A stationary shoulder friction stir welding (SSFSW) technique was developed for the joining of high temperature, low conductivity materials, and experimental results were obtained for butt and lap welds in Ti-6%Al-4%V alloys produced using 1D and 2D welding paths. SSFSW prototypes were realised based on the concept of a rotating pin located in a non-rotating shoulder component. SSFSW was used for rapid prototyping of titanium alloy parts and sample flange structures were produced by multirun lap welding. Improved structural design, cooling systems and flexible tool holding are discussed for second generation SSFSW equipment.
