By providing a docking clamping mechanism 3 and clamping the workpiece with the moving component 39, during welding, the driving component 37 is used to drive the rotation and cooperate with the clamping workpiece to realize the synchronous rotation of the two clamping plates 36, so that the transmission gear 38-2 moves in the vertical direction along the limiting rack 38-1, so that the workpiece can be turned over without removing it, and the problem of collision between the workpiece and the workbench when turning the workpiece is avoided, thereby effectively improving the efficiency of butt welding.

The welding assembly 2 includes a bracket installed on the top of the processing table 1, and a welding head installed on the bracket, so that the welding head is aligned with the center line of the butt welding, and the welding head realizes the welding operation through the existing laser welding.
