Friction Stir Welding and Friction Stir Spot Welding

This book provides an overview and discussion of the current state of friction stir welding (FSW) and friction stir spot welding (FSSW) using interlayer materials to fabricate high-quality joints for specific applications, leading to the optimization of these techniques. It also discusses energy savings achieved by reducing the rotational speed of the FSW tool during material joining. Additionally, the book addresses the reduction of weld defects in the joint region and the improvement of joint efficiency.
