摘要： A car body for railway rolling stock has a plurality of outside plates (20,21) joined to frame members (12-15) by spot welding. The outside plates are joined to their frame members at least at all their periphery by spot welding. The outside plates are produced of ferrous materials, exclusive of stainless steels. On the outside surface of these outside plates is formed a coating. The outside plates are joined to each other without continuous welding. Because the joining of the outside plates to the frame members and the joining of the outside plates to each other is performed all by spot welding, lessinput heat is required as compared with the continuous welding. Therefore, outside plate distortion can be reduced and it is possible to decrease the time and labour for the manufacture of the car body. As the outside plates are produced of a ferrous material, the painting of the outside surfaces can easily be performed.

摘要翻译： 用于铁路车辆的车身具有通过点焊接合到框架构件（12-15）的多个外板（20,21）。 外板至少在其周边通过点焊而与框架构件接合。 外部板材由不锈钢材料制成。 在这些外板的外表面上形成涂层。 外部板彼此连接而不进行连续焊接。 由于外部板与框架构件的接合和外部板彼此的接合是通过点焊进行的，所以与连续焊接相比，需要较少的输入热。 因此，可以减少外板变形，并且可以减少用于制造车体的时间和劳动。 由于外板由铁类材料制成，所以能够容易地进行外表的涂装。

摘要： The present invention relates to a railwaycar body easy to manufacture at a low material cost. The car body comprises a center underframe (2) produced of light-alloy extruded shapes (4) and an end underframe (3) produced of a ferrous material, and furthermore a roof framing, a side framing and an end framing which constitute the car body (40) composed of outer plate members and frame members produced of a ferrous material. According to the present invention, it is possible to build a railwaycar body easy to manufacture at a low material cost by building the car body of a light-alloy material and a ferrous material.
