Abstract

Le procédé selon l'invention consiste à faire passer une bande d'acier à travers un four de préchauffage 12 et ensuite à travers un four de chauffage 14 vers une machine à former et à souder les tubes en bout pour obtenir un tube d'acier soudé il en mesurant la température d'au moins un bord et de la partie centrale de la bande au moyen d'un détecteur de température 32, à comparer les valeurs de ces deux températures dans un ordinateur 36 pour déterminer la différence entre la température theta E du bord et la température theta C de la partie centrale pour comparer cette difference avec la difference correspondante des valeurs de référence 44 et 46 pour commander la vitesse d'entraînement et le débit de combustible de chauffage afin de compenser les variations de l'épaisseur de la bande dans le sens longitudinal.
