Abstract
The creep rupture strength of TIG-welded Hastelloy X cylinders under internal pressure was remarkable lower than that of non-welded cylinders. In order to improve this strength, tests were performed on the cylinders welded by using various filler wires and welding procedures. The creep rupture strength of these cylinders were, to some extent, improved by using filler wires of Incoloy 800 or Hastelloy X with small boron content. Although the life of cylinders were comparable with that of cylinders without weld joint, several fine cracks were observed on the weld mteal and some of them were penetrated into the wall of the cylinders. The high creep rupture ductility of the weld metal was essential to achieve high reliablity in welded components served at elevated temperatures. The final target of the improvement in creep rupture ductility was discussed.
