The Study of Fatigue Life of the Crack of Weld Bead

Abstract:

Article Preview

The effects of multiple repairing-weld and TIG-dressing on the fatigue property of high strength steel weld joints used in platform have been investigated. Through the fatigue tests on high strength steel welded joint samples, the life estimating formula is obtained after each time of repairing weld and TIG-dressing. The S-N curve and the equation after repairing weld and TIG-dressing are given. The work in this paper offers an important basis for the multiple repairing-weld of platforms.
