Abstract

PROCEDIMIENTO PARA LA DETECCION DEL PRINCIPIO APROXIMADO DE LA FUSION EN UNA SOLDADURA DE PUNTOS POR RESISTENCIA. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA SE ELIGE ADECUADAMENTE LA RESISTENCIA R DE SOLDADURA Y LA POTENCIA ELECTRICA P SUMINISTRADA A DICHA SOLDADURA; SEGUNDA SE CALCULA LA VELOCIDAD DE VARIACION DE LA RESISTENCIA DE SOLDADURA Y SE DIVIDE POR LA POTENCIA ELECTRICA PARA OBTENER UNA FUNCION VARIABLE CON EL TIEMPO QUE REPRESENTA EL CALOR ESPECIFICO INVERSO DE LA SOLDADURA; Y POR ULTIMO SE EXPLORA LA FUNCION CREADA DETERMINANDO CUANDO SE ALCANZA UN VALOR CORRESPONDIENTE A UNA FRACCION DETERMINADA EMPIRICAMENTE QUE DETERMINA EL INSTANTE DEL COMIENZO DE LA FUSION.
