Abstract
A method of fabricating a disk assembly for a turbofan engine is disclosed and includes the steps of forming a first and second disk and welding the second disk to the first disk to form a weld joint. A portion of the first disk and the second disk are removed along the weld joint on at least one surface to reduce a size of a heat affected zone and substantially reduce possible formation of material inconsistencies.
