Ultrasonic Flaw Detection for Quality Assessment of Explosively Clad Plates
Figure 3
The ultrasonic echo responses of the point defect (a) 1 amplitude, 2 A scan (static envelope), 3 range, 4 variation of peak signal amplitude (dynamic envelope), 5 probe position, and 6 reflector; beam axis tip location technique (b) 1 and 3 echoes and at maximum heights, 2 variation of peak signal amplitude, 4 A scan and 5 echoes and will be the first to appear when probe is moved backward and forward; the dimensions of substitute crack (c).
