如何防止螺旋焊缝汇管多开孔后的焊接变形

The Method to Prevent the Welding Deformation of Spiral-seam Pipe Hea der after Tapping

    摘要
  • 摘要: 介绍了在螺旋焊缝汇管上焊接支管时的防变形措施、焊接方法和检验结果。采用灵活的方法, 合理确定开孔位置, 尽量避免将开口开在焊缝上, 同时采用对称焊和间断焊法施焊, 可以减小钢管挠曲变形, 提高焊接质量。

     

    Abstract: This paper introduces the measure, welding method and inspection result to preve nt the welding deformation formation of spiral-seam pipe header after tapping. The author considers that to prevent the deformation and ensure the welding quality, to rationally determine the tapping location and avoid the holes upon the spiral seam is important.
