| 摘 要： | 根据ＡＰＩ标准的要求，对油气输送用螺旋埋弧焊缝缺陷补焊必须使用低氢型焊条。在苏丹管线用螺旋埋弧焊管生产过程，根据钢级及强度匹配要求，选用Ｊ５５７焊条作为打底焊材料。经过多次试验，总结一种补焊工艺，采用该工艺解决了低氢型焊条打底焊时因溶池温度过高难以控制的问题，防止了根据焊道气孔的产生，并满足了技术要求。

| Abstract: | Low--Hydrogen electrode must be used in the repair welding of
SSAW pipe line's weld defects for oil and gas transmission in accordance with the
requirement of API Spec.5L. During the manufacturing of SSAW pipe for Sudan pipeline,
J557 electrode shall be applied as bottom weld materials according to the matched
requirement of grade and strength. Through many tests, a repair welding procedure is
established. The adoption of this procedure solves the temperature problem which is
hard to control in fusion pool, prevents the gas pocket which is produced in the bottom
weld pass and meets the technical requirement. |
