ON THE FATIGUE CHARACTERISTICS OF THE WELDED JOINT WITH SOFTENED AREA AT HEAT AFFECTED ZONE

The authors had reported that a TMCP steel plate with a carbon equivalent below 0.35 to 0.4% develops the softened area at its weld heat affected zone, and that the side welded joint with the softened area has the tensile strength the same as that of the base metal. It became clear from a design viewpoint that the fatigue strength of the welded joint with the softened area is almost the same as that of the welded joint free of the softened area. The authors had investigated notch sensitivity of a softened area to the base metal and the propagation behaviour of fatigue crack propagates through the softened area of the welded joint. The results had shown that the softened area has a lower notch sensitivity than the base metal and that the propagation rage of fatigue crack goes down or suspends for a while at the softened area.
