FATIGUE BEHAVIOR OF WELDED JOINTS AND WELDMENTS IN HY-80 STEEL SUBJECTED TO AXIAL LOADINGS
Abstract
Axial load fatigue tests on various types of welded joints and weldments in HY-80 steel are reported. The tests were carried out using three stress cycles; complete reversal, zero-totension, and half tension-to-tension. Most of the test lives lie between 2,000 and 600,000 cycles. These results have been used to develop Modified Goodman diagrams. A preliminary series of fatigue tests was carried out to study the effects of interpass temperature, lack of penetration, type of electrode, and longitudinal fillet welded attachments. When the specimens of a given test series failed due to an internal flaw, there was often a large amount of scatter in the test lives at a given stress level. Apparently internal weld flaws have a significant effect on the fatigue behavior of a welded joint. (Author)
