铁路货车交叉杆端头对接焊缝超声波探伤技术

摘要

According to the structure characteristics of butt-jointed seam of the railway wagon cross brace end socket,the paper introduces how to choice a target-oriented detector,a test block with a proper sensitivity,a proper probe type and so forth in ultrasonic detection applied to a butt-jointed seam. It also puts forward measures ensuring detection accuracy in view of main detect types during detection.%根据铁路货车交叉杆端头对接焊缝的结构特点，介绍在对接焊缝超声波探伤过程中，如何选择有针对性的探伤仪器、恰当的灵敏度试块、适用的探头型号等。分析检测过程中出现的主要缺陷类型，提出为保证探伤检测准确性而采取的措施。
