(1) Txo qhov chaw sib txhuam kom tsawg li ntau tau kom tiv thaiv thiab txo cov kab nrib pleb, yog li ua kom lub cuab yeej siv tau ntev dua.
(2) Lub zog vuam yog ua kom ntseeg tau los ntawm kev siv cov ntaub ntawv vuam muaj zog thiab siv cov txheej txheem brazing kom raug.
(3) Xyuas kom tseeb tias cov khoom siv vuam ntau dhau tsis lo rau lub taub hau ntawm lub cuab yeej tom qab brazing, pab txhawb kev sib tsoo ntug. Cov ntsiab cai no txawv ntawm cov uas siv yav dhau los rau cov cuab yeej sib xyaw ua ke ntau hniav, uas feem ntau muaj cov qauv tsim qhov kaw lossis ib nrab kaw. Qhov kawg tsis yog tsuas yog ua rau muaj kev ntxhov siab brazing thiab qhov tawg, tab sis kuj ua rau kev tshem tawm slag nyuaj thaum lub sijhawm brazing, ua rau muaj slag ntau dhau hauv qhov weld thiab kev sib cais loj heev. Ntxiv mus, vim yog kev tsim qhov groove tsis raug, cov khoom siv vuam ntau dhau tsis tuaj yeem tswj tau thiab sib sau ua ke ntawm lub taub hau cuab yeej, ua rau muaj teeb meem thaum sib tsoo ntug. Yog li ntawd, yuav tsum tau them sai sai thaum tsim cov cuab yeej sib xyaw ua ke ntau hniav.
Cov khoom siv vuam yuav tsum muaj qhov ntub dej zoo nrog ob qho tib si cov hlau tawv uas raug brazed thiab cov hlau substrate.
Nws yuav tsum xyuas kom meej tias lub vuam muaj zog txaus ntawm qhov kub thiab txias hauv chav tsev thiab qhov kub siab (vim tias ob qho tib si cov cuab yeej sib xyaw ua ke thiab qee cov pwm muaj qhov kub sib txawv thaum siv).
Thaum ua kom ntseeg tau cov xwm txheej saum toj no, cov khoom siv vuam yuav tsum muaj qhov qis dua kom txo tau kev ntxhov siab ntawm kev sib txhuam, tiv thaiv kev tawg, txhim kho kev ua haujlwm ntawm kev sib txhuam, thiab txhim kho cov xwm txheej ua haujlwm rau cov neeg teb xov tooj.
Cov khoom siv vuam yuav tsum ua kom pom tias nws kub thiab txias zoo kom txo tau kev ntxhov siab ntawm kev vuam. Nws yuav tsum muaj kev ntws zoo thiab kev nkag tau zoo, nrog rau qhov no tseem ceeb heev thaum vuam cov cuab yeej txiav ntau hniav sib xyaw thiab cov pwm sib xyaw loj.
Cov khoom siv vuam yuav tsum tsis txhob muaj cov khoom uas muaj cov ntsiab lus qis evaporation, kom tiv thaiv cov evaporation ntawm cov khoom no thaum lub sijhawm brazing cua sov thiab cuam tshuam rau qhov zoo ntawm weld.
Cov khoom siv vuam yuav tsum tsis txhob muaj cov hlau muaj nqis, cov hlau tsis tshua muaj, lossis cov khoom uas ua rau tib neeg noj qab haus huv tsis zoo.
