  1. 1. Laser welding of boron steels for light-weight vehicle applications

    Author : Karl Fahlström; Lars-Erik Svensson; Leif Karlsson; Jens Klaestrup Kristensen; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser welding; boron steel; high strength steels; strength reduction; brittle behavior; crack susceptibility; distortions; light-weight; quality; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Abstract : Laser beam welding has gained a significant interest during the last two decades. The suitability of the process for high volume production has the possibility to give a strong advantage compared to several other welding methods. However, it is important to have the process in full control since various quality issues may otherwise occur. READ MORE

  3. 3. Modelling of Electric Arc Welding : arc-electrode coupling

    Author : Alireza Javidi Shirvan; Isabelle Choquet; Håkan Nilsson; Alexei Heintz; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric welding; arc welding simulation; electrode; plasma; cathode layer; sheath; arc discharge; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Arc welding still requires deeper process understanding and more accurateprediction of the heat transferred to the base metal. This can be provided by CFD modelling.Most works done to model arc discharge using CFD consider the arc corealone. READ MORE

  4. 4. Enhanced heat transfer and tool wear in high-pressure coolant assisted turning of alloy 718

    Author : Nageswaran Tamil Alagan; Tomas Beno; Uta Klement; Anders Wretland; Mikael Olsson; Högskolan Väst; []

    Abstract : Heat generated in a machining process is a common and critical obstacle faced in today's manufacturing industries. The heat generated in the cutting zone has adirect negative influence on the tool life, which, in turn contributes to increasing the manufacturing costs. READ MORE

  5. 5. Imaging and analysis methods for automated weld inspection

    Author : Patrik Broberg; Tadeusz Stepinski; Högskolan Väst; []
