The fabrication of jet engine rotors by joining simple disk and ring shapes offers both weight and cost advantages; however, the metal joints must have excellent and completely reproducible mechanical properties. Inertia welding achieves this since it is a solid state joining process which forges the two parts together under an automatically controlled situation. The parameters for inertia welding jet engine nickel and titanium alloys are discussed. The cost and weight advantages occurring from elimination of mechanical joints and better material utilization are identified. Several typical applications are described.
