About Stirtec


Our know-how is based on years of scientific research combined with the successful implementation of various industrial projects. Our focus is on advising and supporting our customers from the product idea to the certified series production thoroughly and competently. Our highly specialized technologists as well as experienced engineers and project managers form the basis for rapid and successful implementation of the respective FSW-project.

Machines and manufacturing systems

Based on many years of experience and knowledge gained from a large number of FSW-applications, we develop and fabricate high-quality machine tools through to fully automated and interlinked production lines involving special-purpose FSW-systems. In all systems, high process-functionality, high system availability as well as productivity are significant development factors. All machines can be additionally equipped with a quality monitoring system for 100% reliable FSW-process control.


FSW-tools are the key for high-quality FSW-functionality. Therefore, an independent development and fabrication of high-grade FSW-tools are an essential core competence of our company. By means of an in-house developed MaXstir tool range, we are capable of offering standard and special tools that are precisely tailored to the respective FSW-application requirements. We have developed and specified our own tool materials in order to provide the highest possible tool and service lives for the individual application.

Service portfolio Stirtec


The founders of Stirtec GmbH are dealing with this novel welding technique since 2005. Within the framework of a research project, a FSW-laboratory has been established by Dr. Weinberger and DI Figner at the Institute of Materials Science and Welding at Graz University of Technology. The challenge was to perform scientific research on the innovative FSW-technology and to investigate its applicability for different materials. Based on this, diverse patents in the field of tools, FSW-applications, Friction Stir Spot Welding (FSSW) and FSW motor spindles have been developed.

From 2008, the team started to deal intensively with the industrial implementation of the FSW-technology. Thus, several industrial projects have been successfully developed and implemented.

On the basis of the outstanding successes and owing to an increased industrial interest in applying FSW as a welding method in the series production, Stirtec OG has been founded in 2010 as a spin-off of Graz University of Technology. The core portfolio comprised technological consultancy, feasibility studies, prototyping as well as development and fabrication of FSW-tools. During this phase, first FSW-specific machines have been developed.

The company Stirtec GmbH was eventually founded in 2013, where its business portfolio has been expanded by customized FSW-machining and special-purpose systems. Accordingly, Stirtec is able to offer its customers complete FSW-manufacturing solutions from the product idea to the certified series production from a single source.


Prospective clients of Stirtec are companies, who use welding and other joining processes for the manufacture of their products. Particular emphasis is placed on structures as well as for hybrid designs (multi-material structures) and lightweight constructions, where welds of high-quality are necessary.
