“…The NDT includes various techniques, such as visual testing, liquid penetrant testing, radiographic testing, and ultrasonic techniques [8]. In contrast, eddy current testing (ECT) is the most widely used technique to inspect defaults and flaws using electromagnetic concepts.The ECT was investigated in several studies to detect the existence of flaws in aluminum plates and gas tubes and to determine the superficial flaw's length, width, and depth [10,11,12,13].…”

The flaw propagation angle is a vital factor in the behavioral study of fractures, especially in the case of structures under dynamic or fatigue loading. In this paper, Eddy's current testing has been used with the finite element modeling method to determine the flaw angle for a two-dimensional axisymmetric problem in a gas tube. Moreover, the influence of the flaw angle on the sensor impedance during the scanning process is carried out. On the other hand, the inverse problem is optimized using one of the most recent and effective metaheuristic optimization algorithms called Grey Wolf Optimizer (GWO).It allows for defining an optimized relationship between the flaw angle and the sensorimpedance. Simulations are carried out to validate the proposed approach and show its efficiency in accurately determining the flaw angle.

“…However, it was also necessary to provide for the installation of thermocouples in the underside of the welding cord of the sheets in order to obtain a reference measurement. Thermal imaging is successfully used as a diagnostic technique in many areas such as ceramics composite materials and metals [7][8][9][10]. In this work, this technique is used to make analysis of the cord and to assess the quality of the welding even before performing an analysis of the micro and macro-mechanical properties of the joint.…”

IIn this work, the heating distribution on similar and dissimilar friction stir welded joints in aluminium and magnesium alloys sheets was studied. Friction Stir Welding processes were performed using constant rotational and welding speeds of 1500 rpm and 60 mm/min, respectively. In order to obtain a completely non-intrusive and temperature monitoring measurement technique, a contactless method based on infrared thermography was used to remotely analyse the temperature distribution over the welded area, near the tool during the Friction Stir Welding process. It was observed that the mechanical properties of joints are strictly related to the heat distribution. This system was used both to experimentally evaluate the temperature on the top surface of the joints and as it is able to detect the presence of flow defects with a contactless and non-destructive method, demonstrating the effectiveness of this measuring system as a diagnostic tool for the online quality control of welded joints.

“…Nowadays, enterprises are using alternative NDT techniques such as ultrasonics and Eddy current. These methods are more efficient since they are suitable for internal defects and have high sensitivity [4]. Each manufacturing company has its own inspection needs, which determine the necessity of a particular NDT test.…”

Non-Destructive testing is an effective analysis technique that manufacturing firms use to assess the structure and properties of materials. In simple words, NDTs can help inspectors detect irregularities, external and internal defects without causing damage to the original material. The sole purpose of the study is to propose the most convenient method of NDT for small and medium manufacturing businesses. For this reason, we have critically investigated the economic prospects and effectiveness of different NDT methods that can minimize the investment of SMEs in the long run. The proposed method of inspection is cost-effective and efficient enough to detect surface and subsurface cracks in materials. The recommended automated visual inspection in this study requires a small database and low-cost equipment such as cameras and scanners to identify surface and subsurface irregularities. However, it does not require huge initial setup and maintenance costs as compared to Ultrasonic and Eddy Current testing. The automated setup in visual inspection is the best NDT method that SMEs can adopt to reduce manufacturing defects. In addition, this can save a substantial amount of time and effort for inspectors. Therefore, in contemporary manufacturing operations, Dye penetration and AVI are essential to meet the quality standards of products while minimizing overall cost and timeframe.
