Recent Trends in Friction Stir Welding

Abstract

Welding technology has brought a milestone change in metal joining processes and its applications and almost eradicated some other metal joining processes (riveting etc.). Friction stir welding is a solid state welding technique comparatively recent than others. This study intends to elucidate the current scenario in the field of friction stir welding with special focus on dissimilar metal friction stir welding, underwater friction stir welding and hybrid friction stir welding. Further, future challenges in the friction stir welding have been described.
