Abstract:
Metal airframe structure for commercial aviation has traditionally been constructed from riveted and bolted built-up assemblies. This approach has led to complex assemblages joined together by numerous fasteners. Friction Stir Welding (FSW) holds promise for reducing this complexity within certain areas. 747F cargo nose barrier beams were s elected as the first application of a special lean technology transfer program undertaken 1) to demonstrate and document the potential benefit of FWS and 2) to optimize the efficiency of the 7075-T6 plate- to-extrusion joints of the beams. Mechanical test results from this program showed that a stable and reliable process, as evidenced by a consis tent level of tensile properties, is provided by FSW.
