概要

Japanese code for ultrasonic testing in-service inspection, named JEAC 4207, allows inspection through weld metal, in case that some factors, such as weld crown or other structures, disturb scanning. The applicability of through weld metal inspection had been reported with BWR piping. This paper will be technical basis of applicability of through weld metal inspection for PWR piping, which is thicker and has factor hardens inspection. The data successfully shows the capability for detection and sizing by through weld metal inspection.
