Metal Inert Gas (MIG) welding operates on the same principle as welding with covered electrodes, but using a continuous electrode in the form of solid wire or cored wire strip wound on a reel. It is the most common industrial welding process. It can be used to weld a wide variety of metals and alloys, including aluminum, copper, magnesium, nickel, and many of their alloys, as well as iron and most of its alloys.
