Argon is used in welding to prevent oxygen from entering the weld site. Oxygen is basicly bad for the weld and Argon displaces the oxygen which results in a better weld (less heat stress, less air pockets (imperfections in the weld) etc.)
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 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.
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.
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
Because argon is an inert gas, don't react with metals.
TIG welding uses Argon.

It is a 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 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".
