The necessary inspection of welded joints is an important measure to ensure the quality of welding. Therefore, after the workpiece is welded, the weld should be inspected according to the technical requirements of the product, and the defects that do not meet the technical requirements should be repaired in time. The inspection of welding quality includes three aspects: appearance inspection, non-destructive inspection and mechanical property test. These three are complementary to each other, and non-destructive testing is the main.
