I-Ultrasonic metal welding yatholakala ngengozi ngawo-1830. Ngaleso sikhathi, lapho i-electrode ye-welding yamanje yengezwa ekuhlolweni kokudlidliza kwe-ultrasonic, kwatholakala ukuthi yayingashiselwa ngaphandle kwamanje, ngakho kwasungulwa ubuchwepheshe bokushisela obubandayo bensimbi be-ultrasonic. Nakuba ukushisela kwe-ultrasonic kutholwe ngaphambili, kuze kube manje, indlela yokusebenza kwayo ayikacaci. Kufana ne-friction welding, kodwa kukhona umehluko. Isikhathi sokushisela i-Ultrasonic sifushane kakhulu futhi izinga lokushisa liphansi kune-recrystallization; iphinde ihluke ekushiseni kwengcindezi, ngoba ingcindezi ye-static esetshenziswayo incane kakhulu kune-pressure welding. Ngokuvamile kukholakala ukuthi esigabeni sokuqala senqubo yokushisela i-ultrasonic, i-oxide endaweni yensimbi inyakaziswa nge-tangentially, futhi ingxenye ephumayo ye-rough surface ikhiqiza izinqubo ze-microwelding eziphindaphindiwe kanye nokubhubhisa ukwandisa indawo yokuxhumana nokwandisa izinga lokushisa le-welding zone High, ukuguqulwa kwepulasitiki kwenzeka esibonakalayo se-weldment. Ngale ndlela, lapho ingcindezi yokuxhumana iseduze komunye nomunye ibanga lapho amandla adonsela phansi e-athomu angenza khona, kwakhiwa i-solder joint. Uma isikhathi sokushisela siside kakhulu, noma i-amplitude ye-wave ye-ultrasonic inkulu kakhulu, amandla okushisela azoncishiswa, noma abhujiswe.
Izici ze-ultrasonic metal welding
Izici ze-ultrasonic metal welding yilezi: asikho isidingo sokufudumeza nokushisa kwangaphandle, akukho deformation ngenxa yokushisa, akukho ukucindezeleka okusalayo, kanye nezidingo eziphansi zokwelashwa kwangaphambili kwe-welding ebusweni be-weldment. Akuzona kuphela izinsimbi ezifanayo kodwa nezinsimbi ezihlukene zingashiselwa. Amashidi azacile noma imicu ingashiselwa emapuletini awugqinsi. I-Ultrasonic welding inamandla amancane kakhulu kune-welding yamanje, futhi ivame ukusetshenziselwa ukushisela imikhondo yama-transistors noma amasekethe ahlanganisiwe. Uma isetshenziselwa ukufakwa uphawu kwe-welding yezidakamizwa nezinto eziqhumayo, ingagwema ukushisela okuvamile ekungcoliseni imithi ngenxa yezinto ezincibilikisiwe, futhi ngeke kuqhume ngenxa yokushisa nokunye.
