AI Technical Summary
Existing single-tungsten electrode single-wire welding torches have low welding efficiency, narrow weld formation, and poor material preparation flexibility, making it difficult to meet the needs of mass production, high-efficiency production, and welding of special performance alloy layers.
The structure employs a dual-tungsten electrode and dual-wire feeding mechanism working in tandem. The two tungsten electrodes simultaneously generate an electric arc to form a composite heat source, while the dual-wire feeding mechanism simultaneously feeds in two welding wires, achieving efficient heat input and material mixing.
It significantly improves welding speed and heat input efficiency, increasing welding speed by more than 50% under the same parameters. It is suitable for large-area, high-volume operations and can flexibly mix two welding wire materials to adapt to different process requirements.
