Because argon is an inert gas, don't react with metals.
For example argon or helium for TIG welding. Oxi-fuel welding: oxygen and a combustible gas: acetylene, propane, butane, propylene, gasoline, hydrogen, etc.
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.
Argon is an inert gas, hydrogen is not. Hydrogen is flammable and would negatively impact the arc process.
Neon and argon are used as a gas starter in sodium lamps.
In its natural form, argon is a gas, not a mineral!
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
TIG welding uses Argon.
It is a gas.
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.
argon gas
Argon is an inert gas. At the high temperatures which are reached during welding the metals involved can get highly reactive. An inert environment prevents chemical reactions.
When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
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.
Argon is an inert gas. At the high temperatures which are reached during welding the metals involved can get highly reactive. An inert environment prevents chemical reactions.
Argon is the most common gas used in gas metal arc welding.
As an inert gas, it shields the weld from oxygen and corrosion during the melting process. Tig welding means "through inert gas".
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
