Welding of Stainless Steel
We put the air resistance, water vapor and other weak corrosion medium can also prevent rust of steel into stainless steel, in our life, stainless steel is extremely widely used. With the increasing demand for stainless steel in the market and the variety of styles and uses, how can we perfectly meet the needs of users? Stainless steel welding is one of the methods.Before welding ,we should do these things to make the results perfectly:
Usually ,we put welding stainless steel into welded stainless steel and seamless stainless steel.
First, Seamless stainless steel:
The principle of seamless welding is gas shielded arc welding, referred to as gas shielded welding or gas electric welding. It is a fusion welding using arc as heat source and gas as protective medium. During the welding process, the protective gas creates a protective layer around the arc to separate the arc, the molten pool from the air, prevent the influence of harmful gas, and ensure the stable combustion of the arc. Gas shielded welding can be classified according to electrode state, operation mode, type of shielding gas, electrical characteristics, polarity, scope of application and so on.
Advantage of seamless welding is that help eliminate mold weld, but also improve the precision, finish and appearance of parts. At the same time, seamless welding technology in the process of injection molding implementation of efficient control, shorten the mold processing cycle. Due to the excellent surface finish of the products produced by this process, secondary spraying and annealing are not required and the dimensional changes caused by secondary shrinkage are avoided.
Secondly,Seam stainless steel
The welded stainless steel pipe has welding ribs on the inner wall of the welded pipe.Welding stainless steel pipe needs to be rolled after welding, generally spiral welding and direct welding. The tear of welded stainless steel pipe almost always occurs away from the welding point or the heated area. This is because there are fewer impurities in the weld, and the nitrogen content is slightly higher. Because the welding is stronger than the other parts.
