插入式接管角焊缝超声波检测的缺陷自动定位系统

Auto Defect Location of Inserted Type Nozzle Joints

摘要: 插入式接管的管座角焊缝超声波检测时, 探头应尽量保持与焊缝垂直, 随着检测过程中探伤面的曲率不断变化, 若按常规的缺陷定位方法容易产生错判, 造成不必要的返修。通过建立数学模型推导出插入式接管管座角焊缝缺陷定位的公式, 并利用Matlab建立了缺陷自动定位系统。降低了定位误判造成错误返修的可能性, 并为缺陷返修提供了依据。

Abstract: While carrying on ultrasonic testing, the probe should be perpendicular to welding and the radio of urvature of testing surface is changing. According to the conventional method, the operator is easy to make fault judgment. This article establishes a mathematical model of defect location and an auto defection location with matlab. The above-mentioned an veduce the possibility of repairing work caused by misjudgment and provide ground for repairing thg fault component.
