Dab tsi yog vuam hlau siv rau?

Nyob rau hauv lub ntiaj teb ntawm kev ua haujlwm hlau thiab kev tsim khoom, vuam hlau ua si lub cev tseem ceeb. Nws yog ib qho tseem ceeb hauv kev siv hauv ntau cov txheej txheem vuam, ua rau koom nrog cov hlau sib txuas nrog lub zog thiab qhov tseeb.
Cov Ntsiab Lus Hauv Vuam Hlau
Vuam cov hlau pab ua cov khoom siv ua rau hauv cov txheej txheem vuam. Thaum kub tau thov, lub vuam hlau melts thiab fuses nrog lub hauv paus hlau, tsim kev sib raug zoo. Nws los nyob rau ntau hom, txhua tus tsim rau cov ntawv thov tshwj xeeb thiab txoj kev vuam.
Hom Vuam Hlau
1.Solid vuam hlau: qhov no yog ib hom feem ntau. Cov xov hlau cov khoom lag luam feem ntau ua los ntawm cov hlau cov hlau xws li hlau, hlau stainless, lossis txhuas. Lawv tau siv dav hauv roj Roj Hlau Arc Vuam (GMAW), tseem hu ua MIG (hlau inert roj) vuam. Hauv MIG vuam, cov hlau ruaj khov yog pub los txuas ntxiv ntawm cov hlau thiab cov hlau ua haujlwm melts cov hlau thiab cov hlau sib tw, tso cai rau lawv kom huse ua ke. Cov xov hlau tau muab cov nqi tso nyiaj siab thiab haum rau vuam ntau cov hlau, uas yog qhov siab} nrawm vuam thiab siab}} panels thiab cov lauj kaub lub cev.
2.flux -} cored vuam hlau: flux - cored hlau muaj cov qauv tubular muaj kev sib txawv thiab lwm yam ntxiv. Muaj ob lub ntsiab lus tseem ceeb: roj {{{{{}} shielded thiab tus kheej {5} {shielded. Roj - shielded flux {{8} Cov xov hlau cored yog siv hauv cov ntawv thov ntawm cov huab cua xav tau. Cov roj av sab nraud, feem ntau sib tov ntawm argon thiab carbon dioxide, pab tiv thaiv oxidation thiab porosity hauv weld. Cov hlau no siv tau siv rau kev siv vuam loj - teev steel qauv qauv zoo li choj thiab vaj tse. Tus kheej- shielded flux - Cored xov hlau, ntawm qhov tod tes, tsis tas yuav muab cov roj thaiv npog sab nraud. Lawv tau tsim los siv rau hauv ib puag ncig sab nraum zoov lossis cua hlob uas tej zaum nws yuav nyuaj rau kev tuav cov pa hluav taws xob kom zoo. Nyob rau hauv cov roj thiab roj kev lag luam, tus kheej {17} {} {18} Kuv tuaj yeem muab cov khoom siv vuam zoo nkauj hauv cov chaw sib tw.
3.Qu {-} cored vuam hlau: hlau} {} Cored xov hlau tab sis muaj puv nrog flux. Lawv muab cov txiaj ntsig zoo xws li tus nqi tso nyiaj siab thiab ua kom zoo Arc ruaj khov. Hlau - Cov xov hlau cored feem ntau siv nyob rau hauv cov ntawv thov uas yog qhov tseem ceeb yog qhov tseem ceeb ntawm {}}} khoom tsim. Piv txwv li, hauv kev tsim cov nrau av thiab cranes, hlau- cored wiret tuaj yeem sai thiab pab txo lub sijhawm thiab cov nqi.
Cov ntawv thov hla kev lag luam
1.Asomotive kev lag luam: vuam hlau yog qhov siv ntau yam hauv kev raug tshuaj lag luam. Nyob rau hauv lub rooj sib txoos ntawm lub tsheb lub cev, khoom siv vuam hlau tau siv hauv cov tshuab raj Mig welding tshuab. Cov kab ke no tuaj yeem ua tiav siab - ceev, kho cov qauv txheej txheem ntawm lub tsheb. Piv txwv li, cov chassis ntawm lub tsheb, uas yuav tsum muaj zog txaus kom tiv taus ntau tsav tsheb, yog welded siv cov xov hlau khoom siv. Vuam hlau kuj tau siv rau ntawm cov cav txheej txheem, xws li cov tog cav, qhov uas muaj peev xwm tsim muaj zog, xau}} Ua pov thawj txhaj tshuaj yog qhov tseem ceeb.
2.Cov kev lag luam: Hauv kev tsim kho, vuam hlau yog siv rau ntau cov ntawv thov. Cov qauv hlau, xws li skyscrapers steel, txuas hniav, thiab vaj tse vaj tse, cia siab rau vuam hlau rau koom nrog Hlau Beams thiab kab ntawv. Flux -} cored xov hlau, ob leeg roj {{4} {{5} {{5} {shielded, yog feem ntau siv. Roj - shielded flux - cored xov hlau yog nyiam rau cov chaw tsim khoom lossis muaj kev tiv thaiv helds nrog cov tsos. Self - shielded flux- Cov xov hlau ua kom zoo, raws li lawv tuaj yeem ua tau zoo yam tsis muaj kev xav tau roj av tas li.
3.Aerospace kev lag luam: Aerospace kev lag luam xav tau qhov zoo tshaj plaws vuam los xyuas kom muaj kev nyab xeeb thiab ntseeg tau ntawm cov dav hlau thiab lub dav hlau. Vuam hlau siv nyob rau hauv no yuav tsum ua kom tau raws cov qauv nruj. Tungsten Inert Roj (Tig) Vuam, feem ntau nrog kev sib tw vuam feem ntau xws li cov dav hlau cav, cov roj tso tsheb hlau, thiab airframe qauv. Qhov precision thiab kev huv ntawm Tig vuam, nrog rau kev siv Welds- Lub zog vuam, muaj peev xwm paub txog cov kev siv siab tshaj plaws thiab cov kev thov kev paub hauv kev siv hluav taws xob.
4.ManUacturing thiab Fabrication: Hauv kev tsim khoom dav dav thiab cov ntaub thaiv npog, vuam hlau yog siv los tsim ntau yam khoom. Los ntawm cov hlau me me rau cov tshuab loj, cov hlau vuam ua rau cov sib dhos ntawm cov chaw. Piv txwv li, hauv kev tsim cov khoom siv hauv tsev neeg thiab ntxhua khaub ncaws, vuam hlau, siv hlau vuam siv los koom nrog cov hlau panels thiab cov khoom siv. Hauv kev lag luam machinery manufacturing, xws li kev tsim cov conveyor tshuab thiab tshuab cov cuab yeej siv vuam siv los ua kom muaj zog thiab ruaj khov qauv.
Hauv kev xaus, Vuam hlau yog qhov tsis tseem ceeb hauv kev siv vuam, nrog cov ntawv thov hla ntau yam kev lag luam. Nws lub peev xwm los tsim cov kev sib tw muaj zog, txhim khu kev qha txhim kho ntawm cov hlau sib txawv ua rau nws lub pob zeb sib raug zoo thiab kev tsim kho. Raws li thev naus laus zis tseem ua ntej, kev txhim kho cov xov hlau vuam yuav ntxiv txhim kho cov kev ua tau zoo thiab qhov zoo ntawm vuam ua haujlwm hauv ntau thaj teb.
