Abstract
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.
