端点衍射波法测量缺陷自身高度的实验

Experiment of Defects self-height Measurement with Endpoint Diffraction Wave

通过用不同角度和频率的探头,对模拟缺陷自身高度进行测量,并对测量结果进行分析,以了解不同探头及不同高度缺陷对检测结果的影响,掌握端点回波的一些特点。

The paper introduces endpoint diffraction wave method of defects self-height measurement in joint welds by UT. Probes of different angle and frequency were used in the measurement,and comparative analysis of the measured data was made in order to find the influence of different probes and defects of different height on test results and determine some characteristics of endpoint echo as well.
