This document specifies restoration by electric arc welding and is limited to the head of the rails only.
This document describes the approval systems for consumables and procedures used in manual metal arc and flux cored metal deposit rail repair welding. This document includes the quality-related tasks and responsibilities of personnel involved in the electric arc repair welding of rails. This document applies to plain rail and switches and crossings manufactured from new Vignole railway rails R200, R220, R260, R260Mn, and R350HT grades rails of 27 kg/m and above as contained in EN 13674-1, EN 13674-2 and EN 13674-4.
The permitted welding processes are limited to Electric Arc (EA) in accordance with EN ISO 4063 and are by description Process No 111: SMAW (Shielded Metal Arc Welding) and Process No 114: FCAW (Flux Cored Arc Welding).
This document can 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 document, except when located within 500 mm of manganese crossings. Where repairs are required within 500 mm, refer to EN 16725.
Bahnanwendungen - Infrastruktur - Aufarbeitung von Schienen durch elektrisches Lichtbogenschweißen
Dieses Dokument behandelt elektrische Reparaturschweißungen, die sich nur auf den Schienenkopfbereich beziehen.
Dieses Dokument beschreibt ein Zulassungssystem für Schweißzusatzwerkstoffe und Verfahren bei der Ausführung von Reparaturschweißungen an Schienen mit Metall-Lichtbogenhandschweißung und Schmelz-Fülldrahtschweißungen. Dieses Dokument schließt die qualitätsbezogenen Aufgaben und Verantwortlichkeiten des Personals, das sich mit der elektrischen Lichtbogenreparaturschweißung an Schienen befasst, ein. Dieses Dokument ist anzuwenden für Bauteile des Hauptgleises und der Weichen und Kreuzungen für Stahlsorten R200, R220, R260, R260Mn und R350HT mit einer längenbezogenen Masse ab 27 kg/m in Übereinstimmung mit EN 13674-1, EN 13674-2 und EN 13674-4.
Die zugelassenen Schweißverfahren und ihre Anwendungen sind begrenzt auf das elektrische Lichtbogenschweißen (EA) in Übereinstimmung mit EN ISO 4063 und der dort beschriebenen Verfahrens Nr. 111: SMAW (Metall-Schutzgasschweißen, en: shielded metal arc welding) und der Verfahrens Nr. 114: FCAW (Metall-Lichtbogenschweißen mit Fülldrahtelektrode ohne Schutzgas, en: flux cored arc welding).
Dieses Dokument kann an Baustellen im Gleis oder außerhalb des Gleises angewendet werden. Die abbrennstumpfgeschweißten Schienenenden von Kreuzungen aus austenitischem Manganstahl werden in diesem Dokument berücksichtigt, es sei denn, sie befinden sich innerhalb von 500 mm von Mangan-Herzstücken. Wenn Reparaturen innerhalb von 500 mm erforderlich sind, wird auf EN 16725 verwiesen.
Applications ferroviaires - Infrastructure - Réparation des rails par soudage à l’arc électrique
Le présent document spécifie les exigences de la réparation de rails par soudage à l’arc électrique strictement limitée au champignon du rail.
Le présent document décrit les procédures d’approbation relatives aux consommables et aux modes opératoires, que la réparation des rails soit réalisée au moyen d’une électrode enrobée ou d’un fil fourré. Le présent document définit également les missions et responsabilités du personnel impliqué dans la qualité des réparations de rail par soudage à l’arc électrique. La norme s’applique aux rails de voie courante, aiguillages et coeurs d’appareils de voie fabriqués à partir de rails Vignole neufs de masse supérieure ou égale à 27 kg/m conformément à l’EN 13674-1, l’EN 13674-2 et l’EN 13674-4, et de nuances d’acier R200, R220, R260, R260Mn et R350HT.
Les procédés de soudage autorisés sont limités aux procédés de soudage à l’arc électrique conformément à l’EN ISO 4063 et décrits par le Procédé n° 111 : soudage à l’électrode enrobée et par le Procédé n° 114 : soudage au fil fourré.
Le présent document peut être applicable in situ, en ou hors voie. Les antennes soudées par étincelage aux coeurs d’appareils de voie en acier austénitique au manganèse sont incluses dans le présent document, à l’exception des zones situées à moins de 500 mm de l’acier au manganèse. Si des réparations sont nécessaires dans un rayon de 500 mm, se référer à l’EN16725.

European foreword
This document (prEN 15594:2025) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15594:2009.
— normative references have been updated;
— additional rail steel grades have been included;
— microstructure and macrostructure requirements have been updated;
— an Annex ZA has been included.
The purpose of this document is to unify the restoration of rail electric arc welding across Europe. The
document provides control systems for the approval and qualification of welding processes, welding
procedures, welding consumables, contractors and welders for the successful delivery of welds into track.
This document has been prepared under a standardization request addressed to CEN by the European
Commission. The Standing Committee of the EFTA States subsequently approves these requests for its
Member States.
For the relationship with EU Legislation, see informative Annex ZA, which is an integral part of this
document.
