DEVICE FOR REINFORCING THE RAIL IN WELD JOINT REGION Russian patent published in 1998 - IPC

Abstract RU 2102501 C1

FIELD: devices for reinforcing the rails in weld joint regions. SUBSTANCE: device has body accommodating charge of sheet explosive and initiating unit. Shape of body and position of initiating unit are selected so that detonation wave in charge propagates square to rail longitudinal axis. Width of charge is equal to longitudinal size of low hardness zone. Side edges are bevelled. As a result of explosion reinforcement, hardness of running surface of weld distributes smoothly with no sections of low hardness in zones of thermal effect. Weld joints after obtained distribution of hardness is less liable to wear than nonreinforced ones. EFFECT: higher service characteristics and prolonged service life. 3 dwg
