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 with respect to the special requirements for the
construction of railway vehicles.This series of standards applies to welding of metallic materials in the manufacture and maintenance of
railway vehicles and their parts.It describes the control for the welding process for railway vehicles and their components for new
manufacture and maintenance.With respect to the railway environment, this series of standards defines the quality requirements for the
welding manufacturer to undertake new building and repair work.Components, parts and subassemblies are assigned a classification level, based on their safety relevance.
According to these levels, qualifications for welding personnel of the manufacturer are specified.
This series provides an essential link between the weld performance class defined during design, the
quality of the weld, and the demonstration of the required quality by inspection.
This series of standards does not deal with product qualification.NOTE This series standard can also be used by internal and external parties, including 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 welding4.3.1 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.4.4 Restr
