Learn more about contactless electromagnetic weld pool backing

The WeldNova GmbH has many years of experience in the welding of thick sheets. We specialize in the use of non-contact electromagnetic weld pool backing for a wide variety of welding processes. Whether laser beam welding, arc welding or laser beam-arc hybrid welding; our flexible system can be used for all these applications. In particular, the number of layers can be reduced and material consumption lowered. We can also help you to integrate our technology into your existing system technology and bring your production chain up to the latest state of the art.

The field of application is not limited to thick sheets. The use of magnetic fields also brings considerable advantages for thin sheet applications, such as improving porosity, surface roughness or optimizing the upper bead geometry. We would be happy to assist you!

WeldNova combines many decades of experience in applied research and fundamental research in welding technology. The team passionately pours this know-how into innovative welding solutions. The core technology of WeldNova GmbH enables us to push the boundaries of what is possible in the welding industry.
Revolutionize the welding of thick-walled components with our innovative electromagnetic weld pool backing technology. Conventional welding processes such as submerged arc welding require extensive preparation and multiple welding layers, resulting in high costs and very long welding times. Our non-contact electromagnetic technology prevents droplet formation, enabling single-pass welding without the need for time-consuming edge preparation. This leads to significantly higher productivity, considerable cost savings and reduced CO2 emissions. The technology has a wide range of applications, from wind energy and shipbuilding to bridge building and vehicle construction. With the potential to transform industries, our magnet system can be easily integrated into existing and new welding systems.
