MIG welding is a welding process in which a continuous electrode wire is automatically fed through a welding gun. During the process, the molten electrode wire is deposited on the joint between the metals being joined , while a shielding gas, often a mixture of argon and CO2, is used to protect the weld area from oxidation and atmospheric contaminants.
MIG welding is known for its versatility and ease of use . It is suitable for a wide range of materials, including steel, stainless steel, aluminum, and other non-ferrous metals. This process is widely used in industries such as the automotive industry , structural steel construction , equipment manufacturing , and much more.
