The light-alloy hybrid wheel manufacture method implementing the following separate operation phases: creating a flange (2), having an inner profile (2a) capable of making up a tire bead seat; creating a rim (1) having, on one side, an outer profile (1a) capable of forming a tire bead seat and, on the other side, a circular flank (1b) intended to be assembled with part (2b) of the flange (2); and assembling the flange (2) with the rim (1), at the seat (2a) of said flange (2) and at the circular flank (1b) of the rim (1). Said method is characterized in that assembly of the rim (1) with the flange (2) is carried out by welding the circular flank (1b) of the rim and the flange (2) using a single friction stir weld (5) using a slug in a position enabling access on both sides of the weld. 轻合金混合车轮的制造方法实施以下各个操作阶段：-实现具有内轮廓(2a)的轮盘(2)，该内轮廓能够构成轮胎跟部的底座部；-实现轮毂(1)，所述轮毂在侧具有能够构成轮胎跟部的底座部的外轮廓(1a)且在另侧具有与所述轮盘(2)的部分(2b)组装的圆形侧部(1b)；-在轮盘(2)的底座部(2a)以及轮毂(1)的圆形侧部(1b)处组装所述轮盘(2)和所述轮毂(1)；其特征在于，所述轮毂(1)和所述轮盘(2)之间的组装通过所述轮毂(1)的所述圆形侧部(1b)和所述
