STUDIES ON GRINDING AREA OF OUT-OF-PLANE GUSSET WELDED JOINTS FOR FATIGUE STRENGTH ENHANCEMENT

Abstract

Various studies have been performed on improving fatigue strength of out-of-plane gusset welded joints because their fatigue strength is low in the case of as-welded condition. Grinding welded joint toes with burr grinder is conventional method for fatigue strength enhancement. In this study, for the purpose of proposing appropriate grinding area for out-of-plane gusset joints, fatigue tests and FEM analyses have been performed.
