Scope:

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.

Approach:

Comprehensive materials science expertise, close interdisciplinary cooperation with the IWS departments for high-speed laser processing, materials characterization and testing, and component design create the basis for technology and process developments for laser-based welding processes. Our services include:

  • Consulting
  • Feasibility studies
  • Implementation of R&D work
  • Technology developments + joint analysis
  • Process testing (applications + prototypes)
  • System developments in cooperation with our partners
  • Technical support for process introduction and training forengineers and system operators
  • Damage case analyses

Outcome:

Fraunhofer IWS is researching and developing material joints designed to last a lifetime. Aluminum, steel or even plastics are joined faster, more efficiently and with less impact on the material.
