Abstract

The method concerns insert-cast welding of fine-pearlitic rails by pouring aluminothermally produced steel into a mould surrounding both rail ends. It is characterised by the following facts: (a) after the joint has cooled down, the running track and adjoining regions are shock-heated from the top by means of a welding torch for a period of 50 to 150 seconds; (b) the torch is supplied with oxygen at least at 10000 litres/hr and with propane or acetylene at 3500 litres/hr; and (c) the torch distance (a) measured in mm is equal to 0.1-1 times the numerical value of the wt. in kg/m of the rail.
