Metal Inert Gas (MIG) Welding

An arc welding process wherein coalescence is produced by heating with an arc between a continuous filler metal (consumable) electrode and the work. Shielding is obtained entirely from an externally supplied gas, or gas mixture. MIG welding requires the use of an inert shield gas.
