CO2 welding, also known as MAG welding or Gas Metal Arc Welding (GMAW), is a welding process that uses carbon dioxide as the shielding gas.It is a relatively cheap method as CO2 gas is inexpensive.This type of welding can be used on various metals such as mild steel, stainless steel, and aluminum.However, it is not suitable for inert or precious metals.The welding process for CO2 welding is similar to MIG welding, and the same welding machine can be used.
