Abstract

METODO Y DISPOSITIVO PARA CONTROLAR UNA FUENTE DE ENERGIA PARA SOLDADURA POR ARCO DE MANERA QUE SE REDUZCAN LAS SALPICADURAS CUANDO SE EMPLEA LA FUENTE DE ENERGIA PARA DEPOSITAR METAL DE UN ALAMBRE O ELECTRODO DE SOLDAR EN LA PIEZA DE TRABAJO POR EL MODO DE TRANSFERENCIA POR CORTOCIRCUITO DENTRO DE UNA CORRIENTE DE SOLDADURA QUE HACE QUE EL ALAMBRE DE SOLDADURA ALTERNE ENTRE UNA CONDICION DE CORTOCIRCUITO Y UNA CONDICION DE ARCO TENIENDO LUGAR LA TRANSFERENCIA DE METAL DURANTE LA CONDICION DE CORTOCIRCUITO. ESTE METODO Y DISPOSITIVO INCLUYE EL CONCEPTO DE DESPLAZAMIENTO DE LA CORRIENTE DE SOLDADURA A UN VALOR DE CORRIENTE DE FONDO (IB) EN RESPUESTA A LA CONDICION DE CORTOCIRCUITO, MANTENIENDO LA CORRIENTE DE SOLDADURA GENERALMENTE EN EL NIVEL DE LA CORRIENTE DE FONDO (IB) DURANTE UN TIEMPO PRESELECCIONADO (T1), PERMITIENDO ENTONCES QUE LA CORRIENTE DE SOLDADURA ALCANCE EL NIVEL DE CORRIENTE NORMAL Y NO IMPEDIDO (IP), Y PRODUCIENDO EL ESTADO DE ESPERA A SER FINALIZADO ANTES DEL TIEMPO PRESELECCIONADO EN RESPUESTA A UNA CONDICION DETECTADA DE ARCO. ESTE CONCEPTO PROVEE UNA CONDICION DE CORRIENTE REDUCIDA PREDETERMINADA INMEDIATAMENTE POR ENCIMA ESTABLECIENDOSE UN CORTOCIRCUITO ENTRE EL ALAMBRE O ELECTRODO DE SOLDADURA Y LA PIEZA DE TRABAJO, EN DONDE DICHA CONDICION DE CORRIENTE REDUCIDA SE RETIENE LO BASTANTE PARA TRANSFORMAR LO QUE DE OTRA FORMA PASARIA DE SER UN CORTO CIRCUITO MOMENTANEO CARGADO DE SALPICADURAS EN UN CORTOCIRCUITO EN EL QUE SE TRANSFIERE EL METAL A LA PIEZA DE TRABAJO. ADEMAS, EL METODO Y DISPOSITIVO DETECTAN LA PENDIENTE DE LA CORRIENTE O TENSION DE SOLDADURA Y DESPLAZAN LA CORRIENTE DE SOLDADURA AL NIVEL DE CORRIENTE REDUCIDA DE FONDO (IB) CUANDO LA CORRIENTE ALCANZA EL VALOR MAXIMO JUSTO ANTES DE LA PERDIDA DEL METAL DESDE EL ALAMBRE PARA REDUCIR ASI LA ENERGIA DE SALPICADO CUANDO EL METAL FUNDIDO SE DESPRENDE DESDE EL ALAMBRE.
