StiRoLight - Robotic Friction Stir Welding - FFI project

This movie was made by University West and partners to demonstrate research on the process Friction Stir Welding and how it can be automated. In this process a rotating tool moves forward between two plates that are in contact with each other. The metal is not melted as in ordinary welding, but it softens due to the frictional heat so that the plates fuse. The many advantages with the method are explained in the movie. Friction Stir Welding is shown on an aluminum hood structure of a car that is being built. Simulation and programming techniques are also demonstrated. Findings of the research make clear the feasibility and applicability of Robotic Friction Stir Welding in automotive and similar products. This can make cars lighter and reduce greenhouse gas emissions.
The StiRoLight research project was funded by Vinnova, within the FFI program. Partners in the project have been Volvo, University West, SAAB Automobile, Innovatum Teknikpark and ESAB. Great work by all partners!
