Abstract

See full text

In a method for connection of railway point components (1) such as, for example, frogs consisting of austenitic cast hard manganese steel, or manganese steel rails, to rails (2) made from carbon steel, with the utilization of an intermediate piece (3) made from low-carbon austenitic steel, in which method the intermediate piece (3) is first-of-all welded to the standard rail or connecting rail (2), following which, after cutting off the intermediate piece (3) to a length of less than 25 millimeters, in a second welding operation, the intermediate piece (3) is welded to the component (1) consisting of cast hard manganese steel or to the manganese steel rail (1), an intermediate piece (3) consisting of a low-carbon, austenitic, steel, in particular a chromium-nickel-steel, stabilized with niobium and/or titanium, is utilized and, following the first welding operation, a heat treatment, in particular a diffusion-solution at a temperature between 350.degree. C. and 1000.degree. C., is carried out.
