铁素体钢薄板对接焊缝相控阵超声检测标准分析

Analysis of Phased Array Ultrasonic Testing Standard for Ferrite steel Thin-Plate Butt Welds of Nuclear Power Plant

为推动相控阵超声检测技术在核电厂铁素体钢薄板对接焊缝上的工程应用,对国、内外适用于铁素体钢薄板对接焊缝相控阵超声检测技术标准的主要内容进行了分析,ISO 13588—2019、DL/T 1718—2017和NB/T 47013.15—2021比较适合作为核电厂薄板对接焊缝相控阵超声检测的参考标准,核电厂铁素体钢薄板对接焊缝相控阵超声检测应用可参考NB/T 47013.3—2015检测灵敏度和验收标准要求。该结论可为核电厂铁素体钢薄板对接焊缝相控阵超声检测技术的工程应用提供参考。

In order to promote the engineering application of PAUT technology in ferrite steel thin-plate butt welds of nuclear power plant,this paper compared and analyzed the major requirements of the domestic and foreign common PAUT standards which are applicable to ferrite steel thin-plate butt welds,ISO 13588—2019,DL/T 1718—2017,and NB/T 47013.15—2021 are more suitable as reference standards for phased array ultrasonic testing of thin-plate butt welds in nuclear power plants.The application of phased array ultrasonic testing of ferritic steel thin-plate butt welds in nuclear power plants can refer to the requirements of NB/T 47013.3—2015 for testing sensitivity and acceptance standards.This conclusion can provide reference for the engineering application of phased array ultrasonic testing technology for ferrite steel thin-plate butt welds of nuclear plant.
