Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA SOLDADURAS DE ARCO VOLTAICO DE CORTOCIRCUITO, EN QUE UN ALAMBRE DE SOLDADURA LLEVADO CONTINUAMENTE LLEGA ALTERNATIVAMENTE EN UNA FASE DE ARCO VOLTAICO Y EN UNA FASE DE CORTOCIRCUITO, CON LO QUE DURANTE LA FASE DE ARCO VOLTAICO EL ALAMBRE SE ENCUENTRA A DISTANCIA DEL BAÑO DE SOLDADURA DE LA PIEZA DE TRABAJO Y DURANTE LA FASE DE CORTOCIRCUITO EL METAL FUNDIDO TOCA EN EL EXTREMO DEL ALAMBRE DE FUNDICION EL BAÑO DE METAL FUNDIDO Y FINALMENTE SE COLOCA SOBRE LA PIEZA DE TRABAJO POR LA ACCION DEL ATADO QUE ARRANCA EL METAL FUNDIDO DEL ALAMBRE. LA MEJORA CONSISTE EN QUE ESTA PREVISTO UN CIRCUITO DE MANDO DE CORRIENTE (22) CON ELEVADA INDUCTIVIDAD QUE CONDUCE CONTINUAMENTE UNA CORRIENTE BASICA DE PEQUEÑA FUERZA QUE APOYA EL ARCO ENTRE EL ALAMBRE DE SOLDADURA Y LA PIEZA DE TRABAJO, Y QUE ESTA PREVISTO UN SEGUNDO CIRCUITO DE MANDO DE CORRIENTE (24) QUE GOBIERNA EL FLUJO DE CORRIENTE DURANTE LA FASE DE ARCO VOLTAICO DEL PROCES DE FUNDICION. ESTE SEGUNDO CIRCUITO DE MANDO DE CORRIENTE (24) MUESTRA MEDIOS DE RETARDO DE TIEMPO QUE PERMITEN TOMAR UNA ZONA DE ARCO VOLTAICO EN EL COMIENZO DE LA FASE DEL ARCO VOLTAICO, QUE SE DETERMINA EN PRIMERA LINEA DE LA CORRIENTE BASICA PARA UN TIEMPO PRESELECCIONADO PREVIAMENTE, DURANTE EL QUE EL METAL FUNDIDO SE LLEVA EN LA PUNTA DEL ALAMBRE DE SOLDADURA Y EN EL BAÑO DE FUNDICION DE METAL POR TENSION SUPERFICIAL CONTRA EL ALAMBRE Y/O EN EL BAÑO DE FUNDICION, CON LO QUE SE OPRIME HACIA ABAJO Y SE PREVEN MEDIOS QUE PERMITEN CIRCULAR UN ELEVADO SALTO DE CORRIENTE POR EL ARCO VOLTAICO ENTRE EL ALAMBRE Y EL BAÑO DE SOLDADURA CON UNA ENERGIA SELECCIONADA PREVIAMENTE PARA FUNDIR UN VOLUMEN RELATIVAMENTE CONSTANTE DE METAL EN EL EXTREMO DEL ALAMBRE Y A DISTANCIA DEL BAÑO DE FUNDICION. ESTE ELEVADO IMPULSO DE ENERGIA TIENE LUGAR EN LA PROXIMIDAD DEL COMIENZA DE LA FASE DEL ARCO VOLTAICO Y FINALIZA EN GENERAL DELANTE DEL PUNTO MEDIO DE LA FASE DEL ARCO VOLTAICO, DE MODO QUE EL ALMABRE SE FUNDE PRIMERAMENT E Y SEGUIDAMENTE SE CONDUCE EN EL BAÑO DE FUNDICION DE METAL, POSTERIORMENTE EL BAÑO SE PRESIONA HACIA ABAJO O QUEDA EN REPOSO.
