History – Founder Thomas Weinberger and Gunter Figner
The founders of Stirtec have been developing and expanding the knowledge within the solid-state welding technique Friction Stir Welding since their early academical studies in year 2005. As part of the research focus, Dr. Weinberger and DI Figner set up an innovative Friction Stir Welding laboratory at the Institute of Materials Science and Welding Technology on the University of Technology in Graz, Austria. Their scientific research implements the analysis on the FSW technology for different material joints and applicability for industrial use within the automotive industry. On-going from this passion for Friction Stir Welding, the company Stirtec was founded in year 2010 as a spin-off of the University of Technology in Graz with multiple patents in the development of the designated tooling, typical applications for processing and design on the sufficient machine equipment.
