A shift in maintenance: cost advantages of the Hedkote welding rail repair process

This paper examines the new opportunities and “a shift in maintenance (ASM)” from the development of the Hedkote process. Hedkote is a specialised method of repairing, rebuilding and recycling damaged, worn and old railway track and rail components in turnouts. Hedkote enables a repair which allows the original components life to be extended instead of a temporary repair until the rail can be replaced. Hedkote can be used to return damaged, worn or old components to close to their original condition and this process can be repeated several times before the rail requires replacement. The Hedkote process is a type of hardfacing that can be applied to the rail head using electric arc welding. Hedkote is a version of MIG welding process called Flux Cored Arc Welding (FCAW) and uses self shielded wires to remove the need for a shielding gas. Hedkote is suitable for all rail including standard, head hardened, austenitic manganese, chrome vanadium and titan rail and the repaired or rebuilt rail will significantly extend the life of the old rail whilst in some cases applying Hedkote can improve and extend the service life of a component. The Hedkote hardfacing layers also offer better protection against wear and impacts than the original rail. The Hedkote process has also been used as an alternative to explosive hardening of manganese components.
