Ukushiswa kwe-vacuum kungavumela ukuhlanganiswa kwezinto kusetshenziswa into yokugcwalisa engadingi ukushiswa okuhlukile ukuze kugcinwe ama-oxide ephansi. Ukugcina i-vacuum kuyo yonke i-braze kwenza umsebenzi omningi wokugcina i-oxygen ingangeni enkambisweni. Lokhu kubalulekile kumakhasimende anezingxenye ezithile lapho noma yimaphi amakhemikhali noma izinsimbi ezingafakwa ekushisweni zingadala ukungcola okungafuneki ngaphakathi kwesibopho sokugcina. Kuphumela ekuletheni izingxenye ezihlanzekile kakhulu.
Ngenxa yokuthi izitofu zokuhlanza ziklanywe ngokulawulwa kwezinga lokushisa engqondweni, ochwepheshe bezinsimbi bayazi ukuthi isitofu sokuhlanza singashisa izinto zokuhlanza kanye nezingxenye okufanele zihlanganiswe ngokunemba, ukufana, kanye nokuphindeka. Izingxenye eziyinkimbinkimbi yokwakha ezidinga ukuhlanganiswa ezindaweni okunzima ukuzifinyelela, noma izinhlangano ezinenani elikhulu lamalungu zifakwa kalula endaweni yesitofu sokuhlanza.
Ukushiswa kwe-vacuum nakho kuyamangalisa lapho izingxenye ezimbili ezinezingxenye ezincane kakhulu noma ezijiyile kakhulu zidinga ukuxhunywa ngokuqina kwesakhiwo. Izingxenye ezincane zesitoko zithembele ekulawulweni kokushisa okunembile ukuze zingagobeki, kuyilapho izingxenye ezinkulu zesitoko zingathembela ekuqapheni kwe-thermocouple ukuqinisekisa isikhathi esifanele sokucwiliswa, kushiswe ingxenye ngokulinganayo.
Umkhathi kanye nokulawulwa kwezinga lokushisa okutholakala esithandweni somoya ongcolile kuvumela izinga lokushisa elihambisanayo lezingxenye ezinezindawo eziyinkimbinkimbi. Ngokufudumeza nokucima izingxenye ngesivinini esibikezelwayo, isithando somoya ongcolile sinikeza ukulawula okumangalisayo ekuguquleni ingxubevange ye-brazing ibe uketshezi ekushiseni okungeke kuguqule noma kuphambukise izingxenye ezizoboshwa.
Enye inzuzo ebalulekile yokusebenzisa isisombululo se-vacuum brazing yikhono lokulawula imikhiqizo yenqubo. Izinhlelo ze-vacuum furnace zakhiwe ukulawula nokucubungula ukukhishwa kwegesi kangcono kunebhavu likasawoti elifanayo noma isisombululo somoya, futhi azidingi amakhemikhali aqinile noma usawoti oncibilikisiwe okuzodinga ukugcinwa ngokucophelela nokulahlwa. Izindlela zokupheka ze-vacuum brazing ezihlanzekile azidingi ukuhlanzwa okwengeziwe kwezingxenye ngemuva kokucutshungulwa, okunciphisa nokungcola kwamakhemikhali.
