焊接作为船舶建造中非常重要的一个环节，面对焊接质量要求越来越高，而优秀电焊人才难求的局面，发展机械化、自动化焊接技术，在目前尤为必要。焊剂石棉衬垫单面焊（FAB法），作为一种高效的焊接方法，比FCB更灵活、适应分段更广。特别是扩大了曲面分段的焊接自动化，在一定程度上提高了船厂企业的生产效率。%s:Welding is a very important part in shipbuilding. Facing the higher and higher quality for the welding quality demand with the shortage of excellent welder, it is particularly necessary to develop the welding technology of mechanization and automation at present. The flux asbestos backing welding technology by one side (FAB), as an efficient welding method, is more flexible than FCB, and has wider adaptive segmentation. Especially the expanded surface section welding automation improves, to a certain extent, the production efficiency of ship enterprises.
