Resumen
En este trabajo se fabricaron electrodos tubulares de diámetro 3.5 mm destinados a la soldadura manual por arco eléctrico (SMAW). La carga utilizada en la fabricación del consumible esta constituida por cascarilla, Aluminio en polvo y ferromanganeso. El empleo de estos elementos en la carga tiene como objetivo evaluar su efecto en la estructura del cordón de soldadura, esencialmente la repercusión del manganeso en la formación de la ferrita acicular y por tanto en las propiedades de resistencia mecánica de la unión.
In this work tubular electrode of diameter 4 mm were manufactured dedicated to the manua welding by electric arch (SMAW). The load used in the production of the consumable one thi constituted by (Fe2O3,Fe3O4,FeO,Fe), powdered Aluminum and ferromanganese. The employment of these elements in the load has as objective to evaluate its effect in the structure o the welding cord, essentially the repercussion of the manganese in the formation of the ferrite acicular and therefore in the properties of mechanical resistance of the union.
