本文主要对天然气场站工程管线焊接缺陷——气孔产生的原因进行了分析,对焊缝气孔的预防措施分别从消除气体来源、控制焊接工艺方面进行了阐述,为今后天然气场站工程工艺管线预防焊接缺陷——气孔提供技术参考。
This paper mainly analyzes the causes of gas hole defects in natural gas station engineering pipelines. The prevention measures of gas hole in gas field are respectively elaborated from the aspects of eliminating gas source and controlling the welding process. In the future, Welding defects - pores provide a technical reference.
