Abstract: A friction welding method includes: applying axial force to first and second metallic components so as to force the components against each other at an interface therebetween, while oscillating the two components relative to each other in a cyclic motion, so as to generate friction and heat at the interface; rapidly stopping the cyclic motion; and applying a spike in the axial force to complete a weld between the first and second components.

Abstract: An in-jig assembly bond fixture for manufacturing a composite component having a plurality of parts includes at least one fixture for holding each of the plurality of parts in proper alignment relative to one another during a bonding operation. A mechanical mechanism is provided integral with the at least one fixture for applying a predetermined uniform compressive force to each bond line between each of the plurality of parts during the bonding operation. A plurality of heating elements is provided for applying heat directly to each bond joint and are each selectively located within the fixture for applying heat uniformly across each bond line during the bonding operation.
