This paper is concerned with the influence of a notch root radius at the weld toe and TIG treatment on fatigue properties of welded high strength steel. In general, it has been considered that small notch radii at the weld toes are responsible for low fatigue strength of welded joints. However, the fatigue limit of a welded joint usually does not depend on the notch root radius of the weld toe because of the existence of a non-propagating fatigue crack. In most cases, the fatigue limit of the welded joint is determined from the notch root radius at the branch point which is a material constant. The beneficial effect of TIG treatment on fatigue properties differs according to the value of mean stress. This result is explained by the characteristic fatigue behavior of notched specimens.
