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

摘要： A method of friction welding a first workpiece to a second workpiece, includes the first workpiece with a first faying surface having a first faying length, the second workpiece with a second faying surface having a second faying length, the second faying length greater than the first faying length; positioning the first workpiece adjacent the second workpiece; reciprocating the first workpiece and the second workpiece against one another, the first faying moves relative to the second faying by a sweep length, a temperature at the first and second faying surfaces increases to create a weld interface; each of the first and second workpieces are consumed into the weld interface, adjusting the sweep length the sweep length remains equal to a difference between the second and the first faying lengths; and stopping the reciprocating and allowing the first and second workpieces to cool to weld the first and second workpieces together.

摘要： A method of joining a first component to a second component at respective connection surfaces, comprising, in order, applying a local surface treatment to the connection surface of at least one of the first and second components in order to locally alter the microstructure to a depth of between 60 μm and 10 mm below the connection surface; and joining the first component to the second component using a welding process.

摘要： A method for welding together pieces which form a curved or angled end product using a friction welding process. The method includes: providing first and second pieces which together define the end product geometry, each piece including an end product geometry portion and a sacrificial weld portion, the sacrificial weld portion forming a dog-leg relative to the end product geometry portion and terminating in a planar weld interface surface. The pieces are arranged with their planar weld interface surfaces together at a weld surface interface and the sacrificial weld portions in coaxial alignment. Mechanical friction is applied between the planar weld interface surfaces sufficient to plastically deform the sacrificial weld portions. An axial force is applied along the co-axis of the sacrificial weld portions sufficient to upset the sacrificial weld portions and bring together the end product geometry portions. The sacrificial geometry portions are removed to provide the end product.

摘要： A friction welding process includes: providing a first workpiece having a first weld surface, and a second workpiece having a second weld surface; aligning the workpieces with the weld surfaces facing each other, moving one workpiece relative to the other workpiece, and engaging the first and second weld surfaces such that the movement raises the temperature at the weld surfaces to create a weld interface; and ceasing the movement and allowing the weld interface to cool to weld the workpieces together at the interface. The first workpiece has a plurality of flash removal channels formed in and/or adjacent to the first weld surface. The channels provide pathways for ejection of material from the weld interface during welding.
