Abstract

On découpe dans une feuille en matériau métallique au moins une plaque plane (20) comportant une partie principale ayant la forme développée de la paroi de l'élément de structure et au moins une partie complémentaire (26, 27, 28) de recouvrement et de fixation, on plie la plaque découpée (20) selon une pluralité de lignes (23) de façon à former la paroi de l'élément de structure comportant plusieurs tronçons annulaires non alignés axialement à partir de portions pliées (22, 24, 24', 25) de la partie principale de la plaque découpée (20) et on fixe par soudage au moins une partie complémentaire de recouvrement et de fixation (26, 27, 28) sur l'une au moins d'une portion pliée (22, 23, 24', 25) et d'une seconde partie de recouvrement. Pendant le soudage, l'au moins une partie de recouvrement (26, 27, 28) et la portion pliée de paroi (22, 24, 24', 25) ou la seconde partie de recouvrement sont maintenues en appui élastique l'une sur l'autre, dans une disposition superposée. De préférence, le soudage est réalisé par un faisceau laser, en transparence. L'élément de structure suivant l'invention connaît de nombreuses applications dans des industries très diverses.
