Problems solved by technology

However, in the actual production process, it is difficult to disassemble after the stirring pin is broken or worn (collectively referred to as damage), and there is no set of methods in the prior art that can realize the disassembly after the stirring pin is broken, and the welding tools after the breaking of the stirring pin can only be completely discarded, did not effectively reduce costs

Abstract

The invention discloses a method for disassembling a split friction stir welding tool. The friction stir welding tool includes a shaft shoulder and a damaged stirring pin matched with the shaft shoulder. Materials to be welded are bonded to the surface of the shaft shoulder. The method includes the following steps: S1, removing the material to be welded on the surface of the shaft shoulder; S2, fixing the shaft shoulder; S3, performing surfacing welding on the outer end surface of the damaged stirring pin to form a surfacing layer ; S4, clamping the surfacing layer to take out the damaged stirring pin. The method for disassembling the split friction stir welding tool of the present invention is simple to operate, can effectively complete the disassembly after the stirring pin breaks, has high disassembly efficiency, and reduces the production cost of the welding tool.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a method for disassembling a split friction stir welding tool. Background technique [0002] As a new solid-phase welding technology, friction stir welding is widely used in the manufacture of key and high-performance structural parts in the fields of aerospace, ships, automobiles and high-speed rail because of its obvious metallurgical advantages. During the friction stir welding process, due to the large force, the needle part of the stirring tool will eventually break and the welding will be terminated. At this time, a new stirring tool needs to be replaced, which obviously increases the production cost, especially for welding high melting point metals. [0003] CN101209512A proposes a combined friction stir welding tool, which is formed by assembling a shaft shoulder and a stirring pin, and proposes that the shaft shoulders and stirring pins of different structura...
