Stirpower FSW Machines
Efficiency and quality right from the startOur FSW machines are far more than just welding systems – they are fully integrated production solutions. The maximum process stability is complemented by our specially developed clamping and fixture concepts, which secure components safely, flexibly and reproducibly, even under high forces and with complex geometries. Equally crucial is the FSW process control: with our bespoke tools, we lay the foundation for optimum weld seam quality with maximum tool life. This creates the foundation for stable processes, first-class joints and the shortest cycle times. The result: production-ready complete solutions that integrate seamlessly into your manufacturing and create productive added value from day one – without long ramp-up phases, but with immediate added value in your production. Equipped as standard with our STIRlytics quality software, you retain full oversight of every step of your FSW processes. You monitor welding parameters in real time, analyse measurement data and immediately identify deviations or potential for optimisation. The software comprehensively documents every production step, enabling full traceability of every single weld seam. This ensures reproducible quality, reduces scrap and minimises rework. At the same time, your series production becomes predictable, efficient and reliable, without compromising on performance or safety.
