Abstract

Un inserto de aleta forma los bordes de una banda metálica reforzada antes de formar la banda en un tubo y soldarla. Los bordes de la banda metálica se forman de modo que los bordes longitudinales de la porcion no reforzada de la banda entran en contacto durante la soldadura reduciendo por lo tanto las fluctuaciones en el volumen del metal en el sitio de soldadura que causan inestabilidad de la soldadura.
