全焊结构的铁路机车车辆的车体以单壳设计为基础，采用了计算机辅助设计和有限元分析方法。结构设计的刚性强度大约是普通设计的10倍，而重量却比普通机车结构轻约25％。机车的结构金属材料选用ASTMA588耐候销和304L不锈钢。根据不同类型的金属和厚度，采用9种不同的焊接方法和工艺将成形金属构件组装成车体结构。大多数零部件均以某种方式焊接到车体上。介绍了机车车体的焊接工艺和设备及车体的基本构造，还介绍了长岛铁路公司购买的新型客车在日本的焊接生产情况。新型客车车体采用301L不锈钢作为其结构材料，其主要的焊接工艺是电阻点焊。底架和其他构件均为A588碳素钢，采用MIG和TIG焊。采用AWSD15．1标准作为焊接制造标准。
All-welded structure of the railway rolling stock body to single-shell design based on the use of computer-aided design and finite element analysis. The rigidity of the structural design is about 10 times that of the ordinary design, but the weight is about 25% lighter than that of the ordinary locomotive. The structure of the locomotive material selection ASTMA588 weathering pins and 304L stainless steel. Depending on the type of metal and its thickness, 9 different weld methods and processes are used to assemble the formed metal components into a body structure. Most parts are somehow welded to the bodywork. The welding process, equipment and basic structure of locomotive body are introduced. The welding production situation of new bus purchased by Long Island Railway Company in Japan is also introduced. The new bus body 301L stainless steel as its structural materials, the main welding process is resistance spot welding. The chassis and other components are A588 carbon steel, using MIG and TIG welding. Adopt AWSD15.1 standard as welding manufacturing standard.
