A first threaded rod 220 is threadedly connected to the sliding plate 222, and a handwheel 223 is fixedly connected to one end of the first threaded rod 220.

[0031] Furthermore, a top rod 219 is fixedly connected to the other end of the first threaded rod 220, and an elastic anti-slip head 221 is fixedly connected to one end of the top rod 219. The elastic anti-slip head 221 is connected to the surface of the horizontal tube 207 to fix the sliding plate 222 and the limiting plate 218.

[0039] After clamping is completed, the welding mechanism 1 is started. The operator or the control system controls the robotic arm 101 to move to the predetermined welding position. The welding head 102 starts to work. The welding module 103 provides the necessary power support. According to the preset program, the robotic arm 101 drives the welding head 102 to move along the weld path to complete the welding process. After welding is completed, the clamping assembly 203 is reversed to release the clamping head 214, remove the welded steel structure, and then reset to prepare for the next operation.
