Abstract

Procédé pour éviter les défauts d'extrémité des joints de soudure de tubes, réalisés au moyen de plusieurs électrodes, notamment sous poudre protectrice, et en particulier à des vitesses de soudure élevées et avec utilisation de pièces de prolongement du joint rapportées avant cintrage. Selon l'invention, ce procédé est caractérisé en ce que, pendant la phase de démarrage de la soudure, la vitesse de soudure est augmentée de façon uniforme ou par paliers de zéro à la valeur nominale, de sorte que la géometrie définitive du joint de soudure soit obtenue avant la transition entre les pièces auxiliaires rapportées et le tuyau. Fabrication de tubes par roulage de tôle et soudage
