Stirtec GmbH is a leading high-tech company in the field of Friction Stir Welding (FSW), located in Premstätten, Styria (Austria). Stirtec was initially established in 2010 as a spin-off of Graz University of Technology in the Science Park Graz to exploit the commercial potential of the Friction Stir Welding technology for industrial applications. Based on more than 10 years of scientific research resulting in five patents, and together with the successful implementation of various industrial projects in close customer cooperation, Stirtec is now a leading solution provider in the field of FSW.
As a pioneer for joining so far nonweldable metals (dissimilar materials, such as steel and copper and high strength steels), the company is offering machines, software and tools for demanding applications to European and US customers. Stirtec has established an initial client base of satisfied reference customers in both the transportation and industrial sectors, securing high trust in the company. Stirtec wants to be the clear market leader in Europe for friction stir welding for industrial applications, serving globally active customers.

First Glance of Industrialization - 04.08.2023
Outlook for the Bodyside B-Pillar
The industrialization simulation for the B-Pillar being part of D 6.1 allows the first results inside the Stir4steel project, the concept is a typical car bodyside geometry with the exceptional feature of having dissimilar material joining (Aluminum and Galvanized steel), the solution based on the Refill Friction Stir Spot Welding and the latest development on the Stir4steel project testing, demonstrate the feasibility of the industrialization of the assembly following the automotive body in white standards.
The FSSW guns by STIRTEC offers the same flexibility as standard Resistance welding guns and can be installed in a standard 6-axis robot and customized to the shape of the stamped part.
A complete welding process is being designed and simulated using SIEMENS Process Simulate software to demonstrate the feasibility.
