Abstract

Un método para la fabricación continua de tubo soldado relleno de polvo, que incluye las etapas de conformar una tira de metal en un canal abierto, introducir un polvo de relleno en el canal, aproximar los bordes del canal uno contra otro para formar un tubo continuo con una junta longitudinal cerrada, soldar dicha junta longitudinal cerrada para formar un tubo herméticamente cerrado, caracterizado por el hecho de que la cantidad de polvo introducida en el canal es tal que el tubo no está completamente lleno cuando se suelda la junta longitudinal, haciendo la reducción de tamaño subsiguiente que el relleno de polvo quede firmemente compactado en el interior del tubo.
