Abstract

A model is presented for the linear friction welding process used for blisk manufacture in modern aeroengines. Both the conditioning and equilibrium phases are accounted for. The heating is accomplished by applying an interfacial friction condition. The separate workpieces are assumed to be joined after reaching a critical, predefined temperature. The subsequent equilibrium phase is modelled as a single workpiece, with the usual rippled flash formation occurring. The predictions of the model are compared critically against the results of targeted experimentation, e.g. upsets rates and temperature cycles.
