AI Technical Summary
Existing TIG welding torches are complex to operate during the welding process, especially in robotic welding where they are low in precision and bulky, difficult to move on curved paths, and require an independent cooling system, which increases their size and complexity.
The converging nozzle design allows external gas to adhere to the outer surface of the electrode and supply protective gas to the arc area, while welding wire is transported in the inner pipe, simplifying the welding operation. The shape and heat flux of the arc can be adjusted through independent gas flow control.
It achieves a compact design for the welding torch, simplifies operation, improves welding accuracy and process control, reduces equipment wear, and is suitable for both manual and robotic welding.
