Tooling technology

The tooling is essential

Regardless of the application: Besides the system technology the tooling is decisive for the process and therefore the success of FSW. The wear-resistant and robust FSW tools are developed according to specific requirements exclusively by Grenzebach’s experts. By means of a holistic Grenzebach solution, nothing is left to chance. With regard to the tool, one has to differentiate between the one-piece (conventional) and the multi-part tools (DynaSTIR) in friction stir welding: Both of these are in our portfolio!

 

The process development for the specific customer application as well as the provision of customized tools is part of our holistic approach.

 

  • The welding system, the process parameters and the welding tool always optimally match each other, this creates the best possible connection quality.
  • We attach highest importance on a close cooperation with the customer during the design of the joining concept.
  • Grenzebach supports in FSW-compliant design of the module during the design phase of components.
  • Test and prototype welding as well as contract manufacturing orders are possible on the proprietary FSW systems of Grenzebach.

The DynaSTIR tools enable extremely gentle and filigree processing of materials.

  • Reduction of process forces by up to 50 percent

  • Thin sheet applications with material thicknesses < 1.0 mm possible

DynaSTIR tooling technology

  • Welding tool out of rotating pin and non-rotating shoulder
  • Shoulder slides without rotation over weld
  • Significantly reduced process forces
  • High track dynamics
  • Individual parameter setting of pin and shoulder
  • Shoulder geometry adaptable to joint geometry
  • Low heat input
  • Individual of pin and shoulder possible
  • Welding penetration depth individually adjustable

Conventional tooling technology

  • One-pieced rotating welding tool
  • Ideally suitable for high speed of welding and high penetration depths

The welding tools have a significant impact on welding quality. We develop the tools exactly according to the customer's requirements.

  • Project specific selection and customization

  • Welding penetration depth for Al alloys up to 8 mm

  • Welding speed up to 3m/min in serial production
