Abstract

L'invention se rapporte au domaine de la construction mécanique, et notamment à la fabrication de tubes de petit diamètre et de faible épaisseur à soudure longitudinale. Cette invention concerne essentiellement un procédé qui consiste à former une ébauche tubulaire que l'on déplace dans le sens de la longueur, et à souder les bords de jonction par faisceau laser. Lors de la formation de l'ébauche, on donne à sa section transversale la forme d'une ellipse. Dans un même temps, on plie l'ébauche dans le sens de sa longueur selon un arc donné. Le dispositif comprend une source laser avec un système de focalisation, des cages de laminoir de mise en forme avec des galets profilés, et une cage de soudage avec des cylindres. Les galets sont disposés selon un arc, tandis que les cylindres sont installés de manière à comprimer l'ébauche tubulaire. Le point de jonction des bords de l'ébauche et le centre du rayon de courbure maximal sont situés sur une même droite qui passe par le plan de jonction.
