FIELD: manufacture of component of stator or rotor such as disc or ring with large number of blades.
SUBSTANCE: at least one blade is joined with annular member. At least part of inner surface of annular member is inclined relative to central axis or outer surface of said member is inclined relative to central axis. Disc or ring with blades has surfaces corresponding to shape of inclined surface of annular member. Said annular member and disc or ring with blades are moved one relative to other in axial direction till abutting their inclined surfaces and at least one blade of disc or ring is joined with annular member by means of bonding material. At heating blade, annular member and bonding material butt joint is formed. Then bonding material is heated till its melting temperature. After solidification blade is reliably joined with annular member.
EFFECT: enhanced efficiency, lowered expenses for making high-strength component of stator or rotor.
