Abstract
A welding unit for welding rails of a track includes two unit bodies that can be moved in relation to each other by displacement cylinders along unit guides running parallel to the rails. The displacement cylinders are connected both to pull rods and to a crossbeam. Thus a simple design having high tensile forces is possible.
