  2. 1. 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

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Applied Materials Technology; friction stir welding; fatigue; mechanical properties; welding speed; softening; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Solid state Friction stir welding (FSW) is of major interest in the welding of aluminium since it improves the joint properties. Many applications where Al-alloys are used are subject to varying load conditions, making fatigue failure a critical issue. READ MORE

  6. 4. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding

    Author : Wallop Ratanathavorn; Arne Melander; Gunnar Bolmsjö; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloy; high strength steel; intermetallic; friction stir welding; dissimilar joining; SRA - Produktion; SRA - Production;

    Abstract : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. READ MORE
