Abstract

L'invention concerne les procédés de soudage à l'arc de tubes en spirale. Elle se rapporte à un procédé dans lequel un feuillard 2 est soudé intérieurement et extérieurement avec des électrodes consommables pleines de 3 à 8 mm de diamètre, sous un gaz protecteur comprenant un mélange d'un gaz inerte avec de l'anhydride carbonique ou de l'oxygène, le débit et les positions de soudage étant reglés afin que le cordon de soudure formé n'ait pas de défauts. Application à la fabrication des tubes d'acier soudés en spirale.
