Abstract

L'invention concerne un procédé de soudage du joint longitudinal d'un tube. Ce procédé qui utilise des pattes d'amorçage et de fin de soudage 2 soudées à la tôle de départ 1 avant le roulage de cette dernière, consiste à souder à vitesse réduite à un taux commandé dans la zone finale et à réduire également l'énergie transmise aux électrodes. Application au soudage de tubes.
