Abstract

The invention belongs to the technical field of friction stir welding, and particularly relates to a thick plate welding stirring head and thick plate welding equipment, and the thick plate welding stirring head comprises a shaft shoulder and a stirring part; the stirring part comprises a first stirring needle and a second stirring needle; the first stirring needle is connected between the shaft shoulder and the second stirring needle, and the first stirring needle, the shaft shoulder and the second stirring needle are coaxially arranged; the needle length and the diameter of the second stirring needle are smaller than those of the first stirring needle, and the connection position of the first stirring needle and the second stirring needle is in step surface transition. By means of the structure, the problem of S lines generated during thick plate welding can be solved, and meanwhile welding defects are reduced.

Description

technical field [0001] The invention belongs to the technical field of friction stir welding, and in particular relates to a thick plate welding stirring head and thick plate welding equipment. Background technique [0002] Friction stir welding refers to the use of heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally melt the material of the welded workpiece. When the welding tool moves forward along the welding section, the plasticized material is under the action of the rotating friction of the welding tool It flows from the front of the welding tool to the rear, and forms a dense solid-phase weld under the extrusion of the welding tool. [0003] The stirring head used for friction stir welding mainly includes a shoulder and a stirring pin, wherein the shoulder is used to provide welding heat source through friction with the surface of the workpiece, and the stirring pin is used to provide heat input through friction wit...
