Embodiment Construction
[0039] will be combined below Figure 1-5 An example of the present invention will be described. Such as figure 1 As shown, the friction stir welding apparatus 1 cools the upper tool 2 and the lower tool 3 by the air injected from the respective air nozzles 4, 5, and resists the friction caused by the rotating upper tool 2 and the workpiece 6 (parts to be joined 6a, 6b). The thermal expansion of each tool 2, 3 caused by heat is suppressed. Therefore, this friction stir welding device 1 is configured to properly maintain the gap G between the upper tool 2 and the lower tool 3 during friction stir welding, as image 3 As shown, forming the friction stir welded portion 7 having an appropriate thickness of the remaining mother plate thickness T between the overlapped workpieces 6 ensures the joint strength of the friction stir welded portion 7 . Furthermore, as shown in FIG. 2 , the friction stir welding device 1 is equipped with a non-contact temperature sensor 8 (tool tempera...
