Aluminium alloy has gathered wide acceptance in the fabrication of light weight structures requiring a high strength to weight ratio. Compared to the fusion welding processes that are routinely used for joining aluminium alloys, Friction Stir Welding (FSW) process is an emerging solid state joining process in which the material that is being welded does not melt and recast. Friction Stir Welding is the most remarkable welding technology that has been invented and developed in last two decades. This process uses a non-consumable tool to generate frictional heat in the abutting surfaces. The welding parameters such as tool shoulder diameter, tool rotational speed, welding speed, axial force play a major role in deciding the joint strength. In presen study an attempt has been made to develop a mathematical model to predict tensile strength of the friction stir welded AA8011 aluminium alloy by incorporating FSW process parameters. Four factors, five levels central composite design has been used to minimize number of experimental conditions.
