Education, training, R&D

Our portfolio spreads from the practical training of welding, cutting, thermal spraying and mechanical joining over the qualification of skilled workers like welding supervision personnel (weling specialist, welding technician, welding engineer) to the further training of executive personnel. We are authorized to carry out standard courses according to guidelines of the German Association of Welding and Related Processes (Deutschen Verbandes für Schweißen und verwandte Verfahren e. V., DVS), the European Research Association Plate (Europäischen Forschungsvereinigung Blech, EFB), the European Federation for Welding, Joining and Cutting (EWF), the International Institute for Welding (IIW) and accoring to standards and guidelines on education and training. Our specifically designed seminars complete and enrich i.a. the know-how of the skilled and executive personnel on the following areas:

  • Gas welding (G)
  • Arc welding (E)
  • Metal aktive gas welding (MAG)
  • Metal Inert gas welding (MIG),
  • Wolfram Inert gas welding (WIG)
  • Plasma arc welding
  • plastic welding

For the education and training of skilled and executive personnel there are 150 welding spots, course rooms, practice laboratories and highly qualified, engaged teaching personnel with operational experience available.

Our division "education, training, R&D" promotes the applied development of joining procedures and the processing of materials and material combinations through research and development works, which happen on behalf of companies or on behalf of the public within national or international funding programmes. The resulting, practice oriented knowledge transfer benefits our courses.

Quality assurance

For the manufacturing of welded and corrosion protected components extensive quality requirements have to be met. Our team of the quality assurance deals with questions of welding, testing and surface technology and helps interested people with the accomplishment of the manifold tasks - from the planning, to the monitoring, inspection and manufacturing to the approval and the preparation of the relevant documentation. Certification of quality systems conducted with the DVS Zert e. V. in the sections DIN EN ISO 1090, DIN EN ISO 9001, DIN EN ISO 3834 and DIN EN 15085. As an acknowledged site according to DIN EN ISO 17660 we are authorized to issue manufacturers qualifications. As an independent site we can certify quality standards according to the guidelines of the Association Thermal Spraying (Gemeinschaft Thermisches Spritzen, GTS e.V.)
