In gas tungsten arc welding (GTAW) or tungsten inert gas (TIG) welding, argon gas is frequently utilised. In GTAW, a tungsten electrode and the metal being welded are brought into an electric arc, and the heat from the arc melts the metal and forms a weld. To insulate the weld from ambient contaminants, argon gas is employed. Argon gas rushes out of the welding torch when the arc is struck and forms a shield around the weld to shelter it from air gases like oxygen and nitrogen that could react with the hot metal and lead to weld flaws.Because it is an inert gas that does not react with other substances and is heavier than air, argon gas is used in TIG welding to assist produce a stable shielding environment surrounding the weld.

In gas metal arc welding (GMAW) or metal inert gas (MIG) welding, argon gas is also occasionally utilized, but carbon dioxide or a mixture of argon and carbon dioxide is more frequently employed. Because it is widely accessible, reasonably priced, and good at shielding the weld from ambient pollution, argon gas is preferred in welding applications.
