Abstract: A method for welding components, which can be travelled upon, of a track by flash butt welding in a welding device, comprising the steps of straight flashing, preheating, flashing and upsetting, wherein the upsetting process generates a welding region, whereupon the welding region, from the welding heat, is subjected to a cooling step in which an austenitic structure of the welding region is converted into a pearlite structure, whereupon the welding region is subjected to a reheating step in which the welding region is heated to above the Ac1 conversion temperature, wherein the heating is performed by electrical resistance heating in the welding device using the power source that is used for the straight flashing, preheating and flashing, whereupon a region of the component, the region coming into contact with a wheel and being in particular a rail head, is subjected to cooling in the welding region.

Abstract: In a method for connecting switch or crossing parts made of austenitic manganese steel casting, or austenitic manganese steel rails, with rails of carbon steel, the parts to be connected, optionally upon interposition of an intermediate piece, are connected by friction welding, wherein the weld with the austenitic manganese steel is cooled at static air without heat treatment.
