Argon

Argon is commonly used as an inert shielding gas in welding processes, such as Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW).

It is used to protect the weld area from atmospheric gases, like Oxygen, Nitrogen, and water vapor, which can negatively affect the weld quality or make the welding process more challenging.

Argon is also utilized for creating inert atmospheres in various applications such as filler gas in incandescent and neon lamps, where its inertness helps prolong the lifespan of the filament.

Additionally, in plasma cutting, Argon is often mixed with Hydrogen to create a stable arc for precise cutting. Argon finds applications in gas chromatography, where it acts as the carrier gas to transport samples through the chromatographic column and spectrometry techniques to create the necessary environment for accurate analysis.
