Institute of Materials Science and Welding


Passionate Lecturers and Researchers

Due to our high standards in teaching and research and the acquired external funds, we have managed to gradually create an exciting and stable working environment to ensure a maximum of freedom for each member of staff and student to acquire and deepen knowledge in the respective subject areas, all this in compliance with international standards.



Materials Science for a Modern Society

In the future, we will represent an international centre for developing, modelling and joining socially relevant, future-oriented, high-performance structural materials and feed the knowledge thus generated back into teaching and services.

Fields of work



  • Characterization of processing structures
  • Modelling and Simulation in Materials Science and Joining Technology
  • Improvement of performance characteristics of materials and processing technologies
  • Materials development
  • Materials selection
  • Process development


  • Consulting
  • Failure analysis
  • Preparation of expertises
  • Production and construction supervision
