Method and Device for verification by Ultra Sound of pins with a Jump of Wall Thickness

摘要

Method and Device for Ultrasonic Testing of pins with a Jump In Wall thickness with respect to cracks that share the same.It includes the following Operations: First, the transmitter and receiver for Ultrasonic Waves, were applied on the thicker side of the pin, on its Periphery, so that the jump of Wall thickness is in the area of Near Field; Second, with the issuer D Waves RADIATE To jump and Ultrasonic Wall thickness; and finally,The intensity of the reflected waves are compared with an echo characteristic Curve was obtained with a Probe corresponding to the Pin to verify that Simulate cracks, grooves of varying depth.
