Friction Stir Welding (FSW): The effect of tilting angle
Friction Stir Welding (FSW) is solid-state process of combining two materials using frictional heat generated by rotating tool travel along the weld line. Development of FSW suffers implementation challenges due to expensive actual FSW machine available commercially. As alternative, a typical 3-axis...
