摘要:
阐述了螺旋埋弧焊管焊缝中的一种特殊气孔——夹珠型气孔的特征。分析认为,形成该类气孔的主要原因是:在钢管进行内焊之前的成型过程中,由于成型缝间隙不合适而使含有大量铁锈粉末的焊剂夹在了成型缝中,导致钢管内焊过程中产生夹珠型气孔。针对气孔产生的原因,提出了避免该类气孔产生的相应措施。
Abstract:
This article expatiated the character of a special gas pocket,i.e slag in gas pocket.The analysis considered generation causes of this kind of gas pocket was as following:during pipe forming before pipe inside welding,welding flux containing plenty of iron rust powder was sandwiched in forming weld because of improper forming weld gap,so it resulted in slag gas pocket during pipe inside welding.Aiming at generation causes of gas pocket,corresponding precautions were put forward.
