Fatigue tests were performed on corner welded joints to investigate the effective factors such as jointing method and leg length of weld. The material used was a structural carbon steel (S35C, 32mm in thickness). Three type of corner welded joints were chosen as follows, fully lap (type B), half lap (type A) and non lap (type C) corner fillet joints with various leg length. Fatigue tests were carried out under completely reversed plane bending stress at frequency of 1650cpm. The results were confirmed by FEM stress analysis. The following conclusions are obtained. (1) The welded joint of type C shows the highest fatigue strength under cyclic bending stress and the next is type A. (2) The above results are mainly affected by leg length of welds. (3) It was found from the FEM stress analysis that the optimum leg length of these corner welded joint was about 80 percent of plate thickness.
