This review paper discuss about the effect of tool geometry (Tool Pin Profile & Tool Shoulder Diameter) and
different friction stir welding parameters like Tool rotational speed, Tool travel speed, Tool force on butt weld joint of
different sizes and grades of material. The tool profile plays critical role in determining the end properties of welding joint
apart from other parameters like rotational speed, welding speed and axial force. [1] [2] The paper focuses on FSW
parameters in different conditions and their effect on mechanical properties and microstructure of weld joint. [2]The careful
selection of FSW process parameters can avoid the void formation, micro cracks and other defects.[15]
