Introduction

Welding is a special process in the manufacture of railway vehicles and their parts. The required

provisions for this process are laid down in the standards series EN ISO 3834. The basis of these

provisions is the basic technical welding standards in respect of the special requirements for the

construction of railway vehicles.

This document aims to define the terms of enforcement applicable to European standards. It should not

be construed as a substitute to these standards.

This document can also be used by internal and external parties, including accredited certification bodies,

to assess the organization's ability to meet customer, regulatory, and the organization's own

requirements.

4 Quality requirements for welding during maintenance
4.1 General

For maintenance welding of railway vehicles and their components, the standard EN 15085-4 shall be

applied.

For maintenance welding all necessary information about the vehicle such as documentation of vehicle

manufacturer (drawings, operation manuals, manufacturer requirements) as well as special guidelines

and working instructions should be available.

If damage occurs repeatedly on similar components or if a maintenance welding activity introduces a

change with respect to the original drawing, all involved parties shall be informed.

4.2 Welding coordination

In addition to the classification level defined in EN 15085-2:2007, 5.3, given the specific nature of

maintenance welding, the responsible welding coordinator shall have experience in maintenance.

Experience shall be consistent with the classification level and typical activities carried out by the

manufacturer and shall be proven by documentary evidence according to EN 15085-2:2007, Annex D.

4.3 Conditions for welding
4.3.1 General

All welding should be carried out within a suitable workshop. However, welding outside a workshop or

welding temporary repair may be carried out if the additional provisions given in 4.3.2 and 4.3.3 are

respected.
4.3.2 Welding outside a workshop

Welding outside a welding workshop shall only be carried out if the following conditions are fulfilled:

— Welding shall be performed in accordance with EN 15085 all parts.

— Welding shall be performed in accordance with the recommendations of the EN 1011 series. The

environmental conditions (e.g. wind, rain, relative humidity, temperature, accessibility etc.) shall be

taken into account to ensure the quality of the welding operation.

— The documentation shall include any special conditions that have to be met to put the vehicle back

in service.

If conditions above cannot be accomplished, welding outside a workshop shall be considered as a

temporary repair, see 4.3.3.
4.3.3 Welding temporary repair

Welding temporary repairs are carried out only to ensure safe movement of a railway vehicle to the

nearest appropriate workshop. They shall not be considered as a maintenance activity as defined in the

scope of this standard.

A description of the welding activities undertaken during temporary repair shall be documented,

including the location of any additional welds, in order to support any special conditions that shall be met

to move the vehicle.
