Gas Metal Arc Welding (GMAW)

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. Some methods of this process are called MIG (Metal Inert Gas) or CO2 welding. MIG welding requires the use of an inert shield gas.
