To improve fatigue strength of fillet-welded joints by hammer-peening treatment, fatigue tests were carried out on three types of longitudinal out-of-plane gusset fillet-welded joints and transverse non-load carrying cruciform rib fillet-welded joints: as-welded joints, post-weld hammer peened joints and hammer peened joints at 50% of as-welded joint’s fatigue life. From the test results, the effect of hammer-peening treatment on fatigue behavior of the fillet-welded joints were presented
