Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).
GTAW weld area. Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder. Similar to torch welding, GTAW normally requires two hands, since most applications require that the welder manually feed a filler metal into the weld area with one hand while manipulating the welding torch in the other.
C-40 (60% argon/40% CO 2) is used for some flux-cored arc welding cases. Better weld penetration than C-25. C-25 (75% argon/25% CO 2) is commonly used by hobbyists and in small-scale production. Limited to short circuit and globular transfer welding. Common for short-circuit gas metal arc welding of low carbon steel.
Gas metal arc welding Man welding a metal structure in a newly constructed house in Bengaluru, India. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a joining of the metals.

Most aluminium alloys can be joined by welding together; however, certain aircraft-grade aluminium and other special alloys are unweldable using conventional methods. Aluminium is commonly welded with gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). Due to aluminium's oxide layer, a positive polarity is needed to break up the ...
