A welding unit for welding rails of a track has a unit lower edge forming a lower boundary of the welding unit, with regard to a vertical, and a shearing device provided for removing a weld bead. A rail base section of the shearing device is designed to be lowered, relative to the welding unit, by way of a drive from a rest position situated above the unit lower edge into a shearing position situated below the unit lower edge. Thus, the welding operation can be carried out without lifting the rails from the sleepers.

Welding unit and method for welding rails of a track

A device for welding a rail joint of a track, comprising two rail clamping devices spaced from one another in a rail longitudinal direction which are connected to one another via push rods to press rail ends apart prior to welding. In this, it is provided that at least one rail clamping device is coupled to a transverse displacement device for flush-aligning the rail ends after being pressed apart.

Device for welding a rail joint of a track

A welding assembly () for welding two rails () of a track includes two rail clamping units () movable towards one another in an assembly longitudinal direction (). A power rail () provided for power transmission is configured as an assembly guide (), extending in an assembly longitudinal direction (), which is spaced from displacement drives () and connects both rail clamping units () to one another. The power rail () is equipped with a cooling device and displaceable in the assembly longitudinal direction () relative to the rail clamping unit () equipped with the power rail contacts ().

Welding assembly for welding two rails of a track

A welding apparatus for welding rails of a track comprises two welding units which are movable relative to one another and which are each equipped with clamping jaws at a lower end. The clamping jaws are configured for resting on a web of the rail. Each welding unit is connected to a supporting device which can move relative to the welding unit and which is provided for resting on the track during operation.

Welding apparatus for welding rails of a track

A welding unit for welding together two rails of a track includes two rail clamping assemblies which can be moved towards one another in a longitudinal direction of the rail along unit guides by compression cylinders. Each rail clamping assembly is equipped with clamping jaws which are displaceable in pairs in a pressing plane and each of which has a contact surface provided for application to a rail web. The clamping jaws are each constructed as clamping levers which are pivotable in the pressing plane about a lever pivot axis. The contact surface intended for application to the rail web is disposed at a first lever end spaced apart from the lever pivot axis. The two contact surfaces of each rail clamping assembly are each positioned closer to the oppositely disposed rail clamping assembly than the two lever pivot axes.
