“…Therefore, acoustic emission testing is only a supplementary means of detection and cannot replace the traditional detection method. Ultrasound cannot achieve high-quality imaging [28][29][30][31]. Eddy current flux leakage spot welding detectors can only detect surface defects, and the cost is high [24,25].…”

Using the traditional magneto-optical detection methods, micro-weld defects parallel with the magnetic field direction may be overlooked. In order to overcome this, a non-destructive testing method based on magneto-optical imaging under a vertical combined magnetic field (VCMF) is proposed. To demonstrate this, the experimental results of the magneto-optical imaging of weld defects excited by a vertical combined magnetic field (VCMF) or parallel combined magnetic field (PCMF) are compared with those of traditional magnetic fields (constant magnetic field (CMF), alternating magnetic field (AMF), and rotating magnetic field (RMF)). It is found that the magneto-optical imaging under a VCMF can accurately detect weld defects of any shape and distribution. In addition, the center difference method is used to eliminate the influence of noise on the defect contour extraction of magneto-optical images, and the active contour of weld defects in the magneto-optical images is extracted. The results show that many noises can be identifiedby the robustness of the level set method, operating in low-pass filtering, so that much information that is usually lost can be retained.

“…Currently, non-destructive tests have become an indispensable and necessary tool in the industry, being the primary means for determining the level of quality achieved by different products [1]. In the area of industrial manufacturing such as metal parts, construction of structures, assembly of parts in industrial plants, it is necessary to carry out evaluations and diagnostics in the existing welded joints, in addition the welding process must be the most suitable and suitable for the fusion of the base material [2,3]. In addition, the welding process must be the most suitable and suitable to meet the objective, which translates into obtaining a union, which meets the conditions required by the standards, codes and specifications already established [4].…”

This work is based on making a comparison of different inspection methods of non-destructive testing (NDT), to detect porosity, bite, undercut, splash, overlap, slag, concavity, lack of fusion and damage to base material, in welds of shielded metal arc welding (SMAW) and flux-cored arc welding (FCAW), made on a steel bridge ASTM-A-588. The main application of non-destructive tests is to evaluate the final state of a welded joint in critical points, in addition the fundamental objective is to ensure that the established acceptance and rejection criteria are met rigorously. For which non-destructive techniques are analyzed, such as the visual testing of welding on the beams of a bridge of length 35000 mm, subsequently, tests of inspection by liquid penetrant were used, based on the AWS D1.5 standard to confirm the failures in welded joints in ABA webs, an ultrasonic is also carried out using an SIUI CTS 602 equipment, finally to issue an acceptance and rejection criterion as determined by ASTM E165 and ASTM E2544-09.
