场站管道焊接缺陷原因及防范措施研究

Research on Causes and preventive measures of station pipeline welding defects

天然气场站属于石油天然气企业的重要组成部分,管道焊接质量及焊接工艺均属于场站管道焊接的关键内容,焊接缺陷主要包括焊接裂缝、未填满、烧穿、咬边、未熔合、气孔、夹渣及未焊透、不致密、不连续等。由于焊接缺陷的存在,极大程度对场站管道应用的安全性产生不利影响,为更好的满足焊接需求,必须合理进行焊接缺陷的把控,以促进焊接质量的提升。

Natural gas station is an important part of oil and gas enterprises,pipeline welding quality and welding process are the key content of station pipeline welding,welding defects mainly include welding cracks,unfilled,burn through,undercut,lack of fusion,pores,slag and incomplete penetration,not dense,discontinuous and so on.Due to the existence of welding defects,it has a great adverse impact on the safety of station pipeline application.In order to better meet the welding demand,it is necessary to control the welding defects reasonably,so as to promote the improvement of welding quality.
