How to deal with rusty stainless steel welds?

First, do electrolytic polishing. Stainless steel weld for electrolytic polishing, can improve the weld surface oxidation resistance, because the smaller the surface roughness of the metal, the better the corrosion resistance. And electrolytic polishing after the stainless steel weld surface can produce a layer of dense, uniform protective film to protect the internal metal to reduce the chance of oxidation corrosion.

Second, do pickling passivation treatment. The purpose of pickling is to first clean off the stainless steel weld oxides. The purpose of passivation is to produce a layer of dense oxide film on the metal surface, increase the surface of the ability to prevent corrosion and oxidation.
