Technical Field
[0001] The invention relates to the field of friction stir welding, and in particular to a cantilever friction stir welding device. Background Art
[0002] Friction stir welding refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to partially melt the material to be welded. When the welding tool moves forward along the welding interface, the plasticized material flows from the front to the back of the welding tool under the action of the rotating friction force of the welding tool, and forms a dense solid phase weld under the extrusion of the welding tool.
[0003] When welding special-shaped workpieces such as arc-shaped workpieces and bent workpieces, since the welds are not on the same plane, the placement of the workpiece needs to be adjusted during welding. However, since the center of gravity of the special-shaped workpiece is not completely in the middle, changing the placement of the workpiece may cause the workpiece to tip over, thereby damaging the workpiece and making it inconvenient to weld the workpiece. Summary of the invention
