Abstract (English): Performance of the microstructure cast iron joints with different material was characterized after applying the thermal welding cycle. For the metallurgical joint in cast iron plates 10 millimeters thick and V preparation at 60 °, E 309L-16, UTP 8 and UTP 86 FN electrodes were selected. With E 309L - 16, the solidification is of a Widmanstátten or acicular austenite morphology with presence of carbides and with UTP 8 a ferritic matrix is obtained with formation carbides inside. Both are prone to cracking; for the UTP 86 FN an austenitic structure was obtained with a small amount of delta ferrite and a better solidification. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): Se caracterizó el comportamiento de la microestructura de uniones de hierro fundido con diferentes materiales luego de ser aplicado el ciclo térmico de soldadura. Para la unión metalúrgica en planchas de hierro fundido de 10 mm de espesor y con preparación en V a 60o se seleccionaron los electrodos E 309L-16, el UTP 8 y el UTP 86 FN. Con el E 309L-16 la solidificación fue de una morfología de austenita Widmanstátten o acicular, con presencia de carburos y con el UTP 8 se obtuvo una matriz ferrítica con la formación de carburos en el interior, ambas solidificaciones propensas al agrietamiento. Para UTP 86 FN se obtiene una estructura austenítica con una pequeña cantidad de ferrita delta y mejor solidificación. [ABSTRACT FROM AUTHOR]
