ABSTRACT:
A device exists for translational friction welding of a first component and a second component. The device includes a holder to hold the first component within an open ended frame having an open space within for receiving the first component. The frame includes a base and transversely spaced apart first and second members which longitudinally extend from the base to an open end of the frame at which is located a clamping feature used to clamp the first component in the holder with a clamping force having force components oriented along three orthogonal axis and has opposing tapering pressure surfaces which open outwardly in a first direction and taper inwardly in a second direction which is perpendicular to the first direction. A sacrificial block on the second component has block ends with surfaces that conforms to the surfaces of one of the clamping features. In a preferred embodiment the clamping feature is a compound wedge shaped notch and the block ends have corresponding compound wedge shapes.
