Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] refer to figure 1 , figure 2 , image 3 and Figure 4 , a collet power supply assisted compound biaxial dynamic friction stir welding method, comprising the following steps:
[0022] 1) Clamping of workpieces to be welded: pass the first workpiece 1 to be welded and the second workpiece 2 to be welded through the negative dynamic clamping head 3, the positive dynamic clamping head 4, the first guide preload wheel 5 and the second guide preloader. The tightening wheel 6 is clamped and fixed on the welding workbench. The negative dynamic clamping head 3 and the positive dynamic clamping head 4 limit the first workpiece 1 to be welded and the second workpiece 2 to be welded between the first stirring head 7 and the second stirring head. 8 degrees of freedom in the axis A-A direction, the first guide pretension wheel 5 and the second guide pretension wheel 6 ...
