Friction Stir Welding (FSW) is a solid-state fabricating method used to produce superior quality welds with lesser defects. This process, generally performed at the melting temperature, utilizes non-consumable tool to develop frictional heat in the adjoining surfaces, and the base metal that is being joined does not melt. FSW is capable of fabricating Cu alloys, Ti alloys, Al alloys, Mg alloys, stainless steel and mild steel. In recent times, it was strongly utilized in welding of polymers. Further more, this process is used for fabrication of dissimilar materials, including Al to Mg alloys. The main benefits of FSW are: very low weld cost, superior tensile strength, low distortion, high microhardness, refined microstructure, produce defect free joint and environment-friendly. These reasons make the welding process highly suitable for distinct industrial applications (railway, shipbuilding, aerospace, Al industries, etc.). However, the weld quality and strength of FSW joints are also affected by tool pin profile. Hence, the paper reviews the FSW process, classifications, applications, process variables and the effect of distinct tool pin profiles on the mechanical properties of FSW Al alloys.


Welding is a joining process whereby two or more metals are joined with or without the use of heat or pressure, filler metal is added and solidified to become a superior joint. However, in brazing and soldering, the materials do not melt the base metal, but at low melting point, they are joined to bond them together. The welding process is generally split as gas welding, solid-state welding resistance welding, arc welding, intense energy beam welding, etc., and each process is further classified into several distinct processes. On the basis of whether the base metal is fused or not, the welding
