Title: A method of determining a fault expectancy zone for ultrasonic testing
IPC: G01N29/04
Filed: 1981-03-27
Abstract: In the ultrasonic testing of a pipe, for example, in order to exclude the pulse 5 and echoes 6 and 7' from consideration and concentrate evaluation on echo 7, a fault expectancy zone 10 is established. The method employed involves calculating the start time and duration of an approximate expectancy zone, subdividing said approximate zone into a plurality of shorter time intervals and, in each of a plurality of cycles of operation, transmitting an ultrasonic pulse into a test piece and recording the echo amplitude occurring during a respective one of such intervals, and thereafter locating the mid-point of the fault expectancy zone to be determined within the time interval wherein was recorded the maximum echo amplitude. <IMAGE>
