超声波探伤能够在不退车轮的情况下,对车轴的轮座部分施行检查,并能比较准确地鉴定其内部的隐蔽缺陷,对保证防止断轴,确保行车安全有着重要的作用。但是,由于超声波探伤时会出现许多假象反射,在很大的程度上阻碍了超声波探伤的广泛应用。为了使超声波探伤技术在铁路部门的应用日益完善,本文对超声波探伤的假象反射进行了分析和探讨。车轴轮座部位的超声波探伤与其他工件探伤的不同点在于:轮座与轮孔接触面间经长期运用后,会产生一定程度的摩擦腐蚀、透油、透锈、夹杂杂质等情况,这些夹杂物都会在荧光屏上造成不同强度的友射波,这些反射波称
Ultrasonic flaw detection in the case of no wheel, the wheel seat parts of the implementation of inspection and can more accurately identify its internal hidden defects, to ensure prevention of broken shaft, to ensure traffic safety has an important role. However, due to the appearance of many false reflections during ultrasonic inspection, the widespread application of ultrasonic flaw detection is hindered to a large extent. In order to improve the application of ultrasonic flaw detection technology in the railway sector, this paper analyzes and discusses the illusion reflections of ultrasonic flaw detection. Ultrasonic testing of wheel axle seat parts and other parts of the difference is that: the contact surface between the wheel seat and wheel hole after long-term use, there will be a certain degree of friction corrosion, oil, rust, inclusions and other impurities, these inclusions Things will be caused by friends of different intensities on the screen, these reflected waves said
