Abstract

This paper reported x-ray residual stress measurements of a large spherical vessel with cracks. The first measurement was taken for defect analysis, and the second and third were taken for evaluating the effect of local heat treatment on reducing residual stresses. Furthermore, in order to evaluate further run of the vessel, applied stresses were obtained using strain gauge during hydraulic test.
