the database will contain several tens of thousands of scans representing a dozen different defects.
Based on the most recent work in machine learning, the most efficient methods will be adapted to PAUT. The combination of a powerful and fast detection algorithm with a large database will create a practical and robust real-time decision support tool.
This ASQ 2021 Crosby medal winner handbook is designed with a purposeful scope, covering all levels of inspector competencies, and is configured by taking into consideration all aspects of field industrial radiography (i.e. education & training, qualification & competency, techniques development & application, code compliance & interpretation), and most importantly, will prove to be handy field guide for routine reference.
The handbook not only provides readers with the learning opportunity for attaining industrial radiography certification, but also serves as a field reference where all relevant data (i.e. sensitivity charts, density tolerances, several inspection techniques & other relevant information), are available in one treatise, for a code compliant radiographic inspection and evaluation with correct interpretation.
The presentation takes the audience through different aspects of industrial field radiography covered in ASQ 2021 Crosby Medal winning handbook. The book is presented as a tool for bridging the gap between knowledge & understanding of industrial radiography, and its correct application.
Approaches for thermogram processing based on deep learning and the possible addition of a visible channel combined with proper data fusion
are overviewed as well.
Recent aircrafts incorporate an high content of composite materials such as Carbon Fiber Reinforced Plastic (CFRP) used in wings, fuselage, etc.
Such materials require proper inspection to detect and assess severity of embedded defects present at manufacturing stages such as porosities and in-service defects (delaminations and disbonds).
Since surfaces to inspect are large and time for inspection should be limited as much as possible, quick inspection schemes are preferred.
Many other fields could benefit from thermographic drone NDT, for instance civil engineering with large structures sometimes difficult and dangerous to reach.
Finally, some case studies are presented including a flying demonstrator as well.

Thus, the infrastructure industry requires efficient, simple, inexpensive, and effective means for non-destructively inspecting BF and EF joints. To this end, we developed and evaluated a system that classifies ultrasonic A-scans from BF and EF joints as either "flawless" or "defective", and subsequenty according to defect type if necessary. For BF we used a pitch-catch method with a custom-designed ultrasonic chord transducer, while for EF we used a pulse-echo approach. Signal classification was performed using deep learning with convolutional neural networks (CNNs). To train these networks, we first contrived a set of perfect and defective BF and EF joints, using pipes having outer diameters of 2-, 4-, and 6-inches as they are the most common in industry. A variety of common defects, e.g. cold fusion, contaminants, voids, etc. were then simulated at various positions along the joints and with varying defect severity. After creating the joints, we inspected them using phased array ultrasound to confirm the presence of defects and mark their positions on the joints.
Subsequently, using our ultrasonic systems, we developed datasets of A-scans that we classified as flawless or defective and according to defect type based on current industry standards. We then trained CNNs for defect detection and defect classification, which varied in terms of performance across the different joint types and pipe sizes. Defect detection F1 scores ranged from 0.92-0.97, while defect classification proved to be much more difficult yielding F1 scores ranging from 0.48-0.95.
Our work shows that efficient, simple, inexpensive, and effective defect detection and classification for BF and EF PE pipe joints is possible through the use of ultrasound-based NDE supported by artificial intelligence developed using deep learning techniques.

York started as a development engineer for ultrasound transducers and was promoted to be the engineering manager for probes after a short time as well as the manager for the application labs in Germany and France. York earned a Diploma in Physics in 1999 followed by a PhD in 2002, both from the University of Muenster (Germany).
The first step in achieving this goal seems obvious – to integrate a conventional ultrasound device and transducer with a robot. However, there are many steps in the manual inspection process that are performed by an operator and subsequently need to be automated in a process-safe manner: positioning the ultrasound transducer correctly on the surface, recording and automatically evaluating the ultrasound data, and communicating in a fail-safe manner over an industrial network are only some aspects for which a solution must be found.
This presentation will discuss the requirements for an ultrasonic system for automized spot weld testing, as well as present an already implemented smart robotic system for this purpose, which allows for both out-of-line as well as inline testing in series production.

This paper presents a study of progressive damage of GFRP bars. The bars are subjected to accelerated ageing in alkaline solution and elevated temperature. The study offers three
sections: (i) ultrasonic evaluation based on wave velocity and amplitude attenuation approaches,
including characterization of ultrasonic transducers using the state-of-the-art laser
vibrometer. The responses are measured with ultrasonic transducers in an axial and transverse
direction. (ii) The numerical simulations adding a more comprehensive understanding of wave
propagation and investigating other testing methods, and (iii) a destructive shear test
carried on the bars. The experiment investigates the level of damage in bars and verifies the
ultrasonic evaluation.
The comparison of ultrasonic evaluation, destructive shear test, and numerical
simulations shows that ultrasonic techniques can successfully predict the degradation of shear
strength (and ultimately tensile strength) of GFRP bars (maximum error of 7%).

integration of a number of technologies including automation and process control, augmented reality, digital twins, AI, and machine learning, and the integration of NDE within corporate and even global levels of data management and resource planning.
An increasing amount of automation and
integration is already visible in many sectors of the NDE community, and the benefits are manifest. Nevertheless, it can be confusing or even daunting to think about all of the implications of the emerging future that we have been
calling NDE 4.0. Many inspections are still operating in an analog (NDE 2.0) way. Some have automated and digitized portions of their NDE processes, but not integrated them with the factory: NDE 3.0. Many of us are not sure how – or whether – we should approach a greater level of automation and integration, what the benefits might be, and what efforts would be involved.
In this paper, we will offer some ways to think about “NDE 3.5” or the incremental steps between the current state of our NDE systems and processes, and the potential NDE 4.0 future. We will discuss some of the opportunities for higher levels of automation and integration, and the benefits that can come from their implementation, even if a full NDE 4.0 level of integration is not the end goal.
