焊接钢管超声波自动探伤检测系统的软件设计与应用

摘要

In this article, the software design and application current status of automatic ultrasonic inspection system for welded pipe were analyzed. Combined traditional ultrasonic non-destructive inspection technology with some advanced technologies, such as industrial control computer, virtual instrument, intelligent flaw detection and so on, through flaw detection operational procedure, the complex flaw echo can be evaluated accurately and selected strictly. This will effectively avoid error alarm; the flaw waveform playback can overcome insufficiency of identifying flaw type. The field service proved that the false alarm rate is lower 2%, and the missing report rate is 0.%分析了焊接钢管超声波自动探伤检测系统的软件设计以及在焊接钢管检测中的应用状况.该系统把传统的超声波无损检测技术和先进的工业控制计算机、虚拟仪器、智能化探伤等技术相结合,通过探伤操作程序,可实现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,而且其缺陷波形回放克服了超声波自动探伤检测中的缺陷种类难以识别的不足.现场使用证明该系统误报率小于2％,漏报率为0.
