Mig Welding

MIG (Metal Inert Gas) welding is a metal joining process. In contrast to MAG (Metal Active Gas) welding, MIG welding uses argon or another inert gas as a shielding gas, although the two terms are often used interchangeably. Direct Current is applied to a consumable electrode, spool fed at a controlled rate through the welding gun. This creates an arc between the electrode and the workpiece. This arc provides the thermal energy necessary to melt the surrounding area, creating a weld pool that solidifies upon removal of the arc to fuse the metal together. Shielding gas is applied through the gun and surrounds the electrode and immediate area to prevent undesirable oxidation of the molten metal with the atmosphere. MIG welding is a versatile process and can be used to effectively join a variety of metal alloys. It requires only limited skill to master when compared to other welding techniques and adapts easily to automation.
