Our process know-how

We have state-of-the-art production and processing workshops. Together with our extensive know-how and long-standing, competent partners, we offer multifunctional system solutions of the highest quality in various industrial and technological fields. This also includes upstream and downstream processes such as welding, soldering or surface finishing.


Welding work is carried out by our certified partners. Thus we are able to offer the certification of level CL 1 and CL 2 according to DIN EN 15085 for the railway industry. In order to guarantee the process chain, SERTO is certified according to CL 1.

CL 1 Certificate

Orbital welding

Orbital welding is also part of SERTO's range of services. This work is carried out in-house on a modern system. Welding is carried out automatically with a supply of added inert gas with residual oxygen measurement. This allows tubes and entire assemblies to be welded in the highest quality.

Vacuum brazing

For the production of stainless steel products, our partners work with the vacuum soldering process, which results in great advantages over the conventional joining process in terms of quality.
