Argon arc welding is a welding technique that uses argon gas as a shielding gas. [1] Also known as argon gas shielded welding. It is to apply argon shielding gas around the arc welding area to isolate the air outside the welding area and prevent oxidation of the welding area.

Argon arc welding technology is a welding technique that is based on the principle of ordinary arc welding, using argon gas to protect metal welding materials. Through high current, the welding material is melted into a liquid state on the welded substrate to form a molten pool, achieving metallurgical bonding between the welded metal and the welding material. Due to the continuous supply of argon gas in high-temperature fusion welding, the welding material cannot come into contact with oxygen in the air, thus preventing oxidation of the welding material. Therefore, stainless steel and iron hardware metals can be welded.
