  3. 22. Robotic Friction Stir Welding for Flexible Production

    Författare :Jeroen De Backer; Gunnar Bolmsjö; Giorgos Nikoleris; Anders Robertsson; Högskolan Väst; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 23. Feedback Control of Robotic Friction Stir Welding

    Författare :Jeroen De Backer; Gunnar Bolmsjö; Anna-Karin Christiansson; Jorge Dos Santos; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Process automation; Temperature control; Force control; Deflection model; Robotics; Svetsning; FSW; processtyrning; temperaturstyrning; robot; utböjning; kraftstyrning; Industriell arbetsvetenskap; Industrial engineering; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : 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.

  5. 24. Analysis and Monitoring of Laser Welding and Surface Texturing

    Författare :Rickard Olsson; Alexander Kaplan; John Powell; Jan Frostevarg; Michael Zäh; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; monitoring; Signal processing; laser texturing; texture analysis; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis can be conveniently divided into three sections as follows;Part I. Monitoring of laser welding In laser materials processing there has always been a need for suitable methods to supervise and monitor the processes on-line, to ensure correct production quality or to trigger alarms when failures are detected.

  7. 25. Automatic Quality Monitoring in GMA Welding using Signal Processing Methods

    Författare :Stefan Adolfsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; F; Signal Processing; Automatic Quality Monitoring; GMA welding; Materiallära; materialteknik;

    Sammanfattning : An ongoing continuous process of automatization of the production lines is used in industry to reduce production costs. Automatization of quality control should be seen as part of a cost reduction process, as well as of quality control of the welding. LÄS MER
