Abstract

A car body for railway rolling stock wherein a plurality of outside plates forming the car body are joined to frame members of the car body by spot welding. The outside plates are produced of a ferrous material except for stainless steel and a film or coating is provided on an outside surface of the outside plates. By virtue of the joining of the outside plates to the frame members and the joining of the outside plates to each other by spot welding, less input heat is required as compared with a continuous welding; therefore, outside plate distortion can be reduced and time and labor for manufacturing of the car body can be reduced. Moreover, since the outside plates are produced of a ferrous material, the painting of the outside surfaces of the outside plates can easily be accomplished.
