In ultrasonic testing of workpieces such as stainless steel and carbon steel pipeline steel,corresponding to different problems existing in the workpieces,the bottom wave will appear as the disappearance or decrease of the bottom wave.The aim is to combine the changes in bottom waves encountered in actual testing,study the corresponding relationship between the problems and changes in bottom waves of workpieces such as stainless steel and carbon steel pipeline steel under different conditions,and provide reference for ultrasonic testing of various products.
