Abstract

Un método para la fabricación de un tubo metálico de boca ancha de un tubo de elemento hueco que tiene a lo largo de su dirección circunferencia, múltiples regiones con diferente resistencia a la deformación, el método de fabricación que tiene: una primera etapa en donde una región de la cual la resistencia a la deformación es relativamente pequeña se identifica tan baja como una resistencia a al deformación y una región para la cual la resistencia a la deformación es relativamente grande comparado con una sección de resistencia a la deformación alta; y una segunda etapa en done un punzón de expansión de tubería se ajusta a presión en el elemento hueco de manera que hace que la velocidad de reducción de grosor de pared de la sección de resistencia a la deformación baja sea menor que la velocidad de reducción de grosor de pared de la sección de resistencia a la deformación alta.
