METHOD FOR MANUFACTURING OR REPAIR OF MONOBLOCK BLADE DISK AND DISK FOR MONOBLOCK BLADE DISK Russian patent published in 2009 - IPC F01D5/34 B23K20/12 

FIELD: engines and pumps.

SUBSTANCE: method for manufacturing or repair of monoblock blade disk includes stage of welded seam surface formation on protruding platform, being part of disk. Surface of welded seam is intended for provision of the following stage for connection of blade on protruding platform of disk by linear friction welding. Stage of welded seam surface formation is realised so that it contains at least two flat adjacent sections installed serially along protruding platform. Another invention of group is related to disk for making of monoblock blade disk. Disk for making monoblock blade disk comprises at least one protruding platform, on which welded seam surface is arranged, which is intended for provision of blade joint on protruding platform of disk by linear friction welding. On protruding platform surface of welded seam comprises at least two adjacent flat sections, which are installed radially along protruding platform.

EFFECT: arranging surface of welded seam as maximum close to disk surface, and also reducing costs in manufacturing or repair of monoblock blade disk.
