Research

We at SLV Halle take a holistic view in researching joining technology covering every aspect in creating new components from the design and welding process to materials, testing and data processing. We especially focus on pressure, beam and arc welding, and additive manufacture as joining methods. Our research involves developing specialised processes, process variants and welding technologies for new materials and composites and the challenges they involve, as further developments in materials and joining technologies require continuous adjustment in the design and arrangement of welding structures. A wide variety of methods for destructive and non-destructive testing as necessary for research and industry for characterising welded joins round off the range.

SLV Halle works together with industry and other institutes on basic and application research.

R&D cooperation

A variety of models and financing options are available for collaboration with companies, welding equipment suppliers and other R&D institutions:

  • Research and development projects for competitive purposes, such as within the AiF research association for welding and ancillary processes, allow partners from industry to participate in the project support committee with direct influence on project goals and results. 
  • Joint projects and marketing aims can be agreed with proportionate public funding from the German and Saxony-Anhalt government or the EU in national or international collaborative research.
  • Confidential joint agreements in contract R&D benefit clients with exclusive rights to the results. Various financing options are available for this type of agreement as well.

SLV Halle has around twenty employees, mostly engineers, technicians and welding experts working on technological development in specialised departments:

  • Beam welding
  • Arc welding
  • Pressure welding

Research and development for trades and industry
