Abstract
PURPOSE: To obtain quickly the accurate information as well as to secure a big reduction of the load for the workers by adding the pseudo signal generator which is excited by the contents of two memory units memorizing the maximum reflected wave height and the maximum wave position each.
CONSTITUTION: The pulse sent from transmission part 1 is converted into the ultrasonic pulse via probe 2 and then thrown into material 3 to be tested. The reflected wave from defect F of welded part 4 is converted into the pulse via probe 2 and then supplied to CRT6 after amplification 5. In this case, the output of amplifier 5 is sent to memory unit 8 along with selection of only the reflected wave obtained between the markers which are set previously at gate part 7 and can be erased with the optional change secured for their positions. And the maximum value is always memorized among the variations of the height of the reflected waves obtained during the scan of probe 2. By the output of the memorized maximum value, the reflected wave position showing the maximum value is memorized in memory unit 9. And pseudo signal generator 10 is excited based on the contents of both memory units 8 and 9 to supply the pseudo signals to CRT6 via switch S.
