FATIGUE CRACK PROPAGATION THROUGH WELD HEAT AFFECTED ZONES

Fatigue tests were performed on specimens containing weld heat affected zones at two orientations to the stress axis. Two steels were used, one a low alloy steel and the other a mild steel. It is stated that, since the tests were performed on actual heat affected zones under known stress conditions, the conclusions can be applied to the behavior of fatigue cracks in actual structures under operating conditions. The observations suggest that, when fatigue cracks are present, the integrity of a welded structure may depend on the toughness of the component with the lowest flow stress.
