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.

    本发明公开一种钣金总成、钣金焊接方法和车辆。该钣金总成,包括至少两个钣金件和激光焊接结构;至少两个所述钣金件沿竖直方向堆叠设置,相邻两个所述钣金件之间的钣金间隙小于第一阈值,所述第一阈值为最上层钣金件的厚度与第一系数的乘积,所述第一系数的取值范围为[0.2,0.4];所述激光焊接结构包括第一焊接结构和/或第二焊接结构,所述第一焊接结构为沿竖直方向未贯穿最下层钣金件的焊接结构,所述第二焊接结构为沿竖直方向贯穿最下层钣金件的焊接结构。该钣金总成在生产过程中,保障其钣金间隙符合激光焊接需求,采用激光焊接技术进行焊接,有助于保障其效率和成品质量。
