Abstract

L'invention est relative à un procédé et une machine de soudage continu d'une ailette hélicoïdale sur un tube. Selon l'invention, on anime le tube 1 d'un mouvement de rotation A horizontale autour de son axe 2, entraînant l'enroulement hélicoïdal sur chant d'un ruban de métal 3 autour du tube 1, puis on soude, au moyen d'un arc électrique issu d'une électrode 4 consommable, ledit ruban à son point de contact sur le tube de manière que l'arc électrique susdit rétablisse sur la partie montante de la surface extérieure du tube. L'invention trouve une application intéressante dans le domaine de la chaudronnerie industrielle.
