ROTOR PRODUCING METHOD Russian patent published in 2006 - IPC B23P15/04 B23K37/04 

FIELD: machine engineering, possibly manufacture of "blisk" type construction rotors.

SUBSTANCE: method comprises steps of joining blades with disc of impeller by welding and realizing their further working; before welding fixing blades and disc in attachment for assembling and welding at creating closed space between them; filling said space with metallic filler; successively welding all blades along annular periphery of disc while melting-through butt zones of blades and disc by depth of its whole cross section in lower position; removing metallic filler. Metallic loose material in the form of granules, powder, small grains or their mixture of materials corresponding to welded materials of blades and disc may be used as filler. Electron beam welding may be used for joining blades with disc.

EFFECT: enhanced efficiency, lowered labor and metal consumption, improved accuracy of rotor geometry size.
