Abstract

Procedimiento para fabricar un tubo con soldadura longitudinal a partir de un recorte plano de chapa con bordes longitudinales paralelos, en el que el recorte (B) de chapa se transforma en un tubo con ranura mediante dos mitades (2, 3) del útil de moldeo, desplazables una contra otra, dispuestas entre sí con simetría especular y con semiconchas (8) externas cilíndricas y a continuación se sueldan entre sí los bordes longitudinales en el punto culminante del útil de moldeo, que se mantienen en la posición mediante las mitades (2, 3) del útil de moldeo, caracterizado porque el recorte (B) de chapa se apoya internamente durante el moldeado mediante mitades (10) cilíndricas de mandril interno que están asignadas fijamente a las semiconchas externas (8) y forman con éstas la ranura (9) del molde, manteniéndose libres para la soldadura los bordes longitudinales que salen en el punto culminante.
