| Abstract Scope |
Since the introduction of refill friction stir spot welding (RFSSW) in the early 2000s numerous evaluations of properties, performance and prototypes have been documented. RFSSW is a solid-state spot joining technique that is being evaluated as a rivet replacement technology for aerospace structures and fuselage fabrication. A production evaluation of overlapping wing skin assembly was completed with both bare metal and sealant at the skin interface. The production consisted of 105 spots per panel in a three-spot wide configuration on a 3” overlap. Weld properties were evaluated for spots produced on bare sheet as well as for sections with sealant applied. Furthermore, evaluations of the performance of repaired spots using the RFSSW process is demonstrated. Characterization of the weld interface, heat-affected zone, and complete through-thickness consolidation via computed tomography is presented. |
