Method and apparatus for bonding crossing rails

摘要

A method for bonding a crossing rail includes the steps of: inserting an insert member (5) having a melting point Ti that is lower than a melting point Tb of a metal material of a crossing rail (1) made of a high manganese cast steel and a regular rail (3), in between the crossing rail (1) and the regular rail (3), and while applying a pressure to a bonding interface of the crossing rail (1) and the regular rail (3) through the insert member (5), heating the bonding portion to a temperature T to meet a relationship, Ti
