    Abstract : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

  2. 2. Robot system for flexible 3D friction stir welding

    Author : Mikael Soron; Ivan Kalaykov; Jorge F. dos Santos; Örebro universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding; robotics; TECHNOLOGY; TEKNIKVETENSKAP; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Abstract : Applying Friction Stir Welding (FSW) on complex joint geometries requires not only a machine with 3-dimesional work space capacity, but also a sound definition of the part geometry as well as knowledge about the process. Having a joining process, such as FSW, with great characteristics from both seam quality and environmental perspective, but yet only a minor presence in the manufacturing industry may be related to flexibility and cost issues.

  3. 3. Robotic Friction Stir Welding for Flexible Production

    Author : Jeroen De Backer; Gunnar Bolmsjö; Giorgos Nikoleris; Anders Robertsson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding; Automation; Robotics; Aluminium; Lightweight design; Industriell arbetsvetenskap; Industrial engineering; Mechatronics; Mekatronik;

    Abstract : Friction Stir Welding (FSW) is a modern welding process that joins materials by frictional heat, generated by a rotating tool. Unlike other welding processes, the material never melts, which is beneficial for the weld properties. READ MORE

  4. 4. Friction Stir Welding of Copper Canisters Using Power and Temperature Control

    Author : Lars Cederqvist; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; copper; temperature control; PID control;

    Abstract : This thesis presents the development to reliably seal 50 mm thick copper canisters containing the Swedish nuclear waste using friction stir welding. To avoid defects and welding tool fractures, it is important to control the tool temperature within a process window of approximately 790 to 910°C. READ MORE
