FIELD: machine building.
SUBSTANCE: method can be used for production of diffusion welding of single-unit part for turbine machine, in particular, shaft, or disk, or single-unit vaned ring. Around mandrel (12) molding part is formed. Workpiece contains several coaxial and superimposed around mandrel layers of independent rings (10) from metal wires. Rings can be closed or open and pre-shaped. Between layers of wires can be layer of ceramic fibres coated with metal. Workpiece is subjected to hot isostatic pressing to obtain single-piece part. If necessary, produced part is subjected to machining.
EFFECT: method allows to produce article of round and non-round shape.
