  2. 11. Laser welding of ultra-high strength steel and a cast magnesium alloy for light-weight design

    Author : Karl Fahlström; Lars-Erik Svensson; Leif Karlsson; Michael Rethmeier; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; ultra-high strength steel; cast magnesium alloy; light-weight design; automotive industry; distortion; porosity; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : There is a strong industrial need for developing robust and flexible manufacturing methods for future light-weight design. Better performing, environmental friendly vehicles will gain competitive strength from using light weight structures. READ MORE

  4. 12. Laser-welded corrugated core steel sandwich panels for bridge application

    Author : Peter Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear stiffness; corrugated core; laser-welding; joint geometry; sandwich panel;

    Abstract : The design of steel bridge decks has remained unchanged since the introduction of orthotropic decks. Orthotropic decks are expensive to produce, mainly due to high labor-costs. READ MORE

  5. 13. Technical development of the laser welding process

    Author : Klas Nilsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This thesis describes the technical development of the laser welding process and presents the results from a number of experimental investigations. The seven papers that make up the thesis investigate various aspects of the technical development of the laser welding process mechanism as well as industrial applications. READ MORE

  6. 14. Directed Energy Deposition Additive Manufacturing and Welding of Duplex Stainless Steel using Laser Beam

    Author : Amir Baghdadchi; Leif Karlsson; Joel Andersson; Vahid Hosseini; Dirk Engelberg; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; Laser welding; Additive manufacturing; Direct Energy Deposition using a Laser Beam; Microstructure characterization; Duplexa rostfria stål; Lasersvetsning; Additiv tillverkning; Metalldeponering med laser; Mikrostruktur; Production Technology; Produktionsteknik;

    Abstract : Duplex stainless steels (DSSs), with a ferritic-austenitic microstructure, are used in a wide range of applications thanks to their high corrosion resistance and good mechanical properties. However, efficient and successful production and joining of DSS require precise control of processes and an in-depth understanding of the relations between composition, processing thermal cycles, resulting microstructures and properties.

  7. 15. Inductive measurement of narrow gaps for high precision welding of square butt joints

    Author : Edvard Svenman; Anna-Karin Christiansson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : A recent method in aero engine production is to fabricate components from smaller pieces, rather than machining them from large castings. This has made laser beam welding popular, offering high precision with low heat input and distortion, but also high productivity. READ MORE
