Apparatus for spin-welding comprises a spin welding machine having a spin welding head, a ram assembly, and a feed mechanism; the ram assembly is driven from a shaft and the feed mechanism comprises a rotating turret mounted on a shaft which is driven from the shaft via a Geneva mechanism. The spin welding head is driven by a low inertia DC servo motor operated by a programmable logic controller and timed from a switch unit driven off the shaft.
