[0002] Argon arc welding technology is a welding technology based on the principle of ordinary arc welding. It uses argon gas to protect metal welding materials. Through high current, the welding materials are melted into liquid on the base material to form a molten pool, so that the metal to be welded and the welding materials can achieve metallurgical bonding. Because argon gas is continuously supplied during high-temperature molten welding, the welding materials cannot come into contact with oxygen in the air, thereby preventing oxidation of the welding materials. Therefore, stainless steel and iron hardware metals can be welded.

When in use, the metal plate to be welded is placed between the multiple clamping plates, and the metal plate is clamped and fixed by the multiple clamping plates to prevent welding deviation.
