FIELD: engines and pumps.
SUBSTANCE: in making vaned disc with multiple vanes jointed said disc radially, vane with ledge to joint it to said disc is formed and said ledge is jointed to disc kedge by linear friction welding. Prior to linear friction welding, said vane is clamped in tooling, brought in contact with said disc and loaded with axial welding force. Then without reducing applied welding force, the vane is fixed in tooling by full clamping force to make linear friction welding by friction of vane and disc. Vane fixture is retained during the entire welding process.
EFFECT: higher quality of welding.
