Conference Name :
Friction Stir Welding is a novel material joining process which involves a tool probe which stirs the materials to be joined at the joining interfaces creating friction which in turn generates temperature resulting in material flow from one side to another due to which the joining of the materials takes place. The various parameters which influences the material joining process are the tool tilt angle, rotational speed, translational speed of the tool, tool geometry, axial force etc.. these process parameters influence the generation of heat and friction and influence the material flow pattern. In this present student the material flow due to change in the tool geometry is analysed using the principles of digital image analysis. This analysis is compared with mechanical and microstructural properties and results of the both the methods have shown good correlation.
