Description

TECHNICAL FIELD

[0001] The utility model relates to flat wire motor welding technical field, especially in a kind of twist head end single robot double-gun TIG welding. BACKGROUND

[0002] Inert gas shielded arc welding, referred to as TIG welding, also known as GTAW tungsten argon arc welding, uses high-melting-point metal (pure tungsten, tungsten-thorium, cerium tungsten, etc.) as a non-melting electrode of arc, and inert gas as arc medium and protective gas, so that arc and welding pool are not affected by the surrounding air. Currently, manual argon arc welding is commonly used. Manual argon arc welding has good directivity and can be welded in all positions.

[0003] The disadvantages of manual argon arc welding are: low welding efficiency, high skill requirement for welders, need for inert gas protection, poor wind resistance, high current density, ultraviolet radiation generated by arc is about 5-30 times that of ordinary electrode arc welding, infrared radiation is about 1-1.5 times that of electrode arc welding, ozone content generated during welding is high, which causes greater harm to human body, and only one welding point can be processed at the same time with a single welding gun, and the beat is low.
