CA 2593984
The invention relates to a method for joining points parts or intersecting parts made of hard cast manganese steel or hard manganese steel rails to rails made of carbon steel, wherein the parts that are to be joined are optionally joined by friction welding with an intermediate part placed therebetween. The weld joint to the hard manganese steel is cooled with stationary air without any heat treatment.
L'invention concerne un procédé pour assembler des pièces d'aiguillage ou de croisement moulées en acier austénitique au manganèse ou des rails en acier austénitique au manganèse avec des rails en acier au carbone. Selon ce procédé, on soude par friction les pièces à assembler, éventuellement en intercalant une pièce intermédiaire, la soudure avec l'acier austénitque au manganèse étant refroidie à l'air statique sans traitement thermique.
