Helium is inert and the least soluble of all gases in liquids and is therefore used as a pressurization. Being inert, helium is used as a constituent in neutral atmospheres e.g., in heat treatment applications requiring a protective atmosphere.
Helium is used extensively in the welding industry as an inert shielding gas for arc welding. It is also used in conjunction with helium (“leak”) detectors to test the integrity of fabricated components and systems.
