摘　　要：水下管道的焊接由于受水下环境的影响,焊接方法与焊接设备都较陆地上的复杂得多,它具有可见度差、焊缝含氢量高、冷却速度快、电弧电压高和连续作业困难等特点。综述了水下管道焊接技术研究与应用的最新进展,并就水下焊接技术的发展趋势提出了看法。Being affected by the water circumstance,the ways and equipments of pipeline welding are more difficult and complex under water than on land.The process of welding has less visibility,faster cooling velocity,higher hydrogenous rate,higher welding voltage and continuous welding task and so on.So the paper summarizes the latest technological progress of pipeline underwater welding and points out its development tendency in the future.
