13、涨踏焦强假沧甲嫂僳近代造船技术的发展过程是由手工操作向机械化、自动化迈进的过程。自50年代起，船体建造用焊接取代了铆接，使船体建造由过去长期使用的零星散装方式改进为分段装配方式，大大提高了造船效率。焊接方法从全手工焊接发展为埋弧自动焊(见埋弧焊)、半自动焊、电渣焊、气体保护电弧焊。自60年代中期起，又有单面焊双面成形、重力焊、自动角焊以及垂直焊和横向自动焊等新技术。焊接设备和焊接材料也有相应发展。由于船体结构比较复杂，在难以施行自动焊和半自动焊的位置仍需要采用手工焊。结合焊接技术的发展,自60年代起,在船体部件和分段装配中开始分别采用 T型材装焊流水线和平面分段装焊流水线。T 型材是构成平面分
14、段骨架的基本构件。平面分段在船体结构中占有相当的比重，例如在大型散装货船和油船上，平面分段可占船体总重的50以上。平面分段装焊流水线包括各种专用装配焊接设备，它利用输送装置连续进行进料、拼板焊接以及装焊骨架等作业，能显著地提高分段装配的机械化程度，成为现代造船厂技术改造的主要内容之一。船舶构件安装和焊接工艺设论文6.2.6 establishing construction site welding secondary, secondary electrode consisted of Rod piled up, welding rod ovens, incubators, thermomet
