Abstract

METODO PARA PREPARAR TOCHOS DE EXTRUSION MULTIMETALICOS. CONSISTE EN EL EMPLEO DE SOLDADURA POR HAZ ELECTRONICO EN EL VACIO PARA UNIR LOS EXTREMOS DE LOS ELEMENTOS DE TOCHO A TRAVES DE LAS SIGUIENTES OPERACIONES: 1 ENCAJAR AL MENOS UN ELEMENTO DE TOCHO EXTERIOR. 2 COLOCAR DICHOS ELEMENTOS EN UNA CAMARA DE VACIO. 3 SOLDAR ENTRE SI LOS EXTREMOS DE LOS TOCHOS UTILIZANDO SOLDADURA POR HAZ ELECTRONICO BAJO VACIO. LA SOLDADURA TIENE LUGAR DIRIGIENDO SOBRE AMBOS EXTREMOS DE LOS ELEMENTOS DE TOCHO ENCAJADOS, UN HAZ DE ELECTRONES QUE AFECTA TODA LA PERIFERIA DE UNA INTERFICIE DEFINIDA ENTRE LOS TOCHOS. LAS SUPERFICIES DE SEPARACION ENTRE LOS ELEMENTOS SE MECANIZAN HASTA OBTENER UN ACABADO DE 3,810 MILIMICROMETROS O MENOS ANTES DEL ENCAJE. ANTES DE DICHO ENCAJE, SE LIMPIAN LAS SUPERFICIES DE SEPARACION ENTRE LOS ELEMENTOS EMPLEANDOSE DISOLVENTES A BASE DE 1,1,1-TRICLOROETANO, METANOL Y ACETONA.
