Research Abstract

For improving the fatigue strength of welded joints, introducing the residual stress at weld toe by peening is often used. If a compression overload is subjected after peening, however, the residual compressive stress at weld toe will shift the tensile stress region. Therefore, the improved fatigue strength by residual compression stress at weld toe will be reduced after the compression overloaded. In this research, the effect of compression overload on fatigue strength improved by residual compression stress was clarified by the plate bending type of fatigue tests.
