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.

Double in the loop - Refill friction stir spot welding developed
18.12.2023
Stir4Steel successfully managed to developed a smart refill friction stir spot welding solution for various material combinations. To make it happen required material surface pre-treatments as well as required process windows have been elaborated and tested. Evaluation of these tests, such as metallurgical, mechanical, and surface properties including for both single-spot and multi-spot joint configuration, show promising results. Want to know more?
