Product & Technology News
- Sometimes referred to by its subtypes metal insert gas (MIG) welding or metal active gas (MAG) welding, is a semiautomatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas fed through a welding gun
- A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used
- There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed spray, each of which has distinct properties and corresponding advantages and limitations
- Originally developed for welding aluminum and other non-ferrous materials in the 1940s, GMAW was soon applied to steels because it allowed for lower welding time compared to other welding processes
- The cost of inert gas limited its use in steels until several years later, when the use of semi-inert gases such as carbon dioxide.
