简要介绍利用与工件同材质的简单条形试块,对横波斜探头K值的确定及扫描速度的调节原理、方法,并用30C rM nS i及LY 12两种不同的试块进行了实际操作,分析了可能出现误差的原因。
This paper briefly introduces the principle and method of determining the K value of the shear wave probe and the scanning speed by using a simple strip test block of the same material with the workpiece. The practical operation is carried out with two different test blocks: 30C rM nS i and LY 12. Analysis of the possible causes of error.
