    Reconstruction of Defect Paths Using Eddy Current Testing Array 3D Imaging

    In a world where the reliability and lifespan of industrial equipment are critical, our research aims to go beyond the traditional limits of non-destructive testing. We seek to achieve accurate detection and comprehensive imaging of defects in their various forms by harnessing the capabilities of eddy current testing with multiplexing technology on multi-element sensors. This approach allows us to save time and ensure the quality of results. This paper presents a method for detecting and imaging different defect paths on an aluminium plate. Our methodology involves the strategic deployment of multi-sensor techniques specifically designed for eddy current testing. To address the inherent challenge of mutual magnetic induction between these sensors, we employ the alternating feed method, which is an advanced technology that ensures data integrity and significantly accelerates scanning times. By combining this technology with multi-sensor techniques, we capture signals that provide valuable insights into the presence of defects. Additionally, we produce 3D imaging that enables us to trace their paths, regardless of size. These preliminary results lay the foundation for future research aimed at accurately characterizing and visualizing the shapes and dimensions of these defects, thereby contributing to a more comprehensive understanding of defect behaviour.

    Defect characterization from magnetic field leakage signals in petroleum and natural gas pipelines

    Pipelines transport invaluable energy resources such as crude oil and natural gas over long distances. The integrity of the piping system in terms of safety of the process is then of high importance. However, pipes are prone by time to defects that may degrade their properties and lead to failures. In this paper, we study the effect of defect parameters on the magnetic field leakage captured by Hall sensors operating along the pipe. In fact, the obtained results show that the defect parameters influence directly the MFL amplitude and shape. For this reason, the inversion problem allowing us to reconstruct the defect from the MFL signals became fast and easier in comparison to the deterministic and probabilistic algorithm inversion procedure. However, the simplified system cannot describe the real defects and the three-dimensional numerical study became necessary. In tank floor inspection domain, as our recent published work, we have studied the performance of defect shape reconstruction from MFL array sensor imaging and depth estimation while using an iterative inversion method. Indeed, the first stage consists of determining the defect width and length from magnetic flux leakage mapping reconstructed from the recorded signals of the micro-integrated magnetic sensors. Then, after coupling Comsol and Matlab software, the defect depth is obtained by coupling the 3D finite elements method and a fast iterative algorithm recently developed. Consequently, the defect shape and size are obtained after a few iterations with high precision. Furthermore, this method of defect reconstruction and seizing can be extended for irregular defect shapes encountered in pipeline such as cracks and corrosion.

    Static eddy current imaging for nondestructive testing of aeronautical structures

    Non-destructive testing (NDT) plays a crucial role in ensuring the safety and reliability of the structures used in aeronautics as it enables the detection of defects without damaging the parts examined. In the field of aeronautics, it is necessary to ensure the structural integrity of aircraft components. Vaulted head bolts are the most commonly used in this area to assemble multi-layered structures due to their strength and ability to maintain the structural integrity of aircraft. Examining these assembly areas can be challenging and present unique hurdles for non-destructive testing due to the shape and structure of the rivet, particularly its curved surface. This curvature can result in varying lift-off distances during surface scanning and alterations in the path of swirling currents near the rivet. Consequently, the response of vortex currents may vary, complicating the precise interpretation of test outcomes. In recent years, researchers have concentrated on devising advanced techniques for vortex testing to identify defects in complex structures, particularly those found in the aerospace industry. In this study, we have devised a model employing the finite element method (FEM) using COMSOL Multiphysics for non-destructive testing via 3D imaging utilizing a grid of multi-element vortex sensors distributed across multiple layers around the rivet, without necessitating the displacement of this grid. Our investigation, which involved analyzing various changes in lift-off distances for the sensor, demonstrated the accuracy of defect detection near the rivet, irrespective of the length and width of the defect. We propose a promising solution to tackle both the rivet's shape and the issue of probe displacement during testing. The sensors' non-displacement eliminates parasitic signals, preventing errors in signal interpretation, while multiplexed powering eliminates mutual inductance between adjacent coils.

    Non-destructive rapid defect testing around curved head rivets without displacement of eddy current sensors

    In the field of aeronautics, it is essential to ensure the structural integrity of aircraft components. Non-destructive testing (NDT) plays a crucial role in ensuring the safety and reliability of structures used in aeronautics as it enables the detection of defects and imperfections without damaging the inspected parts. Domed head rivets are commonly used in aeronautics to assemble multilayer structures due to their strength and ability to maintain the structural integrity of aircraft. However, inspecting these assembly areas can be challenging and presents unique challenges in terms of non-destructive testing due to the curved surface of the rivet, resulting in lift-off variation during surface scanning and a modification of the trajectory of eddy currents near the rivet. This can lead to changes in the response of eddy currents, complicating the accurate interpretation of test results. In recent years, researchers have focused on developing advanced eddy current testing methods to detect defects in complex structures, such as those found in aeronautics. In this work, we propose a promising solution to address both the shape of the rivet and the probe displacement issue during testing. We have developed a model based on the finite element method (FEM) using COMSOL Multiphysics for non-destructive testing through 3D imaging using a matrix of multiplexed multi-element eddy current sensors distributed over multiple layers around the rivet without the need for the displacement of this matrix and capable of adapting to the variation in the diameter of the domed head rivet. The non-displacement of the sensors eliminates parasitic signals that can lead to errors in the interpretation of obtained signals, and the multiplexed powering of the sensors eliminates the mutual inductance effect between adjacent coils.

    Non Destructive Testing by Magnetic Leakage Flux Applied to Ferromagnetic Parts

    The non-destructive magnetic flux leakage control is very important because it is used for conductive parts and is based on the circulation of a magnetic field through the thickness of the tube. Magnetic Flux Leakage (MFL) is a corrosion and crack detection technique for ferromagnetic materials, which is mostly utilized in metal pipelines and tanks. It is based on the use of a strong magnet to magnetize the equipment's wall. The magnetic field "escapes" from the wall where there is corrosion or a lack of substance. The magnetic field leakage is measured using a magnetic flux detector situated between the magnet's poles. A magnetic flux detector placed between the poles of the magnet measures the magnetic field leakage. A magnetic field sensor is also used in the magnetic leakage flux approach to obtain a defect signature. The magnetic leakage flux test works by magnetizing the part to be examined with a magnetic field and then detecting the leakage of the generated field lines with a magnetic sensor. The principle of magnetic leakage flux testing is to magnetize the component to be tested with a magnetic field and detect leakage of the field lines caused by the presence of a defect in the part using a magnetic sensor. In this work, we have given a description of the magnetic leakage flux sensors. We listed the Maxwell equations that regulate the MFL detection phenomenon, as well as a brief summary of the software utilized, COMSOL multiphysics, and a simulation result of this control. Last but not least, there's the transition from process to modeling. using a COMSOL multiphysics 3D simulation for low carbon and faulty steel sheet on the one hand, and for cylindrical parts with internal and exterior flaws on the other.

    Non Destructive Testing for a Multilayer Structure used in Aeronautics by Eddy Current Multi-Sensor System

    The goal of non-destructive testing (NDT) is to determine a part's integrity without causing damage to it.

    3D Imaging by Eddy Currents From Multi-Element Sensors in Multiplexed Mode Applied to Multilayer Structures Used in Aeronautics

    The Eddy Current (EC) technique is widely used in the field of non-destructive testing of electrically conductive materials. It is easy to implement and robust in industrial applications, but it is relatively costly when large surfaces of parts to inspect are involved. New reliable and quick testing systems are emerging such as eddy current imaging systems which have recently been developed to produce EC images with good defect characterisation performance. It is obtained by mechanical scanning procedures of a set of individual coils, grouped in a single probe and forming the multi-element coil system. The use of a multi element sensor system makes it possible to control a large surface area and thus reduce the number of particularly time-consuming scans, and to minimise the effect of mutuality between adjacent coils, a multiplexed supply of the elements making up the multi-element sensor is carried out. It is in this context that our work "3D Eddy Current Imaging from Multi-element Sensors in Multiplexed Mode Applied to Multilayer Structures Used in Aeronautics" is situated.
