Stress corrosion and cracking of welded joints of stainless steel mixing tanks are its more serious failure forms, which will not only affect the quality of the equipment, but also interfere with the use of the equipment by people. Therefore, measures are needed to prevent the occurrence of this problem.
1. Adopt appropriate welding process in the production to ensure that the welding seam is well formed, and there will be no defects due to stress concentration or pitting such as undercut, excessive welding seam height, and pollution of the base metal caused by splashing.
2. Reasonably formulate the forming process and assembly process, it is necessary to reduce the deformation of cold work as much as possible, avoid forced assembly, and prevent scars caused during the assembly process.
3. In the process of making stainless steel mixing tanks, attention should be paid to adopting a reasonable welding sequence.
Avoiding intergranular corrosion during the production of stainless steel mixing tanks can ensure the quality of welding, and it is also the premise to ensure the overall quality of the equipment. Therefore, various measures need to be taken to prevent it during welding.
