METHOD OF WELDING OF RAIL BUT JOINTS OF SKIRT FISHPLATE-TYPE "РЭСФ-01" BY ALUMINOTHERMIC WELDING Russian patent published in 2014 - IPC B23K23/00 B60M5/00 E01B29/42 E01B11/52

Abstract RU 2530911 C2

FIELD: process engineering.

SUBSTANCE: proposed method can be used for welding of rail but joints of skirt fishplate-type "РЭСФ-01" designed to ensure their electric conductivity at railway length with electric track circuits provided with interlocking devices. At location of connector to be welded to rail, composite or all-welded metal holder is secured that comprises the base with yokes surrounding the rail head. Welding die is fitted in the holder to arranged collar skirt therein at the angle to rail side face. Solder is placed on the butt between connector and rail side face to rule out the leaks of thermic metal in butt clearance. Connector is welded by unitary thermic pencil to make molten pool between rain side face and skirt fishplate surface.

EFFECT: strong welds with high electric conductivity and antirust properties.
