摘要
在满足检测要求的前提下,选择K值差别较大的横波探头检测时,同一缺陷的反射回波幅值会因探头声束扩散差别较大而有差异。本文通过设计试验来说明这种现象,并研究了K值对缺陷回波幅值的影响。
Under the requirement of detecting, selecting great difference of K value of ultrasonic wave probes to detect, the echo amplitude of the same defect has significant difference because of beam diffusion. The phenomenon test was explained by designing, and the effect of K value on the echo amplitude was studied.
