  2. 1. An inductive gap measurement method for square butt joints

    Author : Edvard Svenman; Anna-Karin Christiansson; Anna Runnemalm; Johan Carlsson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy current; Seam tracking; Measurement; Laser beam welding; gap geometry; 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

  5. 3. Improving fatigue properties of welded high strength steels

    Author : Ebrahim Harati; Lars-Erik Svensson; Leif Karlsson; Norbert Enzinger; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue strength; Residual stress; Welds; Weld toe geometry; High strength steel; High frequency mechanical impact treatment; Low Transformation Temperature welding consumable; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Abstract : In recent years a strong interest has been expressed to produce lighter structures.One possible solution to reduce the weight is to utilize high strength steels and use welding as the joining method. READ MORE

  6. 4. Processability of Laser Powder Bed Fusion of Alloy 247LC : Influence of process parameters on microstructure and defects

    Author : Olutayo Adegoke; Joel Andersson; Robert Pederson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser powder bed fusion; Alloy 247LC; additive manufacturing; nickel-based superalloys; processability; cracks; voids.; Production Technology; Produktionsteknik;

    Abstract : This thesis is about laser powder bed fusion (L-PBF) of the nickel-based superalloy: Alloy 247LC. Alloy 247LC is used mainly in gas turbine blades and processing the blades with L-PBF confers performance advantage over the blades manufactured with conventional methods. READ MORE

  7. 5. Exploring sustainable manufacturing principles and practices

    Author : Claudia Alayón; Kristina Säfsten; Glenn Johansson; Anna Granlund; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable manufacturing principles; sustainable manufacturing practices;

    Abstract : The manufacturing industry remains a critical force in the quest for global sustainability. An increasing number of companies are modifying their operations in favor of more sustainable practices. READ MORE
