Abstract: Friction stir welding (FSW) is a noteworthy technique this is used to fabricate the joints which are difficult to join by fusion welding methods and it gives fabulous results compare to Conventional Welding. In FSW process parameters such as Tool Rotation speed, Traverse speed, Axial Force, Plunge Depth and Tilt angle and tool geometry plays a vital role to obtain the defect free welds, towards this achievement the tool shape, especially the shoulder and pin structure design plays a crucial role. In this paper, equations are made using the MATLAB to find out the geometry of the shoulder and pin changes based on the thickness of the welding plate. This makes it possible to produce specific tool dimensions, by using these equations, a tool was developed. Similarly, the experiments were conducted by varying the plunge depth and correlated the results of microstructure, mechanical properties and fracture features
