Ngokufana ne-resistance welding, i-resistance brazing isebenzisa ukushisa ezintweni zebhondi ezine-conductivity ephezulu kagesi.Njengoba kuboniswe igama layo, le nqubo isebenzisa isimiso sokumelana nokukhiqiza ukushisa okudingekayo ekusebenzeni kwayo;njengoba amandla kagesi egeleza kumjikelezo ohlanganisa i-workpiece, ukumelana kwesekethe kukhiqiza ukushisa.
Njenge-resistance welding nezinye izindlela zokushisela, i-resistance brazing idinga imishini ekhethekile-imvamisa i-transformer, ama-electrode, nomthombo wokucindezela.Umehluko wayo oyinhloko ukuthi uhilela ukusetshenziswa kwensimbi eyengeziwe yokuhlanganisa ukuze kuhlanganiswe izingxenye ndawonye.
Ukusebenza kwe-resistance brazing ngokuvamile kuhlanganisa izigaba ezilandelayo:
1. Ukulungiselela zonke izakhi, okuhlanganisa ama-electrode, ukususa ukungcola okungaphezulu.
2. Ukulungisa zonke izingxenye emhlanganweni.
3. Ukusungula umjikelezo ohlanganisa i-workpiece.
4. Ukubeka impahla yokugcwalisa (ngokuvamile ekwakhiwe ngaphambili noma ku-foil) phakathi kwezindawo ezihlangene.
5. Ukusebenza kwamanje ngesekethe ukuze kukhiqizwe ukushisa okudingekayo ukuze kuncibilike impahla yokugcwalisa futhi kuthuthukiswe isibopho se-metallurgical phakathi kwama-substrates.
6. Ukucisha amandla kagesi nokugcina ingcindezi ukuvumela into yebrazi ukuthi iqine futhi yakhe ukuxhumana okuqinile phakathi kwezingxenye ezimbili.
7. Ukukhipha ilunga eliqediwe ku-fixture nokukhipha noma iyiphi i-flux esele.
8. Ukuhlola ilunga eliqediwe.
Uma kuqhathaniswa nezinye izindlela zokushisela, i-resistance brazing inikeza izinzuzo eziningana.Isibonelo, ngokungafani ne-welding yendawo yendabuko, i-resistance brazing inikeza okulandelayo:
● Amazinga okushisa aphakeme ukuze kuhlanganiswe izinsimbi eziguquguqukayo, njengethusi noma ithusi, ebezingeke zihlanganiswe ngenye indlela.
● Ukusebenza okulula njengoba ukuqiniswa kokuqina kudinga kuphela ukuletha impahla yokugcwalisa endaweni yayo yokuncibilika, hhayi ucezu lomsebenzi ngokwalo.
● Ukushisisa okwasendaweni okwengeziwe, okuqinisekisa ukuthi ezinye izingxenye ze-workpiece zihlala zivikelekile futhi zigcina amandla azo.
● Izindleko eziphansi zokutshala izimali njengoba okokusebenza okudingekayo kubiza kancane.
● Ukuphatheka okukhulu kuyasiza ekucubunguleni izisetshenziswa ezinkulu ezingakwazi ukuthuthwa kalula.
Nakuba i-resistance brazing inikeza izinzuzo eziningi, kungase kungabi ukukhetha okufanele kulo lonke uhlelo lokusebenza.Ngenxa yokusetshenziswa kokushisa kwendawo, ama-workpieces angahlanekezelwa.Izinto zokwakha ze-Brazing nazo zidinga ukuba namaphuzu aphansi ancibilikayo, njengoba i-workpiece yenziwe ngezinto ezisebenza kakhulu.Ukwengeza, inqubo ayilungile ezindaweni ezinkulu ezihlangene;iyasebenza kakhulu ukuthi isetshenziswe emalungeni amancane.
Yize ingafaneleki kuzo zonke izimo, i-resistance brazing iyazuzisa izinhlelo eziningi zokukhiqiza ngenxa yayo:
● Ikhono lokwenza izibopho ezihlala njalo phakathi kwezinto eziyisisekelo.
● Izindleko ezingokomnotho zemihlangano elula neyinkimbinkimbi.
● Amazinga okushisa aphansi kanye nokusabalalisa ukushisa okulinganayo uma kuqhathaniswa nokushisela.
● Ukusebenza kahle ekuhlanganiseni izinsimbi ezincane neziwugqinsi.
● Amandla okugcina ukubekezelela okuqinile kwe-dimensional.
