Cov nroj thiab tsob ntoo yog cov chaw tseem ceeb hauv qhov chaw xaiv qhov chaw ntawm qhov chaw. Thaum lub sij hawm kev tshawb fawb daim teb, yam cuam tshuam nrog kev ruaj ntseg tag nrho ntawm lub qhov yuav tsum tsis tshwm sim thiab tshwm sim. Kev xaiv ntawm qhov chaw hlau yog tseem tshwj xeeb heev, thiab tseem muaj qee cov hauv paus ntsiab lus uas yuav tsum tau them nyiaj rau hauv kev ua haujlwm tsim kev tsim kho.
Muaj ob peb lub ntsiab lus kom them sai sai thaum siv vuam qhov hlau txhawb nqa:
1. Nyob rau hauv ib puag ncig huab cua, Welded steel txhawb nqa tau tuaj yeem tsim ib qho chaw mos. Ceevfaj tsis tau los nag thiab daus ntawm Weld.
2. Nyob rau lub caij ntuj no txias, yog tias lub phaj steel yog ntau tshaj 9 hli, nws tuaj yeem muab welded hauv ob peb txheej. Qhov no yog txhawm rau tiv thaiv qhov ntsuas kub ntawm kev ua qis dhau, tab sis feem ntau, vuam yuav tsum ua tiav rau ib zaug thiab txuas ntxiv. Thaum vuam, qhov tsis xws luag sab laug los ntawm kev siv vuam yuav tsum tau ntxuav ua ntej, thiab cov vuam txuas ntxiv tom qab tsis muaj teeb meem.
3. Hauv qhov chaw kub tsawg, cov hluav taws xob thiab cov xov hluav taws xob siv hluav taws xob tsawg dua thiab cov txiaj ntsig zoo hauv qab cov qauv.
4. Lub ntsej muag vuam siv rau vuam hauv qab xoom degrees, uas yuav tsum tau muab tso rau hauv lub thawv ci ntawm 80 mus rau 100 degrees Celsius, thiab siv thaum xav tau. Yog tias cov electrode tau muab tso rau hauv qab xoom ntau tshaj li ob teev, nws yuav tsum tau rov qab rov qab, tab sis tus naj npawb ntawm lub sijhawm yuav tsum tsawg dua peb zaug.
