Abstract

L'INVENTION CONCERNE UN PROCEDE DE RACCORDEMENT DES ELEMENTS DE TUYAUTERIE EN PLASTIQUE SOUDABLE PAR SOUDAGE DE LEURS EXTREMITES A L'AIDE D'UNE RESISTANCE ELECTRIQUE CHAUFFANTE. LE PROCEDE SELON L'INVENTION EST CARACTERISE PAR LE FAIT QU'A PARTIR DE LA MESURE DE LA TENSION DE SOUDAGE, EST MATERIALISEE LA FONCTION CARREE DE LA VALEUR MESUREE, CONVERTIE ENSUITE EN UNE FREQUENCE D'IMPULSIONS CORRESPONDANTES, LES IMPULSIONS ETANT DENOMBREES PAR UN COMPTEUR ET L'OPERATION DE SOUDAGE INTERROMPUE DES QUE LE COMPTEUR ATTEINT UN NOMBRE PRESELECTIONNE. APPLICATION AU RACCORDEMENT DES TUYAUTERIES.THE INVENTION CONCERNS A PROCESS FOR CONNECTING PIPING ELEMENTS IN WELDABLE PLASTIC BY WELDING THEIR ENDS USING AN ELECTRIC HEATING RESISTOR. THE PROCESS ACCORDING TO THE INVENTION IS CHARACTERIZED BY THE FACT THAT FROM THE MEASUREMENT OF THE WELDING VOLTAGE, THE SQUARE FUNCTION OF THE MEASURED VALUE IS MATERIALIZED, THEN CONVERTED INTO A CORRESPONDING PULSE FREQUENCY, THE PULSES BEING NUMBERED BY ONE. COUNTER AND THE WELDING OPERATION INTERRUPTED AS SOON AS THE COUNTER REACHES A PRESELECTED NUMBER. APPLICATION TO PIPING CONNECTION.
