管道焊接施工技术管理要点

通过对输油站在管道灶接工中经常出现的焊接质量问题的分析，指出了管道焊接施工技术现场管理的重要性，尤其是在输油站的安装中，所用管子，管件，阀门等因接口尺寸偏差，母材不同，壁厚不等诸因素，易影响焊接质量，更应重视焊接施展 技术管理，焊接施工技术管理要点主要有：严格遵守焊接施工规范，焊接材料管理，焊工的管理，坡口形式，焊接作业环境，焊缝质量检验等工作，对注意事项均作了简要说明。

Key point in technical management of pipeline welding construction

By analyzing problems of welding quality often occurred in pipeline welding construction at oil transport station, points out the significance of on-site technical management in pipeline welding construction. More attention shall be paid to technical management in welding construction, especially in installation of oil transport station, in which many factors such as joint size deviation of pipes, fittings and valves adopt- ed, different mother material and wall thickness will affect welding quality. The key points of technical management in welding construction: strictly abide by welding construction specification, welding material management, welder management, bevel shape, welding procedure environment, joint quality inspection. Meanwhile gives a brief introduction about precautions.
