* MIG Welding - Metal inert gas is a welding process in which an electric arc forms between a consumable MIG wire electrode and the base metal, which heats the base metal, causing them to melt and join. Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air.
