Active gas shielded welding

Use active gas as protective gas. Carbon dioxide is usually used. The gas will decompose in the arc, thus increasing or decreasing the welding range.

Because CO2 is the main gas, MAG welding is usually called CO2 welding.

Features and uses: The main advantage of MIG arc welding is that it can be easily welded in various positions, and it also has the advantages of fast welding speed and high deposition rate. MIGMAW can be used for most major metals, including carbon steel and alloy steel.

Metal inert gas shielded welding

Inert gas shielded welding

Use inert gas as protective gas to avoid reaction with other substances. The inert gas usually uses argon argon or helium helium helium.

Sometimes, a small amount of oxygen, carbon dioxide or H2 is mixed in the inert gas.

Usage: Metal inert gas is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloy. This welding method can also be used for arc spot welding.
