Description

Technical Field

[0002] Argon arc welding is a welding technology that uses argon as a shielding gas, also known as argon gas shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area. Argon arc welding technology is 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 welded substrate to form a molten pool, so that the welded metal and welding materials can achieve metallurgical bonding. Because argon is continuously supplied during high-temperature molten welding, the welding materials cannot contact with oxygen in the air, thereby preventing oxidation of the welding materials. Therefore, stainless steel and iron hardware metals can be welded. With the development of society, argon arc welding sleeves are used when barbells need to support barbell plates.
