[0002] A weld refers to the area where two or more workpieces are joined together during the welding process by heating, pressure application, or both. The quality of the weld is directly related to the strength, sealing performance, and reliability of the welded structure. During the welding process, it is necessary to strictly control the welding process parameters to ensure that the quality of the weld meets the requirements. After welding is completed, it is necessary to promptly detect the weld to timely discover defects in the weld and ensure the safety and reliability of the welded structure.

[0003] Currently, the detection of the welds of welded parts after welding is usually directly observed by inspectors with the naked eye to check the appearance of the welds, such as the shape, size, and surface quality of the welds. The main thing is to check whether the welds are flat and smooth and whether there are obvious defects such as cracks. However, visually inspecting the welds requires spending a lot of time checking point by point, with low efficiency, and visually inspecting and measuring the dimensions require the use of some complex measuring tools and equipment, and the operators need to have certain professional skills.
