In the production process of stainless steel storage tanks, welding is a very important link. Stress corrosion cracking of welded joints is a relatively common form of failure, which will affect its quality and sealing effect, making the equipment unable to be used normally. So how to avoid this problem?

1, Reasonably formulate the molding processing and assembly process to minimize cold work deformation, avoid forced assembly, and avoid various scars during the assembly process.

2,stainless steel storage tankAppropriate welding processes are adopted during production to ensure that the welds are well formed and do not cause any stress concentration or pitting defects, such as undercuts, excessive weld heights, contamination of the base metal caused by spatter, etc., to avoid stress corrosion cracking problems.

3. During production, attention should be paid to adopting a reasonable welding sequence to reduce the level of welding residual stress. This is also a good measure to avoid stress corrosion cracking.

Welding is an important step in production and is related to the quality of stainless steel storage tanks. Therefore, it is necessary to master the correct welding method to ensure the welding quality and avoid problems such as corrosion and cracking.
