About us
From welding research to your production line.
WeldNova is a team of welding engineers in Berlin and a spin-off of the Federal Institute for Materials Research and Testing (BAM). We take single-pass welding of thick sections from the laboratory into production.

The team
Our history
WeldNova is a spin-off of the Federal Institute for Materials Research and Testing (BAM) (opens in a new tab). Our technology comes from many years of basic research in BAM Division 9.3 Welding Technology under Prof. Dr.-Ing. Michael Rethmeier. In this work, the electromagnetic weld pool support developed into a practical tool for controlling the melt.
Ömer Üstündağ and Nasim Bakir, together with Dr. Gumenyuk, brought the technology to application readiness at BAM. Fatma Akyel adds experience from ISF at RWTH Aachen University, Christian Brunner-Schwer from the Fraunhofer Institute IPK.
We still work closely with BAM and other research institutes in Germany and combine that research background with hands-on experience from welding in industry.
Application center
- Fiber lasers up to 45 kW
- Welding cells with external linear and rotary axes
- Seam lengths up to 3 m, plate thickness adapted to your application
- Materials testing and metallography on request, and trials at your plant
