Abstract
PROCEDIMIENTO DE MEDICION PARA DETERMINAR DEFECTOS EN COSTURAS DE SOLDADURA DE PIEZAS DE TRABAJO METALICAS. CARACTERIZADO PORQUE LAS LONGITUDES MEDIDAS DE LAS PIEZAS SE ACOPLAN CORRECTAMENTE EN LONGITUD CON UN RESULTADO DE COMPROBACION ULTRASONICO LOGRADO, PARA LA DETERMINACION DE SUPERFICIES DE DEFECTO; PORQUE LAS SUPERFICIES DE DEFECTO AVERIGUADAS SE CLASIFICAN Y SE COMPARAN CON UN CATALOGO DE CLASES DE DEFECTOS; Y PORQUE LAS SEÑALES DE DEFECTO ULTRASONICAS PRODUCIDAS EN UNA COMPROBACION DE COSTURA DE SOLDADURA Y AVERIGUADAS POR PROCESAMIENTOS DE IMPULSOS REFLEJADOS, SE DIGITALIZAN Y SE ACOPLAN POR CALCULO CON SEÑALES DE MEDICION LONGITUDINAL DE LA SECCION DE PIEZA DE TRABAJO ASOCIADA, FORMANDOSE UNA SUPERFICIE DE DEFECTO INDICATIVA A MODO DE RETICULA.
