  2. 1. Fatigue properties of cut and welded high strength steels : Quality aspects in design and production

    Author : Thomas Stenberg; Zuheir Barsoum; Kenneth Alasdair MacDonald; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; Fatigue assessment; Cutting; Weld quality; Fatigue design; Fracture Mechanics; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : This doctoral thesis concerns fatigue of welded structures. Welding is one of the world’s most common joining methods and it is frequently used in several structural applications in many fields. Some examples are construction vehicles, loader cranes, trucks, busses, forestry and agricultural machines, bridges and ships. READ MORE

    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

  6. 4. Timber volume element prefabrication : production and market aspects

    Author : Matilda Höök; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Problems discussed within the Swedish housing industry are lack of competition, quality and increased costs. Improvements to cope with these problems have shown to be low compared to manufacturing and other industries. READ MORE
