Abstract

The invention discloses a same-direction different-speed double-shoulder stir friction welding device and an application method. An upper shaft shoulder and a lower shaft shoulder are respectively driven by different driving devices so that control means of rotation speed or axial pressure in a welding process can be increased, heat generated by friction of the upper shaft shoulder and the lower shaft shoulder with a workpiece can be changed due to different rotation speeds of the upper shaft shoulder and the lower shaft shoulder, the defect of coarse grains due to overheating of weld joint metal is avoided, welding quality and efficiency are improved, and the method is simple and reliable.

Description

technical field [0001] The invention relates to welding equipment for metal materials, in particular to a double-shoulder friction stir welding device with the same direction and different speed and its use method. Background technique [0002] There are two major types of currently known double-shaft shoulder friction stir welding devices: one is to use a stirring pin to connect the upper and lower shoulders, and the upper and lower shafts rotate synchronously, and the axial force has the advantage of "self-supporting", which is suitable for hollow type The welding of components produces a lot of heat during welding and has broad application prospects in the aerospace field; however, when the upper and lower shoulders rotate synchronously with respect to the workpiece during the coaxial double-shoulder friction stir welding process, the rotation speed of the upper and lower shoulders cannot be adjusted separately, which reduces heat production The control method is easy to ...
