CO2 gas shielded welding (MIG) metal active gas welding MAG (metal active-gas welding) welding process A MIG arc welding shielding gas commonly used are: argon, helium, CO2 Gas Shielded Welding Wire these gases. Argon Gas or helium gas is known to protect the metal inert gas shielded arc welding (referred to as the international MIG welding); with inert gas and oxidizing gasBody (O2, CO2) gas mixture for the protection of gas, or CO2 gas or CO2 + O2 gas mixture for the protection of gas, referred to as metal active gas protectionArc protection (referred to as the international MAG welding). MIG arc welding is the main advantage of a variety of locations can be easilyWelding, but also has a fast welding speed, deposition rate and so on. Metal active gas shielded arc welding applied to most of the majorMetals, including carbon steel, alloy steel. Metal inert gas welding for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. UseThis welding method can also be arc spot.
