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.

Outsmart corrosion – 10.04.2022
a key challenge for dissimilar refill friction stir spot welding
In a bid to enhance the corrosion resistance of dissimilar refill friction stir spot welding (RFSSW) joints between aluminum and steel, a new strategy employing Dupont Betamate 1822 sealant has been implemented as detailed in D 1.4 . This innovative approach aims to address the potential vulnerability of such joints to corrosion, which can lead to structural integrity issues and reduced longevity.
The use of Betamate 1822 sealant in these joints provides several key benefits. Firstly, it fills any imperfections in the RFSSW joint, enhancing joint integrity and strength. Additionally, the sealant forms a durable protective barrier, safeguarding the joint against corrosive elements and prolonging its service life. Moreover, the sealant offers excellent adhesion to both aluminum and steel, ensuring compatibility with dissimilar materials used in the shock tower and B-pillar body structure application.
