- 摘要:
- 报道大庆和武汉两家公司研制的大口径输油管道超声波探伤仪及其自动检测技术原理和方法.该设备与工业控制计算机联合使用,利用多通道超声波探伤仪将六探头排列在焊缝两侧,由回转机构带动探头检测管道对接焊缝,发现缺陷即报警并标识,从而实现了探伤作业自动化.
In application of the multi-channel ultrasonic detector,six probes are arranged on both sides of the weld and rotated around the weld by a m-otion mechanism located outside the pipeline,when a defect in the weld is scanned,the detector will give an alarm and make a mark.By this way the automatic detection of weld is realized.2001,1(1): 25-28 收稿日期：2000-8-31分类号：TG441.7
