螺旋埋弧焊管焊缝两侧圆度的分析

Roundness Analysis in Both Sides of Weld Seam in Spirally Submerged Arc Welded Pipe

主要分析了成型机之前的工序及扩径机对螺旋缝埋弧焊管焊缝两侧圆度的影响 ,提出了要提高钢管焊缝两侧的圆度 ,必须从拆卷开始进行生产工艺全过程的控制。

It mainly analyzes all process before forming and enlarging diameter machine,which affect the weld seam sides roundness in spiral submerged arc welded pipe,points out that the full process control from uncoiling can improve the seam sides roundness.It can effectively solve the problem of weld seam sides roundness in spiral submerged arc welded pipe.
