ABSTRACT:
A method for manufacturing bladed disks, or blisks, for turbines by press welding of blades or outer airfoil elements to blade stives or inner airfoil elements on a disk is characterized by the provision on the outer and inner airfoil elements of flanges of excess flash material having alignment holes for dowel pins that assure alignment of leading and trailing edges of the airfoil elements during pressure welding, followed by removal of the excess flash material and the included dowel pins.
