In the previous studies, plate bending fatigue tests were conducted on a steel plate with stud bolt welded upward, and the fatigue limit was less than the fatigue strength class of E in JSSC. This might be caused by the upward welding, however, the fatigue limit of the stud welding itself might become low. In this study, in order to clarify the fatigue limit of stud welded joints, plate bending fatigue tests were carried out. As a result of the fatigue tests, the fatigue limit varied depending on the diameter of the studs, and the fatigue cracks were observed in the plate bending fatigue test under the stress range of fatigue strength class E.
