The invention relates to a method for manufacturing finned tubes made of metal, in particular heat exchanger tubes, wherein at least one continuous strip (4) forming the fins (1) is fed tangentially to a tubular body (2) that is set into rotational motion, said strip wound onto the tubular body, the side of the strip (4) facing the tubular body (2) is connected to the tube surface by way of a welding device (7,8) using a filler material (9), and the strip (4) to be wound is fed just behind the welding area between guide discs (12) that extend toward the surface of the tube and to the point of welding up to the point of being flush therewith. In order to increase the life of the guide discs (12), the guide discs (12) are cooled using cooling water to which about vol.-% of a welding release agent is added.
L'invention concerne un procédé de fabrication de tubes nervurés en métal, en particulier de tubes d'échangeur de chaleur, selon lequel au moins un feuillard (4) sans fin formant les nervures (1) est amené tangentiellement sur un corps tubulaire (2) mis en rotation et enroulé sur ce dernier. Le côté du feuillard (4) tourné vers le corps tubulaire (2) est relié à la surface du tube au moyen d'un dispositif de soudage (7, 8) qui utilise un métal d'apport (9) et le feuillard (4) enroulé est guidé entre des disques de guidage (12), légèrement en arrière de la zone de soudage, ces disques s'approchant jusqu'à venir en contact avec la surface du tube et le site de soudage. Pour augmenter la durée de vie des disques de guidage (12), ces derniers (12) sont refroidis avec de l'eau de refroidissement à laquelle on ajoute environ 10 % en volume d'un agent de séparation de soudure.
