筒体纵缝缺陷定位修正程序与应用

The correction procedure and application of defect for longitudinal weld

筒体纵缝实施超声波检测时,缺陷的位置不能直接从仪器设备得到,而需要修正,本文以VF开发了缺陷定位修正程序并应用于现场,辅助探伤检测人员对缺陷位置进行估算。

When the longitudinal weld of the cylinder is tested by ultrasonic, the position of the defect cannot be directly obtained from the instrument and needs to be corrected. In this paper, the defect positioning correction program is developed by VF and applied to the site to assist the flaw detection personnel to estimate the defect position.
