Large scale specimens of transverse fillet welded joints which were assembled using thicknesses and shapes similar to those of the actual structures, and the improved weld electrodes were tested. Specimens were cruciform welded joints, box-section and H-section members of 600MPa, 800Mpa and 500MPa class steels. Effects of stress ratios, weld toe profiles, scallops and single-side fillet welding of the end diaphragm on the fatigue strength of joints were examined.
