The friction stir welding technology is characterized in that a welding tool is driven to synchronously rotate through high-speed rotation of a machine shaft, slowly pricks into a workpiece to be welded and moves along the position of a to-be-welded seam, and the material around the welding tool is plasticized and connected through the friction heat of the welding tool and the material to be welded serving as a welding heat source. The friction stir welding technology has the advantages of high welding quality, energy conservation, environmental protection and the like, and is widely applied to the fields of aerospace, rail transit, automobile manufacturing and the like.
