Abstract

L'invention porte sur un procédé de fabrication d'un élément structural tubulaire consistant à façonner une ébauche de tube (10) afin d'obtenir une épaisseur (t1, t2, t3) de paroi constante sur le pourtour mais variable sur la longueur et à former l'ébauche (10) afin d'obtenir l'élément structural souhaité (90). L'opération de formage fait intervenir de préférence l'hydroformage.
