About MIG Welding
Metal Inert Gas (MIG) Welding
Also referred to as GMAW (Gas Metal Arc Welding) or short circuit transfer, MIG is a welding process that joins metal by heating them with an arc, shielded by externally supplied shielding gas such as CO2. When welding carbon steel, a gas mixtue of CO2 and argon is commonly used. Metal is deposited when the wire actually touches the workpiece; it is not transferred over the arc.
Semi-Automatic MIG Welding
In this welding process, the welding equipment controls the electrode wire feeding speed and the amperage while the gun movement is controlled by an operator's hand.
Automatic MIG Welding
In this process the welding equipment uses sensing devices to control joint alignment. Most commonly all welding operations are controlled and initiated by automated means.
Robotic MIG Welding
In this process an industrial production operation uses one or more robots, controllers, positioners, and other equipment to make a programmed series of welds on a weldment.
Applications
Construction, repair and maintenance, power generation, aircraft, aerospace, automotive and special interest auto, marine, sporting equipment etc. Process can be manual, semi-automatic or robotic.
