The influence of tool control in non-linear friction stir welding (FSW) on mechanical properties of joints was investigated. FSW is widely applied to linear joints. It is impossible for five axis FSW machines, however, to keep all the FSW parameters in optimum conditions at non-linear welding. Non-linear FSW joints should be made by compromise with the order of priority for FSW parameters. The tensile test results of butt joints with rectangular change in welding direction on plate plane (L-shaped butt joints) with various welding parameter change. It was found that turn to the retreating side is encouraged when welding direction change. And the method of zero inclination tool angle is effective at non-linear and plane welding.

In this study, experiments were performed to analyze the fracture surface and microstructural behavior of friction stir welded (FSW) AA5082-AA7075butt joints. Three samples at varying speeds and constant feed were prepared to identify optimum tool speed to produce FSW AA5082-AA7075 butt joints having maximum tensile strength and fatigue life. A scanning electron microscope (SEM) was used to analyze microstructure and fracture surfaces. The samples prepared exhibited a considerable difference in their fatigue life and tensile strength. Microstructural analysis showed the refinement of grains present in the stir zone (SZ), also known as the weld nugget, and thermo-mechanically affected zone (TMAZ). The study of the fracture surface showed that the mode of failure was ductile in nature
