超声波探伤探头工作频率的新测法

A new measurement method for working frequency of probein ultrasonic flaw detection

通过理论分析与测试,提出厂一种测试探头工作频率的新方法.实践表明,这种方法具有简便、快速、涉及的参数少、易于掌握等特点,对于探头定位误差的修正很有意义,可以进一步提高焊缝超声波探伤的准确性.

Through theoretical analysis and test,a new method to measure the working frequency of probe is proposed.Practice shows that the method is simple,raid,easy to grasp,and relates to few parameters.It has some important meaning to the modification of the probe location error,and can further improve the accuracy of ultrasonic test for the weld joint.
