Abstracts: Friction-stir welding (FSW) is a solid-state joining process (the metal is not melted) that uses a third body tool to join two faying surfaces with the help of heat generation created by friction. FSW is newly invented and widely applicable in the fields like automobile, aero space and aeronautics where excellence and better quality of weld is desired. The present work is to study the effects of process parameters on weld quality in friction stir welding (FSW) process of silicon based Aluminum Alloy of grade AA6351 by studying the mechanical properties by performing tensile test on it. Tool materials and tool tilt angle were the two varying process parameters and spindle speed & traverse speed were the two constant process parameters kept in our research study. The proposed work will include the selection of those process parameters which are effective and upon which, restriction work has been done further fsw tools are been machined out of raw circular bar on centre lathe machine and hardened by applying heat treatment processes such as preheating and austenitizing followed by quenching in order to achieve the desired hardness
