FATIGUE OF STEEL WELDMENTS
THE LITERATURE DEALING WITH THE FATIGUE OF STEEL WELDMENTS HAS BEEN REVIEWED AND THE EFFECT ON FATIGUE STRENGTH OF TESTING CONDITIONS, WELD GEOMETRY, WELD METAL SOUNDNESS, RESIDUAL STRESS, AND THE MICROSTRUCTURE OF THE WELD METAL AND HEAT-AFFECTED ZONE HAS BEEN EXAMINED. IT HAS BEEN CLEARLY SHOWN THAT WELD GEOMETRY IS THE MOST IMPORTANT FACTOR IN DETERMINING THE FATIGUE PROPERTIES OF A WELD. FOR A GIVEN WELD GEOMETRY, THE FATIGUE STRENGTH IS DETERMINED BY THE SEVERITY OF THE STRESS CONCENTRATION AT THE WELD TOE OR, WITH THE WELD REINFORCEMENT REMOVED, BY THE STRESS CONCENTRATION AT WELD METAL DEFECTS. DIFFERENT WELDING PROCESSES INFLUENCE FATIGUE STRENGTH BY PRODUCING WELDS WITH DIFFERENT DEGREES OF SURFACE ROUGHNESS AND WELD METAL SOUNDNESS. /DOT/
