Friction Stir Welding is solid state joining process of similar or dissimilar metals. This technique is more energy efficient, ecofriendly. Friction Stir Welding is one of the most significant developments in metal joining process. Most of studies in literature used threaded pins since most industrial applications currently use threaded pins. However, initially threaded tools may become unthreaded because of the tool wear when used for reinforced aluminum alloys or high melting point alloys. This paper gives information about different tool pins. Based on results that square pin tool is more efficient than other tools which we used because the square pin tool covers more volume compared to other tools.
