Patent ID: 7775772

Claim:
A system for manufacturing an integrally bladed rotor, comprising: (a) a ring component, wherein the ring component further includes: (i) at least one metal matrix composite; (ii) a plurality of radially outwardly facing blade conical surfaces; and (iii) a build-up region, wherein the build-up region is located along the plurality of radially outwardly facing blade conical surfaces of the outer diameter of the ring component; (b) an airfoil component, wherein the airfoil component further includes: (i) a plurality of individual airfoil blades; (ii) wherein at least an internal core portion of each individual airfoil blade has been reinforced with at least one metal matrix composite; (iii) wherein each of the plurality of airfoil blades further includes a radially inwardly facing blade conical surface; and (c) inertia welding means for frictionally engaging under an axially applied weld load the ring component and airfoil component to effect an inertia weld therebetween along the build-up region of the ring component and the inwardly facing blade conical surface of the airfoil component.
