螺旋焊管X射线工业电视检测系统研究

摘要

In order to obtain higher precision in X-ray detection of spiral welded pipe weld, thus to meet the requirements of production, the defect specimen pipe was made according to standard, and the X-ray industrial TV detecting system of weld defect was tested. The results indicated that the weld detection speed can up to 6 m/min;welded pipe with 8.8 mm thickness, the minimum defect diameter is 0.6 mm, the minimum width of stripy defect is 1 mm, and the depth is 1 mm; welded pipe with 15.9 mm thickness, the minimum defect diameter is 1 mm, the minimum width of stripy defect is 1 mm, and the depth is 1 mm. Test results showed that the detection system got better results in the production line commissioning.%为了在螺旋焊管焊缝X射线检测时获得较高的精度，满足生产需要，根据标准制作了缺陷样管，对焊缝X射线工业电视检测系统进行了测试。结果显示，焊缝检测速度可达6 m/min；厚度8.8 mm焊管检出的最小圆形缺陷直径为0.6 mm，检出最小条形缺陷宽度1 mm，深度1 mm；厚度15.9 mm焊管检出的最小圆形缺陷直径1 mm，检出的最小条形缺陷宽度1 mm，深度1 mm。测试结果表明，该检测系统在生产线上试运行时取得了较好的效果。
