为了有效地检出缺陷和得到正确的、重复性的测定结果,试件超声波探伤时,不仅需要应用性能良好的仪器设备和适当的探伤方法,而且还需要必要的探测条件来保证。那么,探测条件包括那些主要内容呢?怎样选定才能达到合适的要求?对此,我们按照超声波探伤的一般程序,分别讲述如下。试件的制备 In order to detect the defects effectively and obtain the correct and repetitive results, the ultrasonic flaw detection of the specimen not only requires the application of good equipment and proper testing methods, but also requires the necessary detection conditions to ensure. Well, the detection conditions include those main content? How to choose to meet the appropriate requirements? In this regard, we follow the general procedure of ultrasonic flaw detection, respectively, as follows. Preparation of test pieces
