Introduction
Welding is a special process in the manufacture of railway vehicles and their parts. The required
provisions for this process are defined 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 inspe
