摘要
为改变海洋平台导管架海上安装桩管焊接工作量大、效率低的现状,开展了自动焊工艺技术的试验研究。文章从焊接方法的选择、焊接工艺试验、工程应用等方面论述了针对桩管常用的D32和E36高强船用钢,采用自保护药芯焊丝进行自动焊的研究内容。试验结果及现场应用表明:该方法效率高,抗风能力强,接头性能完全满足工艺规范的要求。
In order to improve the status of great welding workload and poor efficiency in offshore installation of offshore platform pile pipes,the test research of automatic welding technology was performed.This paper introduces the test research contents of automatic welding technology using self-shielded flux-cored electrode(SSFCE) for high tensile D32 and E36 shipbuilding steels widely used for pile pipes.The test results and field application prove that this method has advantages of high efficiency and strong wind resistance,and the welding joint properties meet the demands of the welding criterion.This automatic welding machine is worthy of popularizing application.
