Protection, Processes, and Positioning: Shielding gases used in stainless steel welding.

The metals in stainless steels like to oxidize (when iron oxidizes, we call it rust). The chromium in stainless steel has a relatively high potential to oxidize, which is why it is added to stainless steel. This oxide forms a protective coating on the outer surface, preventing further oxidation of the material beneath the oxide layer. When welding, the metal experiences a liquid stage, and if oxidation of the liquid occurs, this oxide forms impurities within the weld. Further
