摘要： A rotary friction welding process is provided. The process includes: providing a first axisymmetric workpiece (11) having a first annular weld surface (13), and a second axisymmetric workpiece (21) having a second annular weld surface (23), aligning the workpieces (11, 21) on a common axis with the weld surfaces facing each other, rotating one workpiece (11) about the axis relative to the other workpiece (21), and engaging the workpieces (11, 21) at the first and second weld surfaces (13, 23) such that the rotation raises the temperature at the weld surfaces (13, 23) to create a weld interface, and ceasing the rotation and allowing the weld interface to cool to weld the workpieces (11, 21) together at the interface. The first annular weld surface (13) is at a radially inward extent of the first workpiece (11), and the second annular weld surface (23) is at a radially outward extent of the second workpiece (21). On a longitudinal section through the aligned workpieces (11, 21), the first and second annular weld surfaces (13, 23) are inclined from the radial direction and are substantially parallel to each other such that the cooled weld interface is correspondingly inclined from the radial direction. On the longitudinal section through the aligned workpieces, each of the first and second annular weld surfaces (13, 3) is flanked by radially inner and outer side surfaces (14, 15 ; 24, 25) which are angled from their respective weld surface (13, 23), the first weld surface (13) and its side surfaces being shaped to thermally match the second weld surface (23) and its side surfaces (14, 15 ; 24, 25) across a line of initial contact of the first and second weld surfaces (13, 23) such the heat flows from the weld at all the side surfaces (14, 15 ; 24, 25) are substantially equal.

摘要： A method of friction welding comprising providing a first workpiece (24) having a first weld surface (38) and a second workpiece (26) having a second weld surface (40). In a first region (42) adjacent the first weld surface (38) the first workpiece (24) is arranged at an angle (±) of substantially 90° to the first weld surface (38) and in a second region (44) adjacent to the first region (42) the first workpiece (24) tapers away from the first weld surface (38). The first workpiece (24) is arranged such that in the second region (44) the first workpiece (24) is arranged at an angle (²) greater than 90° and less than 180° to the first weld surface (38). The first and second workpieces (24, 26) are arranged such that first weld surface (38) of the first workpiece (24) abuts the second weld surface (40) of the second workpiece (26). The first and second workpieces (24, 26) are moved relative to each other such that the temperature increases at the weld surfaces (38, 40) to create a weld interface (46) and then the movement is stopped to cool to weld the first and second workpieces (24, 26) together.

(b) positioning the first workpiece adjacent the second workpiece with the first faying surface being in engagement with the second faying surface;
(c) reciprocating the first workpiece and the second workpiece against one another such that the first faying surface moves relative to the second faying surface by a sweep length, such that a temperature at the first and second faying surfaces increases to create a weld interface;
(d) as the weld process progresses and each of the first workpiece and second workpiece are consumed into the weld interface, adjusting the sweep length such that the sweep length remains equal to a difference between the second faying length and the first faying length; and
(e) stopping the reciprocating and allowing the first workpiece and the second workpiece to cool to weld the first workpiece and the second workpiece together.
