THERMIT WELDING OF RAIL STEELS

British Railways R&D has investigated the welding of rails by the thermit process. This article discusses the importance of correct square-cut rail gaps, preheating and correct tapping to insure slag separation. Two processes are discussed--the short-preheat technique being particularly suitable for high-tensile steels.
