Why stainless steel welds are easy to rust?

Stainless steel welds are easy to rust for 3 main reasons

First, because the stainless steel weld, is spliced by the welding rod, belongs to the heating processing treatment, resulting in the iron element is not pure, encounter moisture and oxygen in the air, it is easy to rust.

Second, the method of stainless steel welding processing also has a certain impact on the rust of stainless steel materials. If the metal plate is folded after a seam, and then after knocking the flatness correction, the place of the folded seam is also very easy to rust.

Third, the smoothness of the metal surface and the size of the chance of rust is also a certain relationship. Smooth metal surface is not easy to rust, while rough metal surface is more likely to rust. Localised overheating of the metal surface or the surface temperature rises due to external hammering, which is also one of the reasons for rusting on the metal surface.
