- 摘要:
- 海洋平台构件中的导管、撑管,因管径小,其环焊缝只能采用单面焊双面成型焊接工艺。为此,用D32钢进行了焊接工艺试验,研究了装配尺寸、运条方式、引弧、熄弧和连弧技术对焊接质量的影响,总结出了获得满意反面成型焊缝的装配尺寸和焊接工艺参数。该方法已成功应用于钻井平台、采油平台、防冰隔水套管等工程的焊接施工中,均取得了良好的效果。
Owing to the small diameters of conduit pipes and bracing tubes, the girth welding has to be done with one side welding both sides formation technology. Therefore the welding technology testing is carried out using D32 steel. The assembly dimensions of reverse side formation welding seams and parameters of welding technology are obtained satisfactorily. This technique has been used successfully to the welding constructions of drilling platform, production platform, ice-resistance and water-proof casing pipe etc., and the good results have been gained.2004,3(3): 25-34,4 收稿日期：2003-12-9分类号：TE973.3基金项目：胜利油田科学研究与技术开发项目编号:YJ-03-03作者简介：刘晓旭(1970-),女,吉林松原人,1993年毕业于石油大学机械系焊接设备及工艺专业,工程师,多年来一直从事石油化工及焊接工艺方面的施工技术管理工作.通讯地址:山东省东营市西四路446号.参考文献：
