Abstract
A casting mold () consists of two mold halves (), which are intended for setting up on both sides of the welding groove () between two rail ends () to be connected, thereby forming a casting space () representing a cross-sectional profile of the rails. For sealing the casting space () between the rail bodies on both sides of the welding groove () and the wall portions () of the casting mold () that are facing this welding groove, inserted in gaps () are strips consisting of a compound at least containing expandable graphite, which as a result of heat being supplied during a preheating process expands and forms a reliable seal. In comparison with using filler sand at this point, there is the advantage that a much smaller quantity of compound has to be carried along when working on the laid track.
