Abstract

La invencion describe un proceso para la produccion de estructuras de marco diseñadas como perfiles metálicos para tubos de rayos catodicos y es particularmenteutil en la produccion de cinescopios y monitores. La produccion de estructuras sin terminar se realiza al soldar al menos dos componentes de inicio, seguido por la formacion, en donde los componentes de inicio diseñados como superficies planas se colocan y fijan en sus posiciones, de una manera tal que los bordes de los componentes de inicio que se van a soldar entre en contacto, directo; seguido por la soldadura de las uniones de los componentes de inicio con al menos un haz de láser; y subsecuentemente procesar de manera convencional la estructura sin terminar producida usando al menos dos costuras de soldadura al prensar y/o troquelar. El haz de láser se genera usando un láser de gas de CO2 o un láser de componentes solidos de Nd: YAG.
