With the joint cooperation of the threaded rod 52, the cross beam 4, the slider 55, and the guide rod 54, the nut seat 53 can move along the length direction of the threaded rod 52, thereby driving the cross beam 4 and the mechanisms on the cross beam 4 to rise and fall. When the cross beam 4 is in the appropriate position, the operator places the pipe fitting between the two clamping plates 73, and uses the pushing cylinder 74 to push the clamping plates 73 to clamp and fix the pipe fitting. Then, the transverse movement motor 65 is used to drive the rotation of the bidirectional lead screw 63. The lead screw nut 64 can move along the length direction of the bidirectional lead screw 63 under the joint cooperation of the bidirectional lead screw 63 and the installation groove. The two lead screw nuts 64 approach each other, causing the welding joints of the two pipe fittings to fit together. During welding, the rotation motor 71 is used to drive the rotation of the mounting bracket 72, enabling the pipe fitting to rotate one full circle, facilitating the operator to weld around the welding joint of the pipe fitting.
