摘要： A friction welding apparatus includes a support, a headstock carrying a rotatable chuck for holding a first workpiece to be welded to a second static workpiece, the headstock being mounted on the support for movement axially of the chuck. Piston and cylinder type displacement means are connected between the headstock and the support for producing axial movement of the headstock and the chuck is provided with rotary drive means incorporating a shaft passing coaxially through the cylinder of the piston and cylinder device.
