Abstract: AA6061 aluminium alloy (Al-Mg-Si) has widely accepted in the fabrication of light weight structures. Friction Stir Welding (FSW) process is an emerging solid-state joining process which offers several advantages over other fusion welding processes. The welding parameters such as tool rotational speed, welding speed, axial force and tool pin profile play a major role in deciding the joint strength. An attempt has been made to develop a mathematical model to predict tensile strength. Response surface method (RSM) has been used to develop the model and it is optimised using Hooke and Jeeves search technique to attain maximum tensile strength.
