When welding corrosion-resistant steels, such as stainless steels, the heated zones adjacent to the weld bead are subjected to oxidation by atmospheric oxygen. They then lose their corrosion resistance.
Inerting is a procedure whereby the ambient oxygen around a welding zone is expelled and replaced by an inert gas, such as argon, to prevent corrosion of the high-temperature heated surface.
