seamless welding

- Sep 24, 2020-

The principle of seamless welding is gas-shielded arc welding, gas-shielded welding or gas-electric welding. It is a fusion welding that uses arc as a heat source and gas as a protective medium. During the welding process, the shielding gas creates a gas protection layer around the arc, which separates the arc and molten pool from the air to prevent the influence of harmful gases and ensure the stable combustion of the arc. Gas shielded welding can be classified according to the state of the electrode, operation mode, shielding gas type, electrical characteristics, polarity, and scope of application.
