The phased array ultrasonic test of pipeline girth weld

  • 摘要: 针对半自动焊及手工焊管道环焊缝相控阵超声检测(PAUT)提出了可靠性试验方法,设计制作了人工模拟自然缺陷,进行了PAUT、自动超声检测(AUT)等大量对比试验。通过宏观切片制作及样本统计学分析,建立了PAUT环焊缝缺陷检测的POD(Probability of Detection)曲线,以及定量能力评估的POS(Probability of Sizing)曲线,用实际数据分析了PAUT环焊缝检测的可靠性。数据结果表明,PAUT具有较高的检出率,95%置信度下达到90%检出率的缺陷尺寸为0.92 mm。采用-6 dB测高法得出的定量分析结果误差较大,误差平均值为2.94 mm,误差标准差为1.37 mm,定尺普遍偏大,离散性较大,定量方法仍需改进。
    Abstract: We have proposed a reliability test method for PAUT inspection of semi-automatically and manually welded pipe girth welds. Design and production of artificial simulation of natural defects and a large number of comparison tests such as PAUT and AUT were carried out. Through the macro slicing production and sample statistical analysis, the POD curve of the PAUT pipe girth welds defect detection and the POS curve of the quantitative ability evaluation were established, and the reliability of the PAUT girth weld inspection was further analyzed using actual data. The data results show that the PAUT has a high detection rate, the defect size of 90% detection rate at 95% confidence is 0.92 mm. The quantitative analysis results obtained by the -6 dB altimetric method shall produce large errors of average being 2.94 mm and the standard deviation being 1.37 mm. The measured defect size is generally overvalued with large dispersion, and the quantitative method therefore still needs improvement.
