To understand the relaxation behavior of compressive residual stress, out-of-plane gusset welded joints were treated using different peening methods. Compressive residual stress near the peened edge was measured using an X-ray residual stress analyzer while applying plate bending compression loads. The results showed that compressive residual stresses at 2 mm from the peened edge relaxed proportionally with increasing compression load. Strain measurements at the same location supported the estimation of stress relaxation behavior. Plate bending fatigue tests were then conducted under a stress ratio of R = 0.5. Fatigue strength decreased with increasing compression load, and under a 5.8 kN (approximately − 286 N/mm²), the fatigue strength approached that of as-weld. Finally, the fatigue results were evaluated using a newly proposed fatigue strength design curve with a cut-off limit for peening treatment, based on recommendations from the JSSC. It was concluded that this curve remains applicable if the applied compressive load after peening does not exceed 3.8 kN. Furthermore, continuous residual stress monitoring at the 2 mm confirmed that fatigue strength improvement remains effective as long as residual compressive stress is preserved during subsequent loading.
