Effect of the welding speed on the residual stress distribution in the AA7050 stationary shoulder friction stir welding

Abstract: Stationary-shoulder friction stir welding (SSFSW) is a relatively new solid-state joining technique which particularly attractive for alloys which are difficult to join via fusion welding. SSFSW creates a superior joint as compared to a standard fusion weld owed to the diminished levels of heat delivered to the workpiece. Due to the relative novelty of the process, the development of residual stress coupled with welding speed is relatively unknown, particularly in the normal and transverse direction of the weld.A key parameter related to the development of residual stress in this process is welding speed. It is proposed to measure 3 plates processed with different speeds and associated d0 specimens, with measurements placed across the width of the weld-affected zone. This will permit the correlation residual stress development with this parameter.
