IMPROVEMENT OF FATIGUE STRENGTH OF TUBULAR T-JOINT IN OFFSHORE PLATFORMS DUE TO POSTWELD TREATMENT

摘要

Improvement of the fatigue life of welded tubular T-joints in offshore platforms due to weld toe grinding and TIG dressing is studied physically and experimentally. It is shown that the two methods of treatment can improve the fatigue strength of welded tubular joints not only in the environment of air but even in the environment of seawater accordingly.
