介绍了超声波测量裂纹类缺陷自身高度的不同方法及各种方法的优缺点。重点讨论了端点反射波 法测量裂纹自身高度的计算方法,对非裂纹类缺陷自身高度进行测量也可参照本方法进行。
The different methods of ultrasonic measuring the height of crack defects and the advantages and disadvantages of various methods are introduced. The calculation method of endpoint reflection wave method to measure the height of crack itself is mainly discussed. For the measurement of the height of non-crack defects, the method can also refer to this method.
