A MIG welder is a staple at most welding shops, as it is here at Dwyer Manufacturing.
Here’s a brief history of MIG welding:
Metal Inert Gas (MIG) welding is a welding process in which an electric arc forms between a consumable wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to melt and join.
Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air.
Originally developed for welding aluminum and other non-ferrous materials in the 1940s, MIG welding was soon applied to steels because it provided faster 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 became common. Further developments during the 1950s and 1960s gave the process more versatility and as a result, it became a highly used industrial process. Today, MIG is the most common industrial welding process, preferred for its versatility, speed and the relative ease of adapting the process to robotic automation. Unlike welding processes that do not employ a shielding gas, such as shielded metal arc welding, it is rarely used outdoors or in other areas of air volatility.
Most of us have seen a welder operate, but have you seen it in super slow motion?
