Bibliography

This European Standard specifies restoration by electric arc welding and is limited to the head of the rails only.This European Standard describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. The standard includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. The standard applies to plain rail and switches and crossings manufactured from new vignole railway rails R200, R220, R260, R260Mn and R350HT grade rails of 46 kg/m and above as contained in EN 13674-1.The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4063 and are by description Process No 111: MMA (Manual Metal Arc) and Process No 114: FCAW (Flux Cored Arc Welding). Their applications are described.This European Standard may be applied in situ, at line side or at out of track locations. The flash welded leg ends of austenitic manganese steel crossings are included in this standard, except when located within 500 mm of manganese crossings.
