The second screw 22 is then rotated to drive the clamping box 20 to translate, so that the flange contacts the end of the pipe, and then the upper half of the flange in contact with the pipe is welded by welding equipment. When the lower half of the flange in contact with the pipe faces downward and is inconvenient to weld, the third screw 1302 can be loosened, and the straight rod 23 can be turned to loosen the clamping of the two arc-shaped clamping plates 28 on the flange. Since the flange is half welded to the end of the pipe, the flange will not fall off. Then the pipe is rotated so that the lower half of the flange in contact with the pipe faces upward, and then the third screw 1302 is tightened to fix the position of the pipe and continue welding.
