  2. 1. 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

  4. 2. Investigation and modelling of friction stir welded copper canisters

    Author : Therese Källgren; Rolf Sandström; Hannu Hänninen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; SKB; Material flow; Materials science; Teknisk materialvetenskap;

    Abstract : This work has been focused on characterisation of FSW joints, and modelling of the process, both analytically and numerically. The Swedish model for final deposit of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. READ MORE

  5. 3. Development and evaluation of hybrid joining for metals to polymers using friction stir welding

    Author : Wallop Ratanathavorn; Arne Melander; Stefan Hallström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloy; thermoplastic; friction stir welding; dissimilar joining; Production Engineering; Industriell produktion;

    Abstract : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. READ MORE

  6. 4. Thermoelectric Measurements for Temperature Control of Robotic Friction Stir Welding

    Author : Ana Catarina Ferreira Magalhães; Gunnar Bolmsjö; Jeroen De Backer; Jean Pierre Bergmann; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Aluminium; Temperature measurements; Process control; Robotics; Geometrically complex components; Friktionsomrörningssvetsning; Aluminium; temperaturmätning; Processstyrning; Robotik; Geometriskt komplexa komponenter; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Friction stir welding (FSW) has undergone a rapid expansion in several industrial sectors such as in the aerospace, marine, railway and automotive sectors. Current industrial applications are mainly simple long straight welds, but there is a growth of interest in components with higher geometric complexity. READ MORE

  7. 5. Aspects of Heat Flow in Laser Processing of Metals

    Author : Jesper Sundqvist; Alexander F.H. Kaplan; John Powell; Andreas Otto; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Abstract : Since the laser was invented in 1960, its use in manufacturing industry has been growing rapidly. Laser processing of metals is based on the flow of heat that is generated by the absorbed laser beam. READ MORE
