WebJan 31, 2024 · Argon is used as a shielding gas to keep air out of a welding arc. It’s used in both the primary welding stage and to purge the backside of the joint. ... Gas welding with oxygen also provides a sufficient shield to protect some metals from needing a shielding flux filler wire. Acetylene. Image credit: Cjp24, Wikimedia. For most of its applications gas metal arc welding is a fairly simple welding process to learn requiring no more than a week or two to master basic welding technique. Even when welding is performed by well-trained operators weld quality can fluctuate since it depends on a number of external factors. All … See more 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 See more The three transfer modes in GMAW are globular, short-circuiting, and spray. There are a few recognized variations of these three transfer modes including modified short-circuiting and pulsed-spray.
