Abstract
A workpiece holder for angularly reciprocatory friction welding apparatus includes clamp members for clamping the workpiece to a mounting table. The height and circumferential position of a drum is adjustable to facilitate blade attachment in manufacture of a blum. Means are also described for reinforcing the drum during blade attachment in order to absorb welding forces which might otherwise distort the drum surface.
