Abstract

Abstract

DING prevention technology used in the local heat treatment of the circular welds on AP1000 steam generator is a new technique different from that for the second generation SG. This paper briefly introduces the causes for DING, influencing factors and prevention measures, and provides the key check points in the process of the quality supervision.
