摘要

通过调整超声波检测参数

研究分析ZG0Cr13Ni4Mo铸钢件检测反射回波波幅与超声波检测参数变化的关系。试验结果表明

探头频率、直径对对回波增益产生较大影响

当铸钢件壁厚<75 mm时

宜选用频率为2.5 MHz;当壁厚≥75 mm时

宜选择频率为2.25 MHz

探头晶片直径为20 mm较佳。

Abstract

The paper studies and analyses the change relationship between the echo waveforms amplitude and various ultrasonic testing parameters of ZG0Cr13Ni4Mo casting steel testing by adjusting ultrasonic testing parameters.Experiment results show that the variations of frequency or diameter of ultrasonic transducer have great impact on echo waveform amplification.Frequency of 2.5MHz is suitable for ultrasonic testing when wall thickness is less than 75mm

and frequency of 2.25MHz is suitable when wall thickness is more than 75mm.Diameter of probe wafer is 20mm better.
