| Abstract: | The flaw determination and evalution methods of ultrasonic automatic flaw detection examining on welded steel pipes are introduced. With the careful programming of time correlation, location correlation, behavior correlation, features correlation, and nature correlation together with related software program, the testing system thus has a smart judgment function to evaluate correctly and select strictly for complex flaw echo, and its error in alarm can be effectively avoided. So designed system was able to meet the continuous automation testing requirements and achieve misinformation rate smaller 2% and fail to report rate to 0. |
