What is MIG welding?

What does MIG stand for in Welding? MIG stands for metal inert gas.

MIG is one of the easiest welding processes to learn. Most people can learn to run good beads with MIG in just a few hours. This article only explains the term.

When did MIG start?

MIG came about during World War II. It was developed to help produce weapons and equipment faster. It was then used in the post-war booming economy, mostly in shops and factories.

Metal inert gas welding

In MIG, a spool of solid-steel wire is fed from the machine, through a liner, then out of a contact tip in the MIG gun. The contact tip is hot, or electrically charged, when the trigger is pulled and melts the wire for the weld puddle. This is accomplished in several ways.

MIG usually is carried out inside fabrication shops and factories, because out in the field, the wind displaces the shielding gas, which, ironically, is there to displace the wind.

MIG can be used in the field. However, wind blocks, usually made of plastic sheets, must be built around the welder as protection.

MIG at Home

What’s neat about MIG is that you can put a machine in your garage and weld up a storm. MIG welding is very popular, because it is easily learned and because you can do and make many things with it. In adult education classes, people learn MIG so they can do everything from making outdoor art to restoring classic cars.
