A welding positioning device is required in the welding process of steel bars. However, the welding positioning device for steel bars needs to recover the welding flux after each welding, which wastes time and reduces welding efficiency. In addition, the positioning device can only perform concentric and coaxial positioning and clamping of two steel bars. It cannot perform clamping when non-concentric and coaxial welding of two steel bars is required.
