FSW technology –

Friction stir welding

High-strength joints without melting – for demanding applications

Friction stir welding (FSW) is an innovative and particularly environmentally friendly welding process in which materials are joined together in a solid state. It is ideal for aluminum alloys, but also for joining different materials that are difficult to join using conventional welding methods.

The purely mechanical connection – without a weld pool – produces virtually flawless, dimensionally stable and high-strength weld seams that can withstand even high loads and extreme requirements. FSW is therefore the ideal solution for safety-relevant components and modern lightweight construction applications – e.g. in e-mobility, aviation or mechanical engineering.

Your advantages with FSW at a glance:

Highest connection quality

  • Pressure and media-tight weld seams
  • High strength and load-bearing capacity
  • No pores, hot cracks or spatter – as no liquid phase is created
  • Reproducible quality with every seam
  • Low distortion, precise results

Environmentally friendly & harmless to health

  • Emission-free process – no smoke, no gases, no noise
  • No additives such as shielding gases, powder or welding rod required
  • No radiation – no exposure for employees
  • Energy-efficient and resource-saving

Typical areas of application:

  • Joining all types of aluminum alloys
  • Joining heterogeneous materials (e.g. aluminum-copper)
  • Components with the highest demands on tightness & stability
  • Central production technology for e-mobility:
    → e.g. battery trays, cooling plates, heat exchangers
