摘要
Abstract
The advantage of ultrasonic testing is the high detectable rate for planar flaw. When the axis of the reference sound beam is not normal to the flaw,the reflected wave will be difficult to be received by the probe due to the influence of the directivity of planar flaw and the flaw can not be detected. The influence of the directivity of planar flaw on the reliability of vertical contact technique is analyzed. Test samples with different size and directional flaws are made,and contrast tests are made. Then the correspong-ding measures are proposed.关键词
