海上接桩自动焊接工艺

Development of Automatic Welding Applying to Offshore Steel Pile Connection

针对海上接桩施工的特点及其面临的诸多实际问题，利用已开发的海上接桩自动焊系统对海上接桩横焊工艺进行了实验研究。主娶包括海上接楗焊接王艺方法逸择，海上接桩横焊工艺试验验证．

The construction cost of jacket installation is very expensive because of its high risk, tensional construction period, the threat of bad weather, high quality requirement, etc. As a most important procedure, the welding quality and efficiency of offshore steel pile connection decide the construction period to great extant. Based on the mentioned characteristics and the preliminary analysis of practical problems, this paper studies the horizontal welding process of offshore steel pile connection with the developed automatic welding system, including the selection of welding method and identification by experiments.
