The three-dimensional configuration has a non-uniform open transversal section along the body. The method includes joining several metal sheet elements together by welding in order to produce a flat tailored blank and shaping the tailored blank to produce the body. Shaping is carried out by hot or cold stamping. The several metal sheet elements can be joined either mutually adjacent or overlaid by different welding techniques, they can be of different of identical thicknesses and of the same type or different types of steel.

摘要： Methods for joining a first blank and a second blank, wherein the first blank and the second blank include a steel substrate with a coating including a layer of aluminum or an aluminum alloy. The method includes selecting a first portion of the first blank to be joined to the second blank, and selecting a second portion of the second blank to be joined to the first portion, and welding the first portion to the second portion. The welding includes using a laser beam and an arc welding torch, wherein the arc welding torch includes a wire electrode, wherein the wire electrode is made of a steel alloy including gammagenic elements, optionally a stainless steel alloy including gammagenic elements and displacing both the laser beam and the arc welding torch in a welding direction, and wherein in the welding direction, the arc welding torch is positioned in front of the laser beam.
