LINEAR FRICTION WELDING METHOD

摘要

A method is provided of linear friction welding a rotor blade (12) to a disk (14). The method includes the steps of: providing a linear friction welding machine having disk tooling at which a disk (14) is mounted, and further having blade tooling (24) at which a blade (12) is mountable; mounting a dummy blade (26) at the blade tooling (24), the dummy blade (26) carrying one or more first measurement devices (28) which interact with the mounted disk (14) to measure the position of the dummy blade (26) relative to the disk (14); adjusting the position and orientation of the blade tooling (24) relative to the mounted disk (14) until the first measurement devices (28) indicate that the dummy blade (26) is in a suitable alignment with the disk (14) to start linear friction welding a blade to the disk; releasing the dummy blade (26) from the blade tooling (24) and mounting a production blade (12) thereat; and linear friction welding the production blade (12) to the disk (14) with the blade tooling (24) starting at the adjusted position and orientation.
