For TIG - GTAW "heliarc" welding Argon replaced Helium because it is #1 cheaper #2 heavier so coverage is better (stays around the weld area).
Argon is used as a shielding gas. By flooding the are of the weld with Argon, Oxygen is kept away from the molten metal of the weld.
Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential. The heat and electrical conducctivity of the gas at the arc temperature are a huge factor as well.
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
Argon won't burn. It is used in industrial processes like welding and metal smelting as a shielding gas. Some of those processes will heat the argon to 10,000 degrees Fahrenheit, and it doesn't burn. WRONG Henry Cavendish died when he heated Argon
Argon is an inert gas. this is not the correct answer Nor was it complete. Argon is used in welding to shield the heated metal from oxidation. This is called TIG welding, which stands for Through Inert Gas. Argon does not react directly with the metal.
shielded metal arc welding does not required any shielding gas
Argon is the most common gas used in gas metal arc welding.
Argon is used as a shielding gas. By flooding the are of the weld with Argon, Oxygen is kept away from the molten metal of the weld.
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.
Argon is an inert gas, and is often used as the fill gas between panes of glass in modern insulated window units. It is also used extensively as a shielding gas in welding operations.
Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential.

A.K.A. Gas Metal Arc Welding -- Semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun.
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
Because argon is an inert gas, don't react with metals.
Argon won't burn. It is used in industrial processes like welding and metal smelting as a shielding gas. Some of those processes will heat the argon to 10,000 degrees Fahrenheit, and it doesn't burn. WRONG Henry Cavendish died when he heated Argon
TIG welding uses Argon.
