description This invention relates generally to gas turbine engines, and more specifically to rotor shafts used with gas turbine engines. A method for manufacturing a rotor shaft includes fabricating a first shaft portion that extends axially from a first end to a second end, fabricating a second shaft portion that extends axially from a first end to a second end, and coupling the second shaft portion to the first shaft portion with an explosive bonded joint such that the second shaft portion is aligned substantially concentrically with respect to the first shaft portion, and such that the bonded joint extends obliquely with respect to a centerline axis of symmetry of the rotor shaft.
