P92钢焊接接头超声波检测缺陷的分析

摘要

By judging from defects no need for record on steel welded joint in SA335-P92, the article elaborated the ultrasonic testing of new martensitic steel. Experiments showed that the defect should be analyzed to determine whether it was between the sentence line and quantitative line, or below the evaluation line.%通过对新型马氏体耐热钢SA335-P92钢焊接接头中可不记录缺陷的再判定,来阐述该钢的焊接接头超声波检测的技术.试验表明,对按标准判定的缺陷,不管它是处于判废线与定量线之间,还是在评定线以下的缺陷,都应加以分析后判定.
