Centre for Joining and Structures (CJS) is a platform for collaborative research within the area of joining technology. Research is conducted in close collaboration with the industry and Swedish Welding Commission, with the aim of delivering outcomes of immediate usefulness and relevance. 

CJS gathers companies from different sectors, for example, the automotive industry, material suppliers, heavy machinery, manufacturers of welding equipment and consumer products. Together we make sure challenges are being solved in an efficient way.

 Our research is commonly related to the following areas:

  • Decreased emissions and improved load capacity
    – Lighter materials
    – High strength materials
    – New material combinations (multi-material construction)
    – Environmental impact
  • Improved lifespan
    – Fatigue properties/weld geometry
    – Increased lifespan for existing structures
    – Corrosion resistance/joint design/ new coatings
  • Process optimisation
    – Optimisation of material properties
    – Comparative process studies
    – Improved weld and joint quality
    – Economy and productivity (cycle times)
  • Automation
    – Post treatment methods
    – Non-destructive testing
    – Mechanised weld methods  

Industrial benefits in focus

The project scope is prioritised by the participating companies with industrial relevance as focus. Approximately ten researchers at Swerim work with projects related to joining technology, through the member program, national projects, and EU projects. The majority of the researchers are certified IWE (International Welding Engineer). Our expertise include:

  • Impact of joining method on material properties
  • Joint properties
  • Advanced materials
  • Joining of multi-material combinations
  • Joining of electrical components


  • Resistance Welding
  • Arc-welding (MIG/MAG, TIG, PAW, SAW)
  • Laser welding
  • Mechanical joining methods (FEW, SPR, FDS)
  • Friction Stir Welding (FSW)
  • Hybrid welding
  • Cladding, including DED

Swerim also offer expertise related to material characterisation, static and dynamic testing, virtual design, manufacturing, corrosion properties and accident investigation, among other relevant fields.
