A method for manufacturing an integrally bladed rotor includes fixturing a plurality of blade blanks having radially inwardly facing blade conical surfaces into a segmented blade ring assembly circumscribed around an axis. A rotor ring having a radially outwardly facing ring conical surface circumscribed around the axis is rotated to a contact speed. The rotor ring is fictionally engaged under an axially applied weld load with the blade ring assembly to effect a conical inertia weld along the mating blade conical surfaces and ring conical surface. The integrally bladed rotor includes a plurality of airfoils circumferentially distributed about and integral with a rim. The airfoils extend radially outwardly from respective airfoil bases on a radially outer flowpath surface of the rim to airfoil tips. A conical inertia weld is located between the airfoil tips and a radially inwardly facing rim surface of the rim.
