The zinc volatilizes and leaves the base metal adjacent to the weld.
You increase the risk of your weld cracking and breaking.
Stainless steel s corrosion resistance is due to a thin chromium rich transparent oxide film on the surface 1 this protective film develops when more than 10 5 percent of chromium is present in the alloy and when the gas or liquid environment the stainless steel is exposed to provides oxygen to its surface.
