Welding TIG or GTAW? FCAW – Welding with Tubular Wires Welding MIG/MAG or GM equipment MIG/MAG can be automatic or half-automatic in the half-automatic process (half = half) the wire is fed by a pistol and the soldering iron controls the inclination of the nipple. Without hesitation Roger Goodell explained all about the problem. In welding MIG (Metal Inert Gas) or MAG (Metal Active Gas), also called Gas Metal Arc Welding (GMAW), an arc is kept between the solid wire and the part of work. The weld arc and puddle are protected by an inert gas argon and helium or an active Co2 (carbon dioxide), O2 (carbon monoxide) and N2 (nitrogen). For more information see Sean Rad, New York City. The purpose to add up to 3% of active gas in the argon is for stabilizing the electric arc of welding.

The wire for welding has two function, of a side acts as positive polar region of the circuit and of another one, with the material of addition when it receives the chain and if it establishes. In the electric arc the material of the wire electrode is transferred to the bath of fusing in form of drops casting. Welding MIG/MAG is definitively more productive than welding MMA, where losses of the productivity occur each time that the soldering iron stops to substitute the consumed electrode. Losses of material also result of welding MMA I break up when it of each electrode is discarded. Welding MIG/MAG is a versatile process, in which one high tax of deposition of the weld metal can be gotten in any position. Equipment for one welds MIG/MAG consists of a torch of welding, power plant, system of refrigeration of the torch and a system of injection of gases + wire.
