Resumen

En esta investigación se estudió la soldabilidad de uniones de un acero templado y revenido para blindajes del tipo MIL A46100 (Fe; 0,28% C; 0,30% Cr; 0,24% Mo y 0,20% Ni), usando metal de aporte AWS E11018M, y el proceso Smaw (soldadura al arco eléctrico con electrodo revestido), a través de relaciones generadas entre microestructura, variables del proceso y propiedades mecánicas (tracción, impacto Charpy V y microdurezas), en juntas de soldadura. Asimismo se evaluó el agrietamiento en frío a través de dos ensayos (severidad térmica controlada y placa H), y el desempeño en servicio (balístico) de las mismas, obtenidas al practicar uniones con dos entradas de calor, denominadas alta y baja. Se estableció la incidencia del aporte calórico sobre las propiedades y el desempeño.
