(1) Txo qhov brazing cheeb tsam kom ntau li ntau tau los tiv thaiv thiab txo cov kab nrib pleb, yog li txhim kho lub cuab yeej lub neej.
(2) Lub zog vuam yog ua kom ntseeg tau los ntawm kev siv cov khoom siv vuam zoo thiab siv cov txheej txheem brazing kom raug.
(3) xyuas kom meej tias cov khoom siv vuam ntau dhau tsis ua raws li lub taub hau ntawm lub cuab yeej tom qab brazing, yooj yim rau kev sib tsoo ntug.Cov ntsiab cai no txawv ntawm cov siv yav dhau los rau cov cuab yeej siv tawv tawv tawv, uas feem ntau nthuav tawm cov qauv kaw lossis ib nrab kaw.Lub tom kawg tsis tsuas yog nce brazing kev nyuaj siab thiab tawg tshwm sim, tab sis kuj ua rau slag tshem tawm nyuaj thaum lub sij hawm brazing, ua rau ntau dhau slag entrapment nyob rau hauv lub weld thiab loj detachment.Tsis tas li ntawd, vim yog qhov tsis tsim nyog groove tsim, cov khoom siv vuam ntau dhau tsis tuaj yeem tswj tau thiab khaws cia ntawm lub cuab yeej lub taub hau, ua rau muaj teeb meem thaum sib tsoo ntug.Yog li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them thaum tsim cov cuab yeej siv ntau cov hniav nyuaj.
Cov khoom siv vuam yuav tsum muaj qhov zoo wettability nrog ob qho tib si nyuaj alloy yog brazed thiab steel substrate.
Nws yuav tsum ua kom muaj zog txaus ntawm cov vuam ntawm ob chav tsev kub thiab qhov kub siab (raws li ob qho tib si cov cuab yeej siv tawv tawv thiab qee cov pwm muaj qhov sib txawv ntawm qhov kub thiab txias thaum siv).
Thaum ua kom ntseeg tau cov xwm txheej saum toj no, cov khoom siv vuam yuav tsum muaj qhov qis qis kom txo qis kev ntxhov siab, tiv thaiv cov kab nrib pleb, txhim kho brazing efficiency, thiab txhim kho kev ua haujlwm rau cov neeg ua haujlwm.
Cov khoom siv vuam yuav tsum ua kom pom qhov kub-kub thiab chav-kub plasticity kom txo qis kev ntxhov siab ntawm brazing.Nws yuav tsum muaj zoo flowability thiab permeability, nrog rau cov cuab yeej no yog ib qho tseem ceeb tshwj xeeb tshaj yog thaum brazing hard alloy multi- hniav txiav cov cuab yeej thiab loj hard alloy pwm pob qij txha.
Cov khoom siv vuam yuav tsum tsis txhob muaj cov ntsiab lus uas tsis tshua muaj evaporation, tiv thaiv cov evaporation ntawm cov khoom no thaum lub sij hawm brazing cua sov thiab cuam tshuam rau qhov zoo ntawm vuam.
Cov khoom siv vuam yuav tsum tsis txhob muaj cov khoom muaj txiaj ntsig, tsis tshua muaj hlau, lossis cov khoom ua rau tib neeg noj qab haus huv.
