Robot-assisted friction-stir-welding systems

Highly flexible in three dimensions

With its robot-assisted friction-stir-welding systems, Grenzebach has opened completely new areas of application for FSW technology. Welding robots already support numerous applications in industrial 24/7/365 series production; they can also be used in research and development, and for working on prototypes and small batch series.

Active power control combined with robot kinematics not only allows for FSW’s 3D capacity but also makes it possible to weld awkwardly placed parts, such as those in horizontal-vertical positions. With our CAD/CAM programming system, even complex welding lines and parameters can be handled without problems.

  • Higher-level process and system control ensures process stability
  • Working range DSR2000: R 1.295 mm – 2.675 mm; (X/Y plane) Z 3.371 mm
  • Two workstations for loading in parallel during production ensure efficient production

R&D FSW Systems

Welding even the thinnest aluminum, or welding a mix of materials with low distortion, media-tight and outstanding surface quality: this is by no means all that friction stir welding can do. Grenzebach’s systems are an ideal way for you to discover the future of FSW technology in the course of research and development.

We offer DSR robots (DSR = Dynamic Stirring Robot) in special designs for research facilities. With full functionality and top quality, our R&D facilities offer optimal space and accessibility to all the measuring equipment.

Reliable, complete recording of all process-relevant machine data is a matter of course. The CAD/CAM feature allows maximum flexibility when it comes to changing the test setup or object. In special cases, our technical support provides reliable assistance. We see ourselves not only as a technology expert and robot manufacturer, but also as a discussion partner for all your questions.

Easy to expand and convert

Combine your R&D robot cells the way you want with welding tables, measuring equipment and media feeders. There are no limits to the possibilities for discovery and experimentation. The equipment depends on your questions – your needs.

Flexible use

Discover the possibilities with FSW: which materials and components can be welded? In addition to a wide range of applications in the automotive industry, friction stir welding is also being used increasingly frequently in consumer electronics and the construction industry. For example, FSW robots join formed aluminum sheets for rooftop solar collectors that harness the power of the sun for energy.

Very reliable

FSW cells are designed for 24/7 use. Our robotic systems are highly robust and resilient, so they’ll always be able to handle new problems.
