超声波探伤中探头K值的选择

摘要

In this paper use horizontal hole and vertical hole as reference reflecting hole. Choosing variousK value angle probe doing examination.Get hole of K value of angle probe and test block reference reflecting hole must be suitable.%本文选用不同K值探头以横孔和柱孔为参考反射孔进行探伤实验，得到两条重要的规律：横孔与柱孔在同声程、相同K值下反射脉冲值是变化的；不同的K值探头对同声程、相同的参考反射孔之反射脉冲值也是变化的
