提高小径管焊缝椭圆成像有效检出范围的途径

An Approach to Effective Checking Range of Elliptic Imaging on Small Diameter Tube Weld Seam

小径管焊缝在 X射线一次椭圆透照中 ,由于壁厚变化较大 ,检出范围较小 ,该文提出了一些技术措施 。

A small diameter tube weld seam is inspected with X ray elliptic imaging, finding that inspection range is enlarged due to the variation of its wall thickness
