Tool for friction stir welding with setting device
A recently granted patent (Publication Number: US11845142B2) discloses a tool for friction stir welding designed to join panel elements pre-fabricated from a weldable material. The tool comprises a central axle connected to friction shoulders and support shoulders, with a setting device exerting force on the support shoulders during use. The setting device, driven by centrifugal forces, applies pressure on the support shoulders towards the adjacent friction shoulders, facilitating the welding process. The tool's design allows for precise and efficient friction stir welding, ensuring a strong bond between the panel elements.
Furthermore, the patent also details a method for producing panels using the described tool. The method involves joining panel elements with recesses to form a tunnel, with the tool acting as a welding pin guided along the joining seams. The friction shoulders of the tool work on the top and bottom surfaces of the panel elements, while the support shoulders are pressed against the material sections forming the joining seam. The method, particularly suitable for light metal materials, ensures a high-quality weld by subjecting the material sections to friction stir stress. Overall, the patented tool and method offer a reliable and effective solution for friction stir welding applications, especially in the production of panels with precise joining seams.
