Abstract

A method of producing a stabilizer (10) of a motor vehicle, such that the stabilizer includes a torsion bar (11) and longitudinal links (12, 13). The longitudinal links (12, 13) are in each case connected to the torsion bar (11) by welding, and the longitudinal links (12, 13) and the torsion bar (11) are heat-treated before welding. Each longitudinal link (12, 13) is welded at one end to the torsion bar (11) on both sides, in each case, by a respective multilayer weld seam (14), and each weld seam (14) is made with unequal widths such that the width of the weld seam (14) adjacent to the torsion bar (11) is shorter than its width adjacent to the respective longitudinal link (12, 13).
