Laser Welding

As a modern joining process, laser beam welding offers a wide range of industrial applications and, compared to conventional processes, is often the safest as well as most resource- and cost-efficient solution for producing metallic joints. With our ear to the ground, we combine the advantages of laser beam welding with the technological trends of today and tomorrow: hydrogen-powered mobility solutions, artificial intelligence, climate-friendly aerospace, smart medical technology and much more.

Customized laser processes, system solutions and component concepts

As a globally renowned research institute, we are always striving to find the objectively best solution for your individual requirements. We combine materials science know-how with state-of-the-art systems engineering to develop customized laser processes and system solutions as well as sustainable component concepts for you – even across current technology and process limits.


Range of services

Regardless of the maturity and development level of your project, we support you with consulting services and feasibility analyses, application-oriented research and development work, and series-production implementation.
