ABSTRACT:
A method for repairing or manufacturing an article, such as a bladed disk, having an integral projection, for example an airfoil, includes first removing a damaged projection to provide a stub, or in new manufacture providing the stub. A collar shaped to register with the stub is provided and bonded to the stub to generate a stub-collar combination. Then a replacement or new projection member is bonded to the stub-collar combination. Finishing then provides the article. Apparatus includes the combination of a metal attachment die and a heating means retained in a recess of the die during bonding.
