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 are the basic technical welding standards in respect of the special requirements for the
construction of railway vehicles.
This document is aimed at defining the terms of enforcement applicable to European Standards. It is not
construed as a substitute to these standards.
This document 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 Inspection and testing of welded joints
4.1 General
The manufacturer is responsible for the correct implementation of inspection activities according to the
requirements of this standard. For maintenance prEN 15085-6:2020 shall also be applied.
The supervision of inspection and testing is in the tasks of the responsible welding coordinator and the
welding coordination team, as referred to in Annex A of FprEN 15085-2:2020.
This supervision shall be conducted in a continuous way. It should be documented in specific steps, for
example during the execution of periodic internal audits in the welding workshop.
4.2 Inspection and testing before welding
Before beginning any type of welding activity, the welder or welding operator shall check the following
items:
— the welding machine is checked and in working order;
— the general conditions of the working area fulfil the requirements (see also prEN 15085-4:2020,
Clause 5), e.g. temperature of the environment, correct conditions of the used jigs and fixtures;
— availability of the work instructions and necessary design documents;
— conditions of the weld preparation and the correct tack welds of the parts to be welded (conditions
of cleanliness and assembly of the pieces in accordance with the design and/or the WPS);
— identification of the parts to be welded;
— the necessary production weld tests according to prEN 15085-4:2020, 4.2 are done before the start
of the daily production, if required (e.g. resistance welding) under the real conditions;
— compliance of the welding consumables with the WPS.
In case of deviation the information shall be transmitted to the responsible person.
4.3 Inspection and testing during welding
The welders or welding operators performing the job shall check and ensure the following:
— adequate cleaning and shape of the joints during the intermediate passes;
— compliance with the prescribed values of the pre-heating and/or interpass temperatures;
— compliance with the WPS and/or work instructions;
6

---------------------- Page: 8 ----------------------
oSIST prEN 15085-5:2020
prEN 15085-5:2020 (E)
— compliance with the sequence of operations if prescribed in specific operating instructions (e.g. the
welding sequence plan).
The process steps and phases in which it is necessary for the welding activity to be supervised by the
responsible welding coordinator or his deputy shall be explained by welding planning documents (see
prEN 15085-4:2020, 4.1).
If the welding sequence plan or test plan requires the check of a weld during production, welding shall
be continued only after the weld has been checked.
4.4 Inspection and testing after welding
4.4.1 General
Inspection and testing after welding shall be undertaken by competent personnel. For CT 1 and CT 2 the
personnel shall be independent of welding production.
4.4.2 Checks by the welder or welding operator
After welding, the welder or welding operator shall carry out the following checks:
— that the weld is complete;
— that the weld is cleaned;
— that the profile and dimensions of the weld conform to the drawing.
4.4.3 Requirements for visual examination personnel
The following people are considered capable to carry out visual examination on welded joints:
— personnel qualified according to EN ISO 9712 (at the appropriate level according to relevant
assigned tasks)
— recognized welding coordinator, only for direct-unaided technique (as defined in EN ISO 9712)
— qualified welding inspector (e.g. E/IWI-C/S), only for direct-unaided technique (as defined in
EN ISO 9712)
Confirmation of visual acuity is required.
The following personnel is also considered capable to carry out visual examination on welded joints
having inspection class CT 3 and CT 4:
— personnel already qualified according to EN ISO 9712 for other non-destructive testing (PT, MT, UT,
RT, ET) when supported by specific training for visual examination in accordance with EN ISO 17637;
— personnel trained in accordance with EN ISO 17637, providing that the following conditions are met:
— in CT 4, a declaration by manufacturer about training activity shall be available;
— in CT 3, evidences and documents are required (technical contents and duration of training,
system and criteria used for final assessment of knowledge, issuing of an “authorization to
operate” document for each individual with relevant duration).
Confirmation of visual acuity is required.

4.4.4 Requirement for other non-destructive examination personnel
All NDT (RT, UT, MT, PT or ET) shall be performed by personnel qualified by examination according to
EN ISO 9712, (at the appropriate level according to relevant assigned tasks). Requalification is necessary
after five years.
4.4.5 Type and extent of non-destructive testing
Table 1 defines the type and extent of the testing to be carried out during production. This is based on
the relationship between the weld performance class of the welded joint assigned by the design engineer
and the resulting inspection class (see prEN 15085-3:2020).
The tests described in Table 1 shall be carried out on products manufactured during production in
accordance with the frequencies indicated therein and as per the weld performance class specified in the
engineering documentation (e.g. on the drawing) by the design department.
The test methods indicated in Table 1 shall be the minimum capable of ensuring compliance of the welded
joints. Additional tests depending on materials, design, customer requirements, specific request of the
welding coordinator, may be necessary.
In the case of detecting not acceptable imperfections during the tests indicated in Table 1, the procedure
for management of non-conformity shall be applied, with the extension of the testing
