Txoj kev tsim lub tshuab ua lub ntsej muag muaj kev sib raug zoo thiab ua haujlwm nrog vuam thev naus laus zis. Lub tshuab thev naus laus zis tshuab feem ntau yog siv hauv kab ntau lawm. Nws tuaj yeem hno cov ntim sab nraud ntawm cov khoom raws li cov qauv coj ua. Cov moulding tshuab yog ib qho kev teeb tsa ua ke thiab cov khoom siv hauv kev lag luam moulding tshuab kev lag luam, thiab cov vuam nyhuv tuaj yeem khaws cov qauv ntawm cov cuab yeej siv nyob hauv lub xeev kom ruaj khov. Ntxiv mus, nws tseem tuaj yeem ua rau kev ua haujlwm ntawm cov khoom siv tau muab coj los ua raws li cov khoom lag luam nrog cov khoom lag luam zoo. Yog li dab tsi yog qhov cuam tshuam thiab cuam tshuam ntawm vuam thev naus laus zis ntawm kev siv tshuab?
Vuam yog tus txheej txheem uas nquag siv, uas tuaj yeem siv tau tsis hais txog ntawm cov khoom siv. Qhov 2d tshuab moulding feem ntau yog tsom cov khoom lag luam yas, yog li vuam txoj kev muaj ntau yam yuav tsum tau ua nrog lub tshuab moulding.
Muaj ntau lub zog siv rau cov vuam siv niaj hnub, suav nrog cov nplaim hluav taws xob, hluav taws xob arc, laser, cov nqaj hlau hluav taws xob, kev sib txhuam, thiab ultrasonic. Ntxiv rau qhov siv rau hauv cov chaw lag luam, vuam kuj tuaj yeem nqa tawm hauv ntau qhov chaw ib puag ncig, xws li lub tshav pob, hauv qab dej thiab chaw. Txawm hais tias nws nyob qhov twg, vuam tuaj yeem coj kev phom sij rau tus neeg teb xov tooj, yog li tsim nyog tiv thaiv kev tiv thaiv thaum vuam. Qhov teeb meem tshwm sim los ntawm vuam mus rau tib neeg lub cev muaj xws li kub hnyiab, hluav taws xob, qhov muag tsis pom kev, nqus tau cov pa roj lom, thiab muaj hluav taws xob ntau dhau. Thaum lub sijhawm kev siv vuam, yog tias cov huab cua nyob hauv kev sib cuag ncaj qha nrog lub siab kub pas dej ntxuav tawm, cov pa oxygen hauv cov cua yuav oxidize hlau thiab ntau cov ntsiab lus tsis haum. Nitrogen thiab dej nyob rau hauv cov cua nkag mus rau lub pas dej molten, thiab tseem yuav ua qhov pores, slag suav, kab nrib pleb thiab lwm yam tsis xws luag hauv qhov txuas thaum lub sijhawm tom qab txias, uas yuav tsis zoo thiab kev ua haujlwm ntawm lub weld. Cov yam ntxwv ntawm ntau lub zog vuam txoj kev yog tias lub siab raug thov thaum lub sijhawm vuam tsis siv cov khoom muab tub lim. Feem ntau lub siab vuam txoj kev, xws li diffusion vuam, vuam ntau zaus, vuam siab vuam, thiab lwm yam, tsis muaj txheej txheem melting, yog li tsis muaj teeb meem zoo li fusion vuam, uas muaj txiaj ntsig alloying cov ntsiab lus hlawv thiab cov ntsiab lus phem nkag mus rau hauv lub weld , yog li yooj yim vuam txheej txheem. Nws tseem txhim kho vuam kev nyab xeeb thiab kev noj qab haus huv.
