FIELD: process engineering.
SUBSTANCE: invention may be used in fabricating integral vaned disk for, for example, gas turbine rotor. Vanes 1 are arranged to make a rim in mould that features rotational symmetry. Disintegrating or decomposing material preheated to temperature exceeding its fusion temperature is poured on said rim. Moulded rim 10 is withdrawn from said mould after curing of said material. Friction welding is used to joint moulded rim 10 to disk 4 Disintegrating or decomposing material is removed.
EFFECT: simultaneous jointing of multiple vanes to disk by friction welding.
