Research and Development (R&D) of Friction Stir Welding (FSW) has expanded rapidly since the inception of the technology in 1991. As the technology has matured in recent years, FSW has been of increasing interest to not only those focused on R&D but also to the manufacturing community. The technology is being readily applied to aluminum production components and developed for titanium and super alloy applications. FSW is now being investigated for a wide range of aerospace applications in both the engine and airframe industry for reasons of cost and performance. Recent advancements in the FSW for joining of aluminum, titanium, and nickel based alloys will be discussed.
