Final answer:

Argon, Helium, and Carbon dioxide are commonly used gases in various welding processes.


Explanation:

Argon is commonly used as a shielding gas in MIG welding to protect the welding arc and base metal from the atmosphere. It creates an inert gas shield during welding, flushes out melted metals to eliminate porosity, and provides an oxygen- and nitrogen-free environment for metalworking processes.

Helium is often used in cryogenics for maintaining superconductors at extremely low temperatures and as a carrier gas in gas chromatography.

Carbon dioxide is also commonly used in welding processes but not as frequently as argon. It can be used in a mix with other gases to achieve specific welding results.
