Introduction MIG (Metal Inert Gas Welding) or Inert Gas Welding. In the process the electrodes are melted and mixed with molten parent metal to form a weld pool. Thus‚ the electrode must be supplied constant current throughout the welding process is carried out. For a continuous supply of electrodes‚ the electrodes are made in the form of wire to be extended out from the nozzle welder automatically at a specified speed. Protective gas is supplied through the nozzle weld as is done in TIG welding
