In this study, the method for calculating nominal structure stress of the spot-welded structures which authors developed was expanded, and the method to calculate nominal structure stress of the arc-welded structures was proposed. The finite element model of arc welding was made in order to obtain general loads and node displacements as a necessity for the nominal structure stress calculation. General loads and node displacements were well obtained in this model, and the excellent nominal structure stress was obtained as the result. Then, it was shown that the fatigue life prediction in the arc-welded structure was possible using this nominal structure stress.
