Zusammenfassung:	Welding line for prodn. of coiled tubing from coiled strip comprises (i) a coil handling station consisting of a reel, which can be moved transversely w.r.t. the line, and a bobbin which carries the strip coils; (ii) a strip butt-joining assembly; (iii) strip shaping, seam welding and advancement stations, (iv) a tube coiling station including bending rolls; (v) a coiled tube receiving station including guide rollers controlled by the same controller as the bending rolls; and (vi) a device for cutting the tubing into lengths, positioned downstream of the bending rolls. The guide rollers are mounted on a platform which can be inclined w.r.t. the axes of the bending rolls and is connected to the output shaft of the controller via a universal joint. The welding line is esp. useful for prodn. of thin-walled tubing (esp. tubing having an o.d. to wall thickness ratio of about 60) at welding speeds of about 15 m/min. The line produces tube coils of the required length independently of the lengths of the strip coils and operates continuously without requiring rethreading of the tube into the bending rolls. L'INVENTION CONCERNE LA FABRICATION DE TUBES.LE TRAIN DE SOUDAGE DE TUBES FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QUE LE DISPOSITIF DE TRONCONNAGE 19 EST PLACE EN AVAL (SUIVANT LE SENS DE DEFILEMENT DE LA SPIRE DE TUBE) DES GALETS DE CINTRAGE 9 DU DISPOSITIF 8 D'ENROULEMENT EN GLENE, ET EN CE QUE LES CYLINDRES DE GUIDAGE 11 DU DISPOSITIF DE RECEPTION 10 SONT MONTES SUR UNE PLATE-FORME 12 INCLINABLE PAR RAPPORT AUX AXES DES GALETS DE CINTRAGE 9 ET SONT RELIES A L'ARBRE DE SORTIE DE LEUR COMMANDE COMMUNE AVEC LES GALETS DE CINTRAGE 9 PAR L'INTERMEDIAIRE D'UNE CHARNIERE UNIVERSELLE.LE TRAIN DE SOUDAGE FAISANT L'OBJET DE L'INVENTION PEUT ETRE UTILISE AVEC SUCCES NOTAMMENT POUR LA FABRICATION DE TUBES A PAROI MINCE, EN PARTICULIER DE TUBES DONT LE RAPPORT DU DIAMETRE EXTERIEUR A L'EPAISSEUR DE LA PAROI EST VOISIN DE 60.
