Abstract

Fatigue tests and stress analyses have been performed on specimens modeling web-gusset welded joints, which are as-welded and finished with burr-grinders or disc-grinders. Based on the above experimental and analytical results, fatigue strength category is proposed as to types of grinder and finishing method applied. Furthermore influences of weld toe radius, fillet radius, depth of ground area and plate thickness on stress concentration are made clear through three dimensional finite element stress analyses.
