ABSTRACT:
A process is described for inertia bonding a hollow shaft made of superalloy materials without causing compressive deformation in the shaft due to the high compressive forces generated in the segmented collet which grips the shaft. A method is also described for minimizing the residual stress in an inertia bonded joint, where the wall thicknesses of the two shaft portions to be bonded are unequal, by independently controlling the gripping forces on the portions so as to provide equal diameter reduction during the bonding process. A method for converting a front loading inertia bonding machine to a rear loading bonding machine is also described.
