Flux - Core Arc Vuam (FCAW) yog ib qho kev sib txuas ua ke ntawm cov ntaub thaiv hlau arc vuam (smaw) thiab roj roj arc vuam (GMAW). Nws yog qhov muaj nuj nqis rau nws tus nqi xa nqi siab, hloov tau rau cov neeg sab nraum zoov, thiab muaj peev xwm rau weld tuab cov ntaub ntawv zoo. Tsis zoo li ib txwm mig vuam, uas muab tso rau sab nraud tiv thaiv roj, Follment siv cov khoom siv wold tau sau cov khoom siv vuam thiab cov duab ntawm Weld hlaws. Qhov kev tsim qauv tshwj xeeb no ua rau nws xaiv tau hauv kev tsim kho, kev tsim qauv, thiab kho ua haujlwm.
Yuav ua li cas flux - tus tseem ceeb arc vuam ua haujlwm
Ntawm nws cov tub ntxhais, FCAW kev ua haujlwm los ntawm kev tsim hluav taws xob arc ntawm ib qho kev tsis tu ncua pub flux - Cored hlau thiab cov hlau hauv paus. Lub arc melts ob lub xaim (uas ua raws li ob tus tsiaj ua haujlwm thiab flux) thiab sib tw ntawm cov pas dej weld mold. Raws li cov xov hlau yaj, flux sab hauv nws tau tso tawm rau hauv pas dej, qhov chaw nws ua peb lub luag haujlwm tseem ceeb:
Tiv thaiv: flux vaporizes thiab ua cov roj huab ncig lub pas dej weld, tiv thaiv nws los ntawm cov pa taws nyiam cov pa thiab nitrogen. Cov roj av no yuav txwv tsis pub ua rau porosity, kab nrib pleb, lossis britleness hauv weld.
Deagidation: flux muaj cov ntsiab lus xws li silicon thiab manganese uas hnov mob nrog impurities (xws li oxides) hauv molting hlau, tshem lawv thiab huv weld.
SLAG Tsim: ib feem ntawm flux sololifies mus rau hauv cov txheej tiv thaiv cov txheej ntawm weld thaum nws txias. Qhov kev txhuam hniav rau sab sauv tawg kom tiv thaiv kev tawg, mus ua cov kab mob Weld hlaws rau hauv qhov du, tsis sib xws. Tom qab vuam, lub shell yog cab mus deb los qhia tau cov thawj coj ua tiav.
Cov txheej txheem tau siv ua ke nyob rau hauv cov nqe lus ntawm cov kav hlau pub {0} Zoo ib yam li Mig vuam thaiv (lossis txo cov khoom siv sib dhos thiab nthuav dav lossis thaj chaw sab nraum zoov.
Hom flux - tus tseem ceeb arc vuam
FCAW tau muab faib ua ob pawg tseem ceeb raws li kev tiv thaiv roj ntxiv. Txhua hom muaj qhov zoo thiab cov ntawv thov:

Hom no yog qhov zoo tagnrho rau:
Sab nraum zoov lossis chaw deb ua haujlwm (piv txwv li, cov chaw tsim khoom siv vuam, cov chaw tsim kho) qhov chaw cua yuav rho tawm cov roj.
Cov ntawv thov Portable, raws li nws tshem tawm qhov yuav tsum tau thauj cov roj hliav roj kheej.

Qhov zoo ntawm flux glux - tus tseem ceeb arc vuam
FCAW muaj ob peb cov txiaj ntsig tseem ceeb uas ua rau nws staple hauv ntau qhov kev lag luam:
Cov nqi xa nqi siab: Kev siv hlau txuas ntxiv tso cai rau FCAW kom tso nyiaj ntau weld hlau ib feeb dua smuam (pas vuam). Qhov no ua rau nws sai dua rau cov phiaj xwm loj, xws li Vuam tsheb thav ntawv txheej lossis Choj Cheebtsam.
Kev sib sib zog nqus yuam: FCAW tsim cov khoom muaj zog uas tob rau hauv lub hauv paus hlau, ua rau nws haum rau cov ntaub ntawv tuab hauv pob qij txha.
Versatility hauv txoj haujlwm: nws ua haujlwm tau zoo nyob rau hauv txhua qhov chaw vuam (tiaj tus, kab rov tav, ua haujlwm sib dhos, ib qho kev sib txuas ua ke,
Txo ua ntej ua ntej -}}} Cov flux lub zog tsis txaus ntseeg
Tus nqi efficiency: thaum flux - Cored hlau yog kim dua li cov khoom siv me me (vim yog qhov nrawm dua) thiab, hauv tus nqi nrawm, tshem tawm cov nqi roj, tshem tawm cov nqi roj.
Kev txwv ntawm flux - tus tseem ceeb arc vuam
Txawm hais tias nws cov txiaj ntsig, FCAW muaj kev txwv los txiav txim siab:
Kev tshem tawm Slag: Lub sleag txheej yuav tsum tau chipping los yog sib tsoo tom qab vuam, ntxiv ib qib ruam tsis xav tau nyob rau hauv roj {}}} tsuas yog mig vuam. Qhov no tuaj yeem yog lub sijhawm - noj mov rau me me, zoo nkauj wels.
Haus luam yeeb thiab cov pa taws: flux tsim cov pa luam yeeb ntau dua li mig vuam, yuav tsum tau ua kom zoo nkauj (piv txwv li cov tshuaj tua kab mob) los tiv thaiv cov tsiaj txhu los ntawm cov kab mob welders los ntawm cov phom sij.
Sib txig: tus kheej {{0} {} {shielded fcaw tsim tsim cov khoom siv hlau tseem ceeb uas yog cov post- Weld tu.
Tsuas yog precision rau cov ntaub ntawv nyias nyias: FCAW cov lus qhia sov ua rau nws haum kom haum rau cov hlau me me (hauv qab 16 kawg li cas)}}} los ntawm.
Cov khoom siv rau flux - tus tseem ceeb arc vuam
Cov cuab yeej FCAW tau zoo ib yam li Mig vuam teeb tsa tab sis yoog rau flux - cored hlau:
Lub Hwj Chim Source: ib qho tsis tu ncua - voltage (cv) welding tam sim no muab cov khoom ruaj khov thiab voltage, tseem ceeb rau kev tswj hwm ib qho arc nrog cov xaim hlau txuas nrog.
Hlau Feeder: Ib Pawg Neeg Tsav Tsheb Pub Flux - Cored hlau los ntawm kev sib tw sib tsoo (ntsuas hauv nti ib feeb).
Vuam rab phom: Tsim los kov flux - Cored hlau, nrog tus txhais pib / nres Arc thiab Hlau Pub. Phom rau tus kheej - shield fcaw yog yooj yim dua, thaum roj av- shielded versions suav nrog roj nozzle.
Flux -} cored hlau: muaj nyob rau hauv ntau yam diameters (0.035 nti rau 5/64 nti) thiab kev sib xyaw ua ke kom phim cov hlau (hlau, hlau stainless, thiab lwm yam).
Kev thaiv cov roj kheej kheej kheej (rau FCAW - g): txuas nrog cov kav hlau pub dawb los ntawm kev tswj hwm thiab hose, xa cov roj mus rau rab phom nozzle.
Cov Kev Siv Cov Khoom Siv Ntawm Flux - tus tseem ceeb arc vuam
FCaw yog siv thoob plaws kev lag luam rau nws qhov nrawm, lub zog, thiab kev yoog tau:
Txheej txheem steelrication: vuam kuv {{{{{l} nqaij nqaj, thiab tsheb nqaj hlau, thiab chaw ua haujlwm} 2} {shielded fcaw rau kev ua haujlwm sab nraum zoov.
Cov cuab yeej hnyav: txhim kho tsheb nrau av, thiab cov tsheb laij teb tsheb laij teb, ntaus pob tuab thiab portability yog qhov tseem ceeb.
Pipeline vuam: koom nrog ntu ntawm cov roj, roj, lossis dej pipelines hauv cov chaw taws teeb, siv tus kheej} daim hlau thaiv cov hlau kom tiv thaiv cua thiab huab cua.
Automotive thiab tsheb lag luam: nthuav tawm cov txaj, cov thav duab trailer, thiab cov charassis nrog roj av - Welds Welds.
Lub nkoj nkoj thiab cov khoom siv sib txuas ntawm cov nkoj thiab cov nkoj, qhov twg FCAW tus nqi tshaj tawm cov kev coj ua haujlwm loj ntawm kev ua haujlwm tau zoo.
Cov lus qhia rau kev vam meej flux - tus tseem ceeb arc vuam
Yuav kom ua tiav cov txiaj ntsig zoo nrog FCAW, khaws cov kev coj ua zoo tshaj plaws hauv siab:
Xaiv cov xaim xaim zoo: phim cov hlau rau lub hauv paus hlau (piv txwv li, siv cov hlau stainless hlau rau sab nraud, roj av {3} {} shielded rau precision).
Kho cov hlau pub ceev thiab voltage: cov tsis tswj no arc ntev thiab nkag mus. Siab dhau qhov pub ceev yuav ua rau "Buzzy" arc thiab ntau dhau lawm; Tsawg heev yuav ua rau tsis tiav fusion fusion.
Tswj kev mus ncig ua si sai sai: ib qho PACE ruaj khov ua kom zoo nkauj qau loj thiab nkag mus. Qeeb maj nrawm tuaj yeem ua rau hlawv -} los ntawm hauv cov hlau nyias, thaum lub sij hawm nrawm nrawm yuav tawm ntawm qhov khoob.
Tswj Phom Lub Qub: Lub 10-15℃thawb lub kaum sab xis (rab phom tilted rau pem hauv ntej) ua haujlwm rau feem ntau cov ntawv thov, coj tus ard rau hauv weld pas thiab txo lub ntsej muag.
Huv si sloag sai sai: tshem tawm slag thaum lub weld tseem sov (tab sis txias txaus kom tsis txhob chipping tawm ntawm weld nws tus kheej.
