  • Patent number: 12281448
    Abstract: A welding unit for welding rails of a track includes a first sub-unit which is displaceable on unit guides in a rail longitudinal direction relative to a second sub-unit by using displacement cylinders. Each sub-unit includes clamping cylinders disposed underneath the unit guides and coupled to clamping jaws for clamping the rails. The two sub-units are connected by the displacement cylinders in that a cylinder body of the respective displacement cylinder is connected to one sub-unit and a piston rod of the respective displacement cylinder is connected to the other sub-unit. Thus, it is not necessary to support the displacement cylinders relative to a transverse beam disposed at the front.
