Abstract

SISTEMA Y METODO DE CONTROL ELECTRONICO DEL PROCESO DE SOLDADURA EN UNA INSTALACION DE SOLDADURA POR RESISTENCIA. SEGUN LA INVENCION EN TODOS Y CADA UNO DE LOS SEMIPERIODOS DEL TIEMPO DE SOLDADURA A PARTIR DEL TERCER SEMIPERIODO I+2 DE LA TENSION DE LINEA UL QUE ALIMENTA EL PRIMARIO DEL TRANSFORMADOR DE SOLDADURA, ES DETERMINADO EL ANGULO DE DISPARO YI+2 DE CADA UNO DE LOS TIRISTORES DEL CONTACTOR ELECTRONICO, EN RELACION AL PASO POR CERO DE DICHA TENSION DE LINEA UL SOBRE LA BASE DE LOS PUNTOS SIGUIENTES: 1. ERIODOS, ANTES; 2.NA CORRIENTE HA CIRCULADO POR EL CIRCUITO DE SOLDADURA, CONTINUACION AL DISPARO DEL TIRISTOR QUE CORRESPONDE AL CONTACTOR ELECTRONICO UTILIZADO, DOS SEMIPERIODOS, ANTES; 3. INTENSIDAD EFICAZ ISI QUE HA CIRCULADO EN EL MISMO TIEMPO DE CONDUCCION TCI EN EL CIRCULO DE SOLDADURA; 4.DESVIACION DE LA INTENSIDAD EFICAZ ISI EN RELACION A LA QUE ES DESEADA IP.
