Study on Creep Behavior Evaluation of Welded Joint (Report II)

Internal Pressure Creep Behavior of Cylindrical Specimen with Circumferential Welded Joint

Abstract

Creep properties of thin wall tubes with a circumferential joint subjected to high temperature internal pressure have been discussed experimentally and analytically. From the results, a method of evaluating the creep rupture property of the tube from the creep data of weld metal and base metal has been proposed. And, the creep rupture properties of Hastelloy X thin wall tubes with TIG welded joint and EB welded joint by internal pressure have been evaluated by the above method.
