摘要
本文研究了钢板上缝隙对声发射波传播的影响,当声发射源位于缝隙顶端附近时,缝隙的存在明显影响声发射波的传播,这种缝隙效应能被利用于开发一种新的焊缝跟踪控制方法。
In this paper, the influence of a gap on a plate on propagating acoustic emission waves is investigated. The existence of the gap on the plate remarkably affects the propagation of the acoustic emission waves whose source is near the tip of the gap. This effect of the gap cart be used to develop a tracking control system.
