Abstract
The initialization and preparation procedure described involves particularly ultrasonic test equipment for ultrasonic inspection of welding seams of pipes while passing through a production line. A dummy is used off line to determine suitable distances and orientation of test heads and to acquire relevant transit time and amplitude data. A standard is then used to obtain additional reference data to be related to the dummy test data. After the test heads are installed in the production line test stand, tests are repeated with the standard to obtain now the needed test reference data in conjunction with the previously related data. This way, looking windows for flaw echos as well as sensitivity data for the subsequent tests are accurately and reproducibly predetermined.
