AA6061 aluminum alloy has a gathered wide acceptance in the fabrication of light weight structures requiring high strength to weight ratio and good corrosion resistance. Friction stir welding (FSW) is an emerging solid state joining process in which the material that is being weld does not melt and recast. This process uses a non consumable tool to generate frictional heat in the abutting surfaces. The present investigation is aimed to study the tensile strength, microstructures and corrosion
