  1. 41. Welding of Heavy Structures Subjected to Fatigue

    Författare :Erik Åstrand; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Weld quality; Fillet welds; Weld procedures; Fatigue; Welded applications.; GMAW;

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