The device disclosed comprises a support belt (3) for vanes (7) vane drive belts (6) located beside the support belt (3). a vane-feed device and a beam (laser or electron) welding device (11) which welds from the inside, vanes (7) on to the outsides of tube halves (10). When the vanes have been mounted in place on the tube halves (10) the vane/tube-half assemblies are welded together along their longitudinal edges (27) to form complete tubes. These tubes can then be galvanized individually or in bundles for use as heat-exchangers.
L'invention vise un dispositif comportant une courroie-support (3) sur laquelle sont déposées des ailettes (7), et des courroies transporteuses (6) situées à côté de la courroie-support (3), un dispositif d'alimentation (ailettes) et un dispositif de soudage (11) par faisceau (laser ou électrons) qui permet de souder, depuis l'intérieur, des ailettes (7) sur la paroi extérieure de demi-tubes (10). Une fois les ailettes mises en place sur les demi-tubes, ces derniers sont soudés ensemble dans le sens longitudinal (27) pour former des tubes complets. Ces tubes peuvent être galvanisés individuellement ou encore une fois rassemblés en faisceaux destinés aux échangeurs de chaleur.
