Process Developement of Integral Fasteners Using Friction Stir Spot Welding With “C-Frame” end Effector on an Aircraft Cabin Door Made From AA6061-T6 and AA2024-T3

摘要: Application of Friction Stir Spot welding (FSSW) to the creation integral fasteners on an Aircraft Cabin Door using industrial robot with a “C-Frame” end effector is explored. Plunge depth control, sheet lifting, pin temperature and anvil sticking issues are addressed. Tools various shoulder concavities investigated. Through optimization forge load, spindle speed process duration (dwell) time, fastener shear loads found be 1.8 times higher than resistance spot welding. Optimized cooling time up 9 seconds effector. Preliminary Welding Procedure Specification (pWPS) per AWSD 17.3 developed. Frame skin assembly articles fastened together three unique joining sequences. A “go — no go” inspection gage used verify pWPS standards. Hard tooling shorten cells multiple studies proposed for further study.
