摘要
根据 X光射线的投影原理及双面螺旋埋弧焊钢管双丝焊焊缝的内部形状 ,分析了用 X光显像判别双丝焊内外焊偏移量存在的问题 ,提出了应注意的三种情况 。
According to the projecting theory of x-ray and double wire weld seam inside structure of both side spiral merged-arc welded pipe,it analyzes the problem of judging double wire weld seam bias,also raises three concerning situation.These have the reference role for accurate judging bias.
