Cov cub tawg brazing nqus tsevtab tom hloov pauv cov txheej txheem ntawm kev sib koom ua ke ntawm cov khoom siv hauv kev lag luam. Los ntawm kev tsim kom muaj ib puag ncig uas tswj tau zoo, cov cub tawg no muaj peev xwm tsim cov pob qij txha muaj zog ntawm cov khoom siv uas yuav nyuaj lossis tsis yooj yim sua kom sib koom ua ke siv cov txheej txheem ib txwm muaj.
Kev sib txhuam yog ib qho txheej txheem sib koom ua ke uas cuam tshuam nrog kev yaj cov hlau filler rau hauv qhov sib koom ua ke ntawm ob yam khoom siv hauv qab cua sov thiab, qee zaum, siab. Hauv kev sib txhuam nqus tsev, cov txheej txheem no ua tiav hauv huab cua nqus tsev lossis hydrogen kom tiv thaiv kev oxidation ntawm cov khoom siv sib koom ua ke thiab txhim kho qhov zoo ntawm qhov sib koom ua ke. Cov cub tawg nqus tsev ntxiv ib txheej ntxiv ntawm kev tswj hwm los ntawm kev tshem tawm cov khoom tsis huv thiab tswj cov pa roj nyob ib puag ncig cov khoom siv thaum lub sijhawm sib txhuam.
Cov txiaj ntsig ntawmcov cub tawg brazing nqus tsevmuaj ntau yam. Los ntawm kev tshem tawm huab cua thiab lwm yam tsis huv, cov chaw tsim khoom tuaj yeem tsim cov pob qij txha huv dua thiab muaj zog dua. Kev tswj hwm qhov kub thiab txias, siab, thiab huab cua kuj ua rau muaj kev sib txhuam zoo dua, ua rau kev sib koom ua ke zoo dua thiab sib xws. Tsis tas li ntawd, kev sib txhuam nqus tsev tuaj yeem siv los koom cov khoom sib txawv uas yuav nyuaj rau koom nrog siv cov txheej txheem ib txwm muaj.
Ntxiv rau cov txiaj ntsig no, cov cub tawg uas siv lub tshuab nqus tsev kuj tseem siv hluav taws xob tsawg, ua rau cov chaw tsim khoom txuag tau cov nqi tsim khoom. Cov thev naus laus zis kuj tseem muaj cov yam ntxwv kev nyab xeeb zoo dua, suav nrog kev tswj hwm tsis siv neeg thiab cov txheej txheem kev nyab xeeb uas ua rau hauv.
Zuag qhia tag nrho, thev naus laus zis ntawm lub tshuab nqus tsev yog ib qho kev txhim kho zoo siab hauv kev tshawb fawb txog cov ntaub ntawv. Raws li qhov kev thov rau cov pob qij txha zoo, muaj zog ntawm cov ntaub ntawv kev lag luam txuas ntxiv mus, cov chaw tsim khoom tuaj yeem cia siab rau cov chaw tsim khoom no los tsim cov pob qij txha meej tshaj plaws thiab sib xws. Los ntawm kev nqis peev hauv cov chaw tsim khoom nqus tsev, cov chaw tsim khoom tuaj yeem cia siab tias yuav zoo dua, siv hluav taws xob zoo, thiab txuag nqi hauv lawv cov txheej txheem tsim khoom.
