    摘要: A method of joining frogs consisting of wear-resisting austenitic manganese steel casting to rails of carbon steel by welding and with the aid of an interposed connector consisting of austenitic low-carbon steel, characterized in that the connector is first welded to the regular rail or interconnecting rail, particularly by flash-butt welding, that the length of the connector which has been welded to the regular rail is limited to 20 to 25 mm, at most, preferably to 15 to 20 mm, that in a second welding operation the frog consisting of a wear-resisting manganese steel casting is welded to the connector, preferably by flash-butt welding, and that the cooling after the second welding operation is effected at a higher rate than the cooling after the first welding operation.
