Description: The friction stir welding (FSW) process is a revolutionary solid-state joining process that is finding broader acceptance as a manufacturing and assembly process for building of complex structures. While joining of Al alloys is now commonplace, there is considerable interest in extending the process to alloys with higher temperatures strengths such as Ti and Fe alloys. The FSW process typically provides improved mechanical properties relative to fusion welding with lower residual stresses and distortion. It is starting to provide breakthrough reductions in the manufacturing costs for both aerospace and non-aerospace systems. The implementation of this process into production applications has been rapid. Success stories in the aerospace industry include the successful implementation of friction stir welding in production on Delta launch vehicle and the Space Shuttle external tank. For aircraft applications, the near-term implementation of the process on the Eclipse 500, C-17 Globemaster and C-130 Hercules aircraft will lead to implementation of the process on large commercial aircraft. The friction stir welding sessions will provide a forum for both researchers and practitioners of the technology to present their recent findings and successes, and will enable them to interact with others in the FSW community.
