一、问题的提出超声波探伤技术随着工业的发展,应用越来越广泛。近年来,我国超声波应用技术和超声波仪器制造发展很快,仪器制造厂提供了性能较好的仪器和换能器一探头,提高了探伤准确度。但通过探伤实践,深感探头寿命太短,探头的有机玻璃斜块与被探件接 First, the issue of ultrasonic flaw detection technology with the development of industry, more and more widely used. In recent years, China’s application of ultrasonic technology and ultrasonic instrument manufacturing developed rapidly, the instrument manufacturer provides a better performance of the instrument and a transducer probe to improve the detection accuracy. However, through the testing practice, the probe is very short life expectancy, the probe of the plexiglass ramp and the probe is connected
