THE EXPERIMENTAL STUDY FOR FATIGUE BEHAVIOR OF WELD LINE BY THIRD TIG-DRESSING

摘要：

In this paper, the third TIG-dressing technology is used for the weld-line after secondary TIGdressing and its fatigue life is higher in high stress region. But the fatigue life after third TIGdressing is decreased in low stress region. The effects of third repairing weld and TIGdressing on the fatigue property of high strength steel weld joints used in platform have been investigated. The life estimating formula is obtained after third repairing weld and TIGdressing. The S-N curve and the equation after third TIG-dressing are given.
