http://alcotec.com/us/en/education/knowledge/qa/What-shielding-gas-should-I-use-when-welding-aluminum.cfm WebCNC Gas tungsten arc welding machine (GTAWM), also known as tungsten inert gas (TIG) welding machine, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium).
Web7 dec. 2024 · The two most commonly used inert (noble) shielding gases used to weld aluminum are Argon (Ar) and Helium (He). Argon or a combination of argon and helium are used to almost the exclusion of all other gases when welding using gas metal arc welding GMAW (MIG), or gas tungsten arc welding GTAW (TIG), processes.
