摘要
通过开展陆地长输管道自动焊AUT技术的可靠性评价研究工作,建立了一套完整的AUT广义可靠性理论及评价体系。通过缺陷样本容量的建立与优化计算,开展AUT工艺评定及可靠性分析工作,结合AUT、RT、切片的检测结果,定量论证了AUT技术在全自动焊接质量验收环节方面的可靠性及先进性,为国内陆地长输管道的自动焊+自动超声检测一体化施工提供技术支撑。
A set of general reliability theory and evaluation system for automatic ultrasonic testing(AUT) is founded through the research on ultrasonic testing reliability evaluation for land long- distance pipeline with automatic welding joints.By means of establishment and optimization calculation of defect sample size,AUT process evaluation and reliability analysis,as well as testing results from AUT,RT and slices,the reliability and advancement of AUT technology in automatic welding quality inspection are quantitatively verified,which will provide technical support for domestic land long- distance pipelines in automatic welding + AUT integral construction.
