Abstract
Method of manufacturing a metal structural component (E) for a vehicle, comprising the steps of a) providing a planar blank (B); b) cutting out the blank (B) to create an opening (A) having a first portion (Q) and wherein the first portion (Q) of the opening A) has a second length (lt) in a first transverse direction (T); c) welding a patch (P) to the blank (B) so as to cover the opening (A), the patch (P) being made of the metal having greater ductility than the material of the blank (B); d) stamping the assembly formed by the blank (B) and the patch (P) to obtain the component (E).
