20.500.12556/RUL-102495 Analiza spajanja električnega kontakta med žico in temperaturnim senzorjem Analysis of joining of the electrical contact between a wire and the temperature sensor V elektroindustriji je treba pogosto meriti temperaturo v izdelkih, kot so na primer elektromotorji. V ta namen se v te elemente vstavlja temperaturne senzorje, pri katerih je pomemben spoj med temperaturnim senzorjem in žico. Obstoječ temperaturni senzor, ki je spojen z vročim spajkanjem, je finančno neugoden. V magistrskem delu so predstavljeni tudi drugi možni postopki spajanja, ki bi lahko v eni napravi za sestavljanje spojili tako kovine kot tudi polimere. V pregledu literature sta podrobno opisana postopka ultrazvočnega varjenja in laserskega varjenja kovin in polimerov. Detajlno je popisan potek eksperimentalnega spajanja električnih kontaktov med posrebreno bakreno pletenico in vodnikom temperaturnega zaznavala. Ultrazvočno in lasersko varjenje sta v magistrskem delu analizirana na varjenju vodnika temperaturnega zaznavala L 420 in posrebrene bakrene pletenice. Zaradi spajanja tankih žic ultrazvočno spajanje ni dalo ponovljivih rezultatov, med tem ko smo z laserskim varjenjem dosegli dobre trdnostne lastnosti spoja in ponovljivo kakovost zvara. In the electrical industry, temperature in products, such as electric motors, must often be measured. For this purpose, temperature sensors are inserted into these elements, for which the joint between the contact sensor and the wire is important. An existing temperature sensor that is welded with hot soldering is financially unfavorable. In my master's thesis,other possible merger procedures which could combine both metals and polymers in one assembly machine are presented. In the literature review, both ultrasonic and laser welding of metals and polymers are described in detail. The course of experimental fusing of electrical contacts between the silver-plated copper wire and the temperature sensor is described minutely. In the master's thesis, both ultrasonic and laser welding are analyzed on the welding of the temperature sensor L 420 and silver-plated copper wire. Because of joining thin wires, ultrasonic welding didn't give repeatable results, while we achieved good properties of the joint and repeatable weld quality with laser welding. ultrazvočno varjenje lasersko varjenje Ryton posrebren paladijev vodnik temperaturno zaznavalo pozlačena bakrena pletenica ultrasonic welding laser welding Ryton silver plated palladium conductor temperature sensor silver plated copper wire true false false [A.
