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. Keywords: Eddy current testing, multiplexing, eddy current array, imaging defect.

Inspection of aluminum sheets using a multi-element eddy current sensor: 2d and 3d imaging of surface defects of various sizes and internal defects at various depth
In the industrial sector, ensuring reliability and durability is of paramount importance. Our research aims to advance beyond conventional non-destructive testing methods by focusing on thorough defect detection and imaging. We utilize advanced, sensor-enhanced eddy current testing, featuring multiple elements arranged in a cutting-edge serial array. This innovative configuration addresses the issue of magnetic repulsion between sensor elements, thereby speeding up the testing process and ensuring precise results through both 3D and 2D imaging. This sophisticated approach allows us to more effectively characterize defects of varying sizes and depths in aluminum sheets. By meticulously collecting and analyzing data from the sensors, we can identify the appearance and nature of these defects with greater clarity. Our findings introduce a pioneering method for defect detection, highlighting the efficacy of our advanced testing technique. Our research underscores the potential of multi-element eddy current sensors in revolutionizing the inspection process. The ability to produce detailed 3D and 2D images of surface and internal defects represents a significant leap forward in non-destructive testing. This comprehensive imaging capability not only accelerates the detection process but also enhances the accuracy and reliability of defect characterization. By employing this state-of-the-art technology, we can detect even the smallest and most deeply embedded defects that traditional methods might miss. The precise imaging provided by our approach ensures that defects of various sizes and depths are accurately identified and characterized. This level of detail is crucial for maintaining the structural integrity and performance of aluminum sheets used in industrial applications. Our research demonstrates a groundbreaking approach to defect detection in aluminum sheets, leveraging the advanced capabilities of multi-element eddy current sensors. The innovative use of a serial array of sensors, combined with sophisticated data analysis techniques, allows for rapid, accurate, and detailed imaging of defects. These findings pave the way for improved reliability and durability in industrial applications, setting a new standard for non-destructive testing. Keywords: Eddy Current Testing. Multi-Sensors.

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.

Scanning by multi-sensors to detect surface and internal defects
this research paper aims to detect of hidden defects on a metallic plate by collecting data by placing several eddy current sensors side by side. With alternating feeding in order to avoid mutual induction between different sensors. This technique saves a great deal of time when evaluating conductive elements with a small number of tests that allow us to obtain a signal from which we know the presence of an internal defect, and thus pave the way for us to determine their shape and dimensions in other works.

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.
