What Is Argon Gas Welding

Argon is a welding shielding gas that enhances arc stability and prevents atmospheric contamination of welding pools. Argon is essential to gas tungsten arc welding (GTAW). It also prevents oxidation during metal production.

What kind of welding uses argon?

Argon is the most commonly used inert gas for TIG welding projects. Since only a few gases can be used for TIG welding, argon is the most popular choice because it’s a versatile gas that can be used on a variety of metals including mild steel, stainless steel, and aluminum.

What is the difference between MIG gas and argon?

TIG Welding requires pure Argon gas, which produces a clean weld with no oxidisation. MIG Welding requires an Argon-CO2 mixture for higher penetration and heat. The purpose of the gas in the MIG process is to protect/shield the wire, the arc and the molten weld metal from the atmosphere.
