Abstract

PROCEDIMIENTO Y DISPOSITIVO DE CONTROL NO DESTRUCTIVO DE SOLDADURAS POR PUNTOS. EL PROCEDIMIENTO CONSISTE EN UNA PRIMERA PRUEBA MECANICA EN QUE SE DESTRUYEN LAS SOLDADURAS PEGADAS Y EN UNA SEGUNDA PRUEBA EN QUE SE HACE UN CONTROL PUNTUAL DE LA SOLDADURA RESTANTE POR MEDIO DE UN METODO REOMETRICO. LA PRUEBA MECANICA SE EFECTUA MEDIANTE UN UTIL DE PERCUSION FIJADOA SOBRE UN COLUMNA Y ENLAZADO A UNA ELECTROVALVULA QUE PERMITE LA REPRODUCTIBILIDAD DEL PUNTO DEL IMPACTO. EL DISPOSITIVO CONSTA DE UN SISTEMA DE DETECCION FORMADO POR DOS CABEZAS IDENTICAS CADA UNA DE ELLAS CONSTITUIDA POR 2 PARES DE ELECTRODOS DE MEDIDA Y POR 2 PARES DE ELECTRODOS DE ALIMENTACION. LOS ELECTRODOS DE MEDIDA DE UN MISMO PAR ESTAN SITUADOS COMO MAXIMO A 11 MM. Y CADA ELECTRODO DE ALIMENTACION DISTA COMO MAXIMO 2 MM. DE CADA ELECTRODO DE MEDIDA.
