What is Mig Welding?

Gas metal arc welding, also known as Metal Inert Gas MIG welding, is a semi-automatic or automatic welding process. As the weld is laid, MIG wire is fed through the torch along with a shielding gas. Direct current is used to form an electric arc, causing the metals to heat up and melt so they can be joined together.

MIG Welding is used in the construction and idustrial environment primarily to weld iron and steels (including stainless steel); it is also used extensively in the construction of steel structures and in industrial fabrication.
