The invention discloses a metal plate assembly, a metal plate welding method and a vehicle. The sheet metal assembly comprises at least two sheet metal parts and a laser welding structure. The at least two sheet metal parts are stacked in the vertical direction, the sheet metal gap between every two adjacent sheet metal parts is smaller than a first threshold value, the first threshold value is the product of the thickness of the sheet metal part on the uppermost layer and a first coefficient, and the value range of the first coefficient is [0.2, 0.4]; the laser welding structure comprises a first welding structure and/or a second welding structure, the first welding structure is a welding structure which does not penetrate through the lowermost sheet metal part in the vertical direction, and the second welding structure is a welding structure which penetrates through the lowermost sheet metal part in the vertical direction. In the production process of the metal plate assembly, it is guaranteed that the metal plate gap meets the laser welding requirement, the laser welding technology is adopted for welding, and it is helpful to guarantee the efficiency and the finished product quality.
