ABSTRACT:
A chain welding machine for the electrical resistance butt-welding of subntially C-shaped chain links is disclosed wherein two pair of electrodes are arranged symmetrically in relation to a median plane of the machine frame. Each pair of electrodes is supported on a pair of double-armed levers arranged for opposite rotation about a horizontal axis. Each electrode pair is adapted to grip, in plier-like fashion, one of the two ends of the chain link to be welded. Each lever pair is rotatably mounted to a trunnion which is, in turn, resiliently mounted in a bushing in the machine frame for absorbing any radial and/or axial loads imposed on the electrodes by misaligned or oversized chain links to be welded.
