    Sammanfattning : The overall aim of this thesis is to explore the theoretical and empirical relationship between entrepreneurship and bureaucracy, and to examine the cause and effect of entrepreneurship. From this overall aim, four specific questions are investigated. LÄS MER

  4. 4. Process planning of resistance spot welding

    Författare :Oscar Andersson; Arne Melander; Lars-Erik Svensson; KTH; []
    Nyckelord :;

    Sammanfattning : Manufacturing engineering in general has experienced an increased demand of process planning in order to optimize processes to reduce costs, environmental impact and increase time efficiency. Resistance spot welding (RSW) is a common and large-scale joining method in several manufacturing industries indicating significant potentials of efficient process planning. LÄS MER

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

    Författare :Karl Fahlström; Lars-Erik Svensson; Leif Karlsson; Jens Klaestrup Kristensen; Högskolan Väst; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Sammanfattning : 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. LÄS MER
