Welding is generally regarded as a very specific process whose outcome cannot always be verified by testing after its completion. The quality of the weld cannot be ensured by testing the finished product, but it can be ensured by testing the welding process.

The reason for this is the never ceasing increase in requirements for the quality for both manufacturers and maintenance companies in the field of railway vehicles carrying out welding components, parts and sub-assemblies.

The required measures for this manufacturing process are set in the standard ISO 3834.

The standard EN 15085-2 establishes certification standards and requirements for manufacturers for the welding process and describes procedures for verifying the eligibility of producers.

The certificate is issued the basis of the screening requirements EN 15085-2. This certificate is necessary in order to qualify for the supply of components and parts for railway vehicles under the certification level CL1 – CL4.
