What is the inspection method for welding quality of automobile stamping parts?

Stamping parts manufacturers need to weld some parts of automobile stamping parts. What is the quality of the welding? There are certain inspection methods, so what are the inspection methods? Let's take a look below; 1. Intuitive inspection, use ordinary visual inspection without auxiliary equipment, look at the appearance of the body sub-assembly, the number of solder joints, the location and the quality of forming, etc.; 2. Use and normal production The same welding parameters, for the same material, the same thickness, and the same level of the test plate welding, after the completion of the test, the relevant test report will be issued, and the test report will be submitted to the technical department for archiving; 3. Use special tools or devices to insert the automotive stamping parts After applying an external force at the welding place or between the parts adjacent to the welding seam, observe the forming quality of the welding joint without damaging the components; 4. Professionals use special tools or devices to insert the welding parts of the automobile stamping parts and the adjacent parts The parts of the welding seam are completely separated until the components are completely separated, and then observe the forming quality of the solder joint; Recommended article: How to reduce the problem of surface roughness of stamping parts?
