  1. 1. A Framework for optimised welding of fatigue loaded structures : Applied to gas metal arc welding of fillet welds

    Författare :Erik Åstrand; Gunnar Bolmsjö; Fredrik Sikström; Heikki Remes; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GMAW; Fatigue; Welding procedures; Fillet welds; Weld quality; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Welding is a key process for heavy steel structures, but it is also a weak link in the structure since fatigue fractures in welds are a common cause of failure. This thesis proposes several changes in order to improve the fatigue properties in acost effective way, enabling reduced weight and reduced cost of welded structures. LÄS MER
