The shielded metal-arc ívhegesztésnél (MIG or MAG ívhegesztésként known) electric arc is created continuously pushed for solid wire and the end of the work piece. The arc and the weld melt inert or active gas-jet technology. The procedure most of the material is suitable for the welding of metals for a wide range available. MIG / MAG welding process from the method due to more productive in the MMA than because it reduces the productivity of all cases in which the welding is stopped and a new electrode to the elektródafogóba. In MMA welding, even beyond that material loss is generated, since the end of each electrode should be discarded.

Each kilogram of coated electrodes purchased approx. 65% will become part of the weld (the remaining waste will be). The solid and flux cored wire up to use this efficiency increased up to 80-95%. The MIG / MAG welding is a versatile process that allows the welding material is very good and kihozatallal all welding situations. The procedure is widely used in light-and medium thick materials for steel and an aluminum alloy structures, where the high proportion of manual work is required. The increasing use of flux cored wires for the appearance of a heavy steel case as well.
