How To Ensure The Quality Of Processing Of Various Weldments

2026-01-31

The quality assurance of welding processing runs through the four core links of raw material control, process execution, process inspection, and finished product acceptance, forming a full process closed-loop control. The specific measures are as follows: 1. Raw material and welding material control - The base material needs to provide Material Certification (MTC), and the main materials such as carbon steel, stainless steel, and aluminum alloy should undergo spectral testing before being stored to ensure that the material grade and composition meet the standards; - The welding materials (welding rods, welding wires, protective gases) should be strictly matched with the base metal (such as stainless steel with stainless steel welding wire, aluminum alloy with argon arc welding special wire). The welding materials should be dried, insulated and stored according to specifications to prevent moisture from affecting the quality of the weld. 2. Standardized process execution - Develop exclusive Welding Process Guidelines (WPS) for different materials, thicknesses, and welding types, specifying parameters such as welding current, voltage, speed, and groove angle; - Welders must hold a certificate (such as a welder qualification certificate) before taking up their posts, and special welds (heavy and ...
