Rotary friction welding machines

KUKA and Thompson friction welding machines make the industrial joining of a broad range of materials simple and cost-effective. You can even weld challenging and safety-relevant material combinations with high quality in technology trends such as e-mobility and lightweight construction.

Two brands, one strong partner to cover different industries with tailor-made and standard solutions.

Over 50 years ago, KUKA established rotary friction welding as an industrial joining process. The product portfolio of KUKA welding machines was expanded in 1994 with the takeover of machine manufacturer Thompson Friction Welding (UK). Since then, KUKA has been one of the global market leaders in this field with more than 1,200 rotary friction welding machines installed in over 44 countries.

Rotary friction welding technology: economical and safe joining of different materials and material combinations

KUKA friction welding machines weld metallic workpieces such as piston rods, valves or heat exchangers.

Advantages of KUKA and Thompson rotary friction welding machines

The high-tech machines set standards in terms of precision, dynamics, process control, and productivity.

  • Maximum cost reduction

    Limit use of expensive material to those points that are relevant for the component. 
  • Wide variety of material combinations

    Confirmed weldability even of demanding combinations such as aluminum and copper
  • Utmost availability

    Low maintenance thanks to high-quality components and durable machine technology
  • Maximum welding quality

    High quality results thanks to validation of each workpiece
  • Maximum traceability

    Detailed documentation and archiving of process data via KUKA PCD (Process Control and Documentation)
  • Highest ergonomics

    Intuitive touchscreen operation and ergonomically designed workspace
With our unique KUKA Tech Centers at Augsburg (Germany) and the Thompson welding competence centre in Halesowen (UK), we are able to test the practical viability of the innovative concepts of tomorrow. We also offer additional services, such as process validation, prototype construction or small series, or take care of the entire manufacturing process in multiple-shift operation.

Machines custom-tailored to your needs

KUKA has various rotational friction welding machines in its product portfolio with a forge force between one and 10,000 kilonewtons. This range covers even the most difficult components. Whether you opt for our new, compact and universal Genius series or special machines for particular components – the range of machines offers two different design types that are tailored to your requirements. Special sizes and designs, such as double-spindle machines and machines of vertical design, are available on request.
