    en.wikipedia.org/wiki/Gas_metal_arc_welding

    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).

    This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

  4. Lugged steel frame construction - Wikipedia

    However, recent advances in metallurgy have created steel tubing that is not adversely affected (or may even be improved) by high temperature welding. This has allowed both TIG and MIG welding to displace lugged steel construction, [8] [unreliable source?] in large part because these methods lend themselves more easily to automation and reduce ...

  6. Gas tungsten arc welding - Wikipedia

    en.wikipedia.org/wiki/Gas_tungsten_arc_welding

    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.

  9. Shielding gas - Wikipedia

    en.wikipedia.org/wiki/Shielding_gas

    Other arc welding processes use alternative methods of protecting the weld from the atmosphere as well – shielded metal arc welding, for example, uses an electrode covered in a flux that produces carbon dioxide when consumed, a semi-inert gas that is an acceptable shielding gas for welding steel.
