螺旋缝埋弧焊管焊缝气孔产生原因综合分析及防止措施

Porosity Causes Comprehensive Analysis and Preventive Measure of SSAW Pipe

针对各种影响因素提出了预防减少焊缝中气孔的具体措施:①规范焊剂和焊丝的管理和使用;②对钢板表面和边板采取处理措施;③合理调整焊接工艺参数。

This article analyzed and introduced gas pocket generating causes of SSAW pipe, and put forward preventive measures ： 1） to standardize management and usage of welding wire and flux ;2） to take measures to dispose steel plate surface and edges;3） to reasonably adjust welding process parameter.
