[0022] The effect achieved by the entire embodiment 1 is that the steel pipe rod placed on the receiving component 5 can contact the surface of the belt 503. When the roller 501 drives the belt 503 to move, the steel pipe rod can be driven to rotate. The sliding bracket 2 can move arbitrarily in the horizontal direction, and the flange to be welded can be tightly pressed between the welding end of the steel pipe rod and the turntable 3. With the cooperation of the turntable 3, the aligned steel pipe rod and the flange can be rotated together, which is convenient for the welding gun 4 to weld the connection.
