    Abstract: Cluster gear assemblies are produced by a method and apparatus which join a plurality of premachined gears by a common joining member. The plurality of gears are held in relative nonrotative relationship by special holding means which further establish precise angular and axial alignment between the gears and axial alignment between the joining member and the gears. Joining of the various members to produce the assembly is accomplished by friction welding.

    Abstract: DEFECTS AT THE CENTER OF INERTIAL FRICTION WELDED PARTS ARE PREVENTED FROM FORMING DURING THE WELDING PROCESS. THE FRICTIONAL HEATING IS INITIATED NEAR THE CENTER OF THE INTERFACE AT THE BEGINNING OF THE WELDING PROCESS. THE YIELDING OF THE PARTS IS CONFINED TO A NARROW BAND OF MATERIAL ON EITHER SIDE OF THE INTERFACE THROUGHOUT THE WELD PROCESS. THIS INSURES THAT THE CENTRAL PORTIONS OF THE END SURFACES OF THE PARTS BEING WELDED ARE MAINTAINED IN CONTACT THROUGHOUT THE WELD PROCESS AND ARE ADEQUATELY HEATED TO PRODUCE THE PLASTICITY REQUIRED TO FORM A WELD WITHOUT DEFECTS.

    Abstract: A process for inertia welding of steel to aluminum which may include the steps of cleaning and/or etching the parts, providing conical projections on the parts, providing a step load cycle wherein the final thrust load is high and close to the yield strength of the aluminum, utilizing moderately high speeds, the exercising close control of the alignment, amount of stickout, rigidity, and the triggering speed for the final load.
