FATIGUE TEST JIG FOR WELDED JOINT

摘要

PROBLEM TO BE SOLVED: To provide a weld fatigue test jig by uniformizing left and right stress distributions in a test piece of a welded joint wherein left and right parallelism does not appear because of having a weld deformation or optional attaching angle. SOLUTION: When a welded T joint 2a wherein a difference is generated in left and right parallelism of an angular deformation owing to a weld deformation is chucked by a fatigue test jig 1, the difference between left and right parallelism is dissolved by preparing and setting pin jigs C5 whose diameter differ by a size equivalent to the difference between left and right parallelism, a stress distribution in a weld toe part becomes uniform and fatigue test data having high reliability are obtained.
