Argon

Argon is widely used in the metal cutting industry because argon is an inert gas that do not react. Therefore using argon as a gas cover during welding to prevent Work pieces exposed to air Which these parts may react with oxygen in the air or pull oxygen into the work surface, which will make the welding work to be of poor quality. Argon has low ionization energy
thus helping to stabilize arc quality and stability Argon is used as a gas to cover both gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW).
