The welding part 40 is movably arranged on the base body 10, and the welding part 40 is used to weld the workpiece 01 to be welded.

[0037] By applying the technical solution of the utility model, the automatic flipping of the workpiece 01 to be welded can be realized by setting the lifting part 20 and the flip assembly 30, and the welding part 40 can be movably arranged on the base 10, so as to realize the welding of the workpiece 01 to be welded. In the traditional technical solution, the workpiece 01 to be welded is usually flipped manually by the staff, especially when the workpiece 01 to be welded is a beam body, the efficiency is low and the labor intensity is high. Compared with the traditional technical solution, the setting of this solution can realize the flipping of the workpiece 01 to be welded through the cooperation of the lifting part 20 and the flip assembly 30, which is efficient and reduces the labor intensity of the staff. When the workpiece is flipped, the first clamping part 32 clamps the workpiece 01 to be welded. After the first clamping part 32 clamps the workpiece 01 to be welded, the lifting part 20 descends, so that a space for flipping the workpiece 01 to be welded is formed between the lifting part 20 and the workpiece 01 to be welded, and the flip part 31 drives the first clamping part 32 to flip the workpiece 01 to be welded, and then the lifting part 20 rises to support the workpiece 01 to be welded.
