  1. 16. The Morphology of Laser Arc Hybrid Welds

    Författare :Jan Frostevarg; Veli Kujanpää; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : This thesis is about formation of surface imperfections formed in welding when using the manufacturing methods of laser welding and laser arc hybrid welding. In hybrid welding a traditional arc welding source and a laser share the same melt pool, making the process even more complex. LÄS MER

  3. 17. In-situ analysis of process characteristics in Directed Energy Deposition

    Författare :Tobias Hauser; Alexander Kaplan; Joerg Volpp; Barbara Previtali; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : In recent years, the interest in Additive Manufacturing on an industrial scale has risen due to the various new processes and the increase in potential use cases. In this thesis, the two Additive Manufacturing processes, Wire Arc Additive Manufacturing and Laser Metal Deposition were investigated. LÄS MER

  5. 19. Production simulation as a management tool

    Författare :Torbjörn Ilar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsutveckling; Manufacturing Systems Engineering;

    Sammanfattning : This thesis focuses on process simulation and modelling in the context of production engineering. The thesis is presented in the form of seven papers which range in content from the holistic analysis of the application of modelling (papers 1-5) to a detailed examination of some of the areas of weaknesses in commercially available software (papers 6 and 7).

  7. 20. Two laser welding cases and suitable documentation methods

    Författare :Jan Karlsson; Luisa Coutinho; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : The thesis is about laser welding, in particular about geometrical defects, but it also addresses how to improve the documentation of the findings. Laser welding is an important and highly advanced manufacturing technique in industry. An emerging option is laser hybrid arc welding. LÄS MER
