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

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

    Sammanfattning : 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. LÄS MER

  7. 10. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding

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

    Sammanfattning : 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. LÄS MER
