Analysis for Abnormal Wave of Bolt Detected By Ultrasonic Longitudinal Wave Detection

摘要：

　　When the bolt was detected by ultrasonic longitudinal wave detection,abnormal wave appeared,the feature of the wave was: high energy,instability,regularity and had no effect on thread reflected wave.After studied on the abnormal wave,we were sure that,the wave was not defect wave,but nut cap reflected wave because of excessive of couplant.
