The Influence of the Placement and Characterization of Defects on Echo Amplitude in Ultrasonic Testing

The response amplitude shall be influenced by the location, shape, size and angle of defects in ultrasonic testing. This paper prepared several different type workpiece in which artificial defects were embedded. We measured the response amplitude of artificial defects and analyzed the influence for ultrasonic response amplitude by the location and types of defects. This paper might have guidance significance for ultrasonic testing.
