Description

Technical Field

[0001] The utility model relates to the field of friction stir welding, in particular to a multi-positioning flexible tooling with a cooling mechanism. 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 the workpiece is subjected to friction stir welding, a large amount of heat is generated. The heat is transferred from the weld to the entire workpiece, causing the overall temperature of the workpiece to rise, which is not conducive to the formation of the weld. In addition, the uneven temperature rise of the workpiece may cause slight displacement of the workpiece. Therefore, it is necessary to improve such a structure to overcome the above defects.
