Joining

New technologies for the joining of metallic and nonmetallic materials

 

Welding of hard-to-weld materials

The integration of laser beam welding with short-term heat treatment and adapted filler materials provides a new approach to crack free welding of tough materials such as hardenable and high strength steels, cast iron, aluminum and special alloys as well as parts of high stiffness.
 

Surface pre-treatment and constructive bonding

Our offered services include pretreatment processes, surface characterization, constructive adhesive bonding of various materials and the determination bonding strength and aging. A new direction aims at the integration of carbon nanotubes into the adhesives.
 

Special joining technologies

Expanding welding limits - new ideas to overcome challenges of modern materials and material combinations! The primary focus is on friction stir welding, laser beam soldering, laser induction roll plating, and electromagnetic pulse welding. The offer includes process development, prototype welding and systems development.
 

Component design

The designs we have developed for our partners are suitably strong and efficient to manufacture. With the help of finite element simulations for the design of structural components, we are especially able to take into account the specific changes to the materials due to the different processing steps.

Cooperation

Dresden represents a unique cluster of know-how in the field of joining and welding. The Fraunhofer IWS, the Institute of Manufacturing Technology of the TU Dresden and the University of Applied Sciences have been conducting research on this topic for many years. Besides thermal procedures like laser beam welding, electron beam welding and arc welding, joining processes such as friction stir welding, magnetic pulse welding, mechanical joining, adhesive bonding and hybrid technologies are of particular interest. This brochure provides an overview of available joining technologies and applications and offers service for component design, process monitoring, sensor technology and optical measuring techniques. Our goal is to further expand and to bundle the existing expertise in this field.
