摘　　要：分析了焊接钢管超声波自动探伤检测中的缺陷相关评判方法,配合编制的时间相关、位置相关、行为相关、特征相关、性质相关的5种相关法判伤软件程序,使自动化探伤系统具有了智能评判功能,可做到对复杂缺陷回波的准确评价和严格筛选,有效地避免了系统的误报警,可满足连续自动化探伤要求,并做到误报率<2%,漏报率为0。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.
