DUAL SHIELD TORCH NOZZLE FOR WELDING

摘要

The present invention relates to a dual shield torch nozzle for welding and, more specifically, relates to a dual shield torch nozzle for welding capable of easily and stably coupling and decoupling components by coupling and decoupling the components formed of a screw tightening method with a rotary coupling method in consideration to workability and stability. The dual shield torch nozzle for welding comprises: a gas diffuser to jet CO_2 gas through a primary and a secondary gas outlet; a welding tip coupled to the bottom of the gas diffuser to weld an object by combusting the jetted CO_2 gas; an insulator coupled to the gas diffuser above the secondary gas outlet of the gas diffuser to prevent welding heat from being transferred to a torch body; an inside nozzle coupled to the gas diffuser below the secondary gas outlet of the gas diffuser to surround the outside of the primary gas outlet, and spraying CO_2 gas jetted from the primary gas outlet to the outside; and an outside nozzle coupled to the insulator to simultaneously surround the outside of the secondary gas outlet of the gas diffuser and the outside of the inside nozzle, spraying the CO_2 gas jetted from the secondary gas outlet through a gap between the inside and the outside nozzles to the outside.
