Description

Gas metal arc (MIG) welding is a welding process that uses a consumable metal electrode and a shielding gas to join metals together.

Overview of Process

This process involves causing a spark between a consumable metal electrode and a metal surface, which causes the surface and electrode to melt and, upon cooling, form a connection between pieces of metal. An inert shielding gas (such as argon or helium) is used to prevent atmospheric contamination of the surface. Gas metal arc welding is a highly-effective welding technique for a wide variety of metals, and has the advantage of easily adapting to various metalworking tasks.
