The embodiment of the invention provides a side wall manufacturing method, a side wall, a carriage and a rail vehicle. The side wall manufacturing method comprises the steps that a plurality of sub-skins and a plurality of corresponding sub-frameworks are subjected to laser welding to obtain a plurality of side wall modules; and the multiple side wall modules are subjected to laser welding to obtain the side wall. According to the embodiment of the side wall manufacturing method, the side wall, the carriage and the rail vehicle, the side wall is divided into the multiple side wall modules, each side wall module comprises the sub-skins and the sub-frameworks, the side wall is formed by assembling the multiple side wall modules, so that the size of a single sub-skin is reduced, the planeness of the skins is favorably controlled, and the planeness error of the assembled skins is reduced.
本申请实施例中提供了一种侧墙制造方法、侧墙、车厢及轨道车辆,侧墙制造方法包括:将多个子蒙皮与对应的多个子骨架激光焊接得到多个侧墙模块;将多个侧墙模块激光焊接得到侧墙。本申请实施例通过将侧墙分为多个侧墙模块,侧墙模块包括子蒙皮和子骨架,侧墙由多个侧墙模块组装而成,从而降低了单个子蒙皮的尺寸,有利于控制蒙皮的平面度,降低组装后蒙皮的平面度误差。
