摘      要：正 Three steel materials used widely in Chinese industry[l] have been chosen to study the fatigue characters of welded structures under various *** on the fatigue testing results that correspond to different stress ratios,loading methods,and dimensions of the welded joints,the relations among these influential factors are obtained mat may help predict the fatigue lives under an actual *** addition,the stress analyses are also made to find out the influence of the shape of a welding line on the fatigue life of a welded joint
