The influence of blowholes on the fatigue strength of members with longitudinal welded joints was investigated by probabilistic approach. Random variables and parameters used were blowhole size, member length, probability of fatigue crack occurrence from blowholes, distribution of stress range and parameter C in Paris's law. Probabilistic functions of these variables were given from the results of previous fatigue tests or field measurements. By parametrical analysis, the influences of the above random valiables on the fatigue strength of longitudinal welded joints were evaluated quantitatively.
