The American Welding Society (AWS), Miami, FL, refers to Metal Inert Gas (MIG) welding as GMAW, standing for Gas Metal Arc Welding
The gas metal arc welding
(GMAW) process used to connect the sheets together involved continuous feeding of solid wire to an electric arc created between an electrode and the workpiece.
Manufacturers are also meeting rising productivity demands, augmented by the dearth of welding-related labor, by using hybrid technologies such as gas metal arc welding
(GMAW)-laser and niche technologies such as orbital TIG and friction stir welding.
Welding methods are restricted to shielded metal arc welding (SMAW), gas metal arc welding
(GMAW), or flux core arc welding (FCAW).
In the Gas Metal Arc Welding
(GMAW) process, a constant supply of the consumable electrode is maintained through the centre of the welding nozzle.
Gas metal arc welding
(GMAW) is acknowledged as a process that is both easy to operate outside workshops and very economical.
Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding
(GMAW/MIG), Shielded Metal Arc Welding (SMAW/"stick"), Submerged Arc Welding (SAW), Electric Resistance Welding (ERW) and Laser/Hybrid Laser-Assist Welding.
The 89 skill standards are categorized into these 11 areas: analysis (5 standards); setup (11); material preparation (7); shielded metal arc welding (17); gas metal arc welding
(10); flux core arc welding (7); submerged arc welding (2); gas tungsten arc welding (14); surface welding (1); quality assurance and documentation (8); and automated and mechanized welding (7).
For this project, the automatic, low-hydrogen gas metal arc welding
(GMAW) superceded the use of conventional stick welding to join the 40-foot pipe joints.
