摘要

对湖南省某些火电厂除氧器水箱焊缝裂纹表现特征进行了分析。同时

讨论了这种裂纹的性质和扩展模式

以及引起这种裂纹的原因。分析认为这种裂纹属于腐蚀疲劳的范围

具有应力腐蚀疲劳的特征。

Abstract

In view of the present situation of widespread welding joint cracks in dearator water tank at thermal power plants

the occurence and feature of said cracks in some power plants of Hunan Province have been analyzed

at the same time

the nature and extension mode of said cracks are discussed

and the reason causing the said cracks is analyzed as well. It is considered that the said cracks belong to the corrosion fatigue range

featuring stress corrosion fatigue.
