Abstract

Un metodo per realizzare elementi preformati (1) per la saldatura, in particolare la saldobrasatura, di componenti e parti metalliche (15,16) comprende una successione di fasi in cui delle polveri (11) di materiale disossidante in sè noto vengono associate a polveri (10) di un'usuale lega di brasatura ed a granuli (12) di materia organica legante, l'insieme così ottenuto venendo finemente polverizzato e sottoposto a pressatura così da realizzare l'elemento preformato (1) desiderato. L'elemento ottenuto attraverso l'attuazione del metodo sopra citato presenta un corpo comprendente polveri di materiale disossidante noto qualsiasi, polveri di un'usuale lega di brasatura dispersa in modo omogeneo in una materia organica legante, detto corpo avendo una forma ben definita e stabile.
