MIG welding (inert gas metal arc welding)In addition to MIG welding torch with wire instead of the tungsten electrode outside. Like other and TIG welding. Thus, the wire by the arc melting, into the welding area. Power-driven roller in accordance Nickel Alloy Welding Wire with the required welding wire fed from the spool to the welding torch.The heat source is DC arc, but when the polarity used for TIG welding the opposite. The protective gas used is different, argon gas was added to l% oxygen, to improve arc stability.In the basic process is also somewhat different, for example, spray transfer, pulsating spray, globular transfer and short delivery.
