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