Kev nkag siab hauv flux tseem ceeb vuam - Koj tuaj yeem sib txig sib luag, tawm hauv Weld muaj kev tawg lossis sib cais nyob hauv qab. Qhov teeb meem ntxhov siab tab sis feem ntau kho, raws li nws feem ntau yog cov qauv xws li cov tswv yim cua sov, hlau pub nrawm, lossis txheej txheem. To taub cov hauv paus ua rau ntawm daim av ntiav yog qhov tseem ceeb rau kev kho koj cov txheej txheem thiab ua tiav qhov tob tob, muaj zog nkag siab zoo yog muaj peev xwm.
1. Cov lus qhia tsis txaus
Qhov kev ua rau muaj kev nkag rau hauv qhov tob tob tsis yog qhov kub txaus kom ncav lub hauv paus. Flux Core vuam nyob ntawm lub siab - kub arc kom yaj los ntawm lub hauv paus hlau lub ntsej muag thiab tsim lub cheeb tsam fusten. Yog tias cov lus tawm cua sov dhau dhau, cov arc tuaj yeem yaj cov hlau core, ua rau muaj weld ntiav uas tshaj li kev sib tham nrog nws.
Dab tsi ua rau cov lus sov tsawg dua?
Tsis muaj voltage lossis amperage: flux tseem ceeb vuam yuav tsum muaj voltage (los tswj arc tshav kub) thiab amperage (kom yaj (kom yaj). Yog tias koj lub tshuab tau teeb tsa qis dhau - Piv txwv, siv 150 amps {}} Lub arc tuab yuav tsis tsim kom muaj cua sov txaus.
Hlau pub ceev uas yog dhau nrawm heev: ib qho xaim pub ceev uas lub arc muaj peev xwm los tau "Dej nyab" chav weld. Cov hlau melts sai sai tab sis tsis hloov txaus cua sov mus rau lub hauv paus hlau, tsim ib qho ntiav hlau muag, weldy.
Tsis yog Hlau Hlau Hlau: Siv Hlau Uas Tsawg Me Me Rau Cov Hlau Hlau Themness Txwv Cov Lus Tawm Kub. Lub 0.035 - nti hlau, piv txwv li, tsis tuaj yeem tsim kom muaj cua sov txaus, txawm tias muaj qhov siab tshaj plaws.
Yuav kho nws li cas:
Kev nce voltage thiab amperage maj (xa mus rau koj lub tshuab daim ntawv qhia rau cov chaw pom zoo raws li cov hlau thuv thiab hlau taub).
Match Hlau Pub Ceev rau voltage: Kev pub nrawm dua yuav tsum muaj ntau dua voltage kom yaj cov xaim thiab hloov cua sov rau lub hauv paus hlau.
Siv cov hlau loj dua rau cov hlau tuab rau cov hlau tuab (piv txwv li, 0.045- nti hlau, 0.062-nti rau ½-nti).
2. Tsis muaj kev mus ncig ua si
Mus ncig ua si ceev - tus nqi uas koj txav lub vuam phom raws cov sib koom tes nrog kev nkag mus. Tsiv mus nrawm dua lub weld ntawm cov cua sov xav tau rau kev nkag mus qeeb, thaum txav mus qeeb tuaj yeem ua rau muaj teeb meem qeeb (tab sis qhov no tsis tshua muaj teeb meem).
Vim li cas txoj kev taug kev nrawm nrawm ua rau cov av ntiav welds:
Thaum koj tsiv tua phom sai heev, lub arc tsis nyob ntawm ib qho point ntev txaus kom yaj lub hauv paus hlau tob. Flux Core cov hlau me me thiab tso nyiaj, tab sis cov hlau hauv paus feem ntau tsis muaj tseeb, ua rau "txias" weld nrog tsawg kawg nkaus. Qhov no yog tshwj xeeb tshaj yog nyob rau hauv cov pib uas maj nrawm rau ua tiav weld lossis ntshai tsam hlawv los ntawm hlau hlau nyias.
Yuav kho nws li cas:
Qeeb koj txoj kev taug kev ncig mus qhia rau Arc tshav kub lub hauv paus hlau. Ib txoj cai zoo ntawm tus ntiv tes xoo yog khaws cia Weld Bead Dav Dav 2-3 zaug lub hauv paus dos (piv txwv li}} ntso hlau dav rau 0.045-nti hlau).
Xyaum rau ntawm cov ntawv sib txuas hlau kom pom cov PACE ruaj khov: Weld yuav tsum saib du thiab tsis muaj kev sib xws, nrog pom fust ntawm cov npoo uas nws ntsib cov hlau.
3. Phem phom lub kaum sab xis lossis arc ntev
Lub kaum sab xis ntawm koj rab phom welding thiab qhov kev ncua deb ntawm cov hlau hlau (arc ntev) tswj tau txais kev sib koom ua ke. Misalignment ntawm no tuaj yeem hloov pauv thaum tshav kub deb ntawm cov kav hlau, txo kev nkag mus.
Phom Lub Qub Zog:
Ib tug cab lub kaum ntse ntse (rub tawm ntawm tus weld) tuaj yeem tso cov cua sov rau cov twb tau tso cia weld hlau es tsis yog lub hauv paus hlau ua ntej, txwv tsis pub nkag.
Ib lub kaum ntse ntse (phom tiled (phom tilted rau pem hauv ntej ntau tshaj 15-20 degrees arc tshav kub, txo nws lub ntsiab lus rau hauv paus.
ARC Ntev Teeb Meem:
Ib qho dhau - luv luv ARC (xaim lub hau yuav luag kov cov hlau) tuaj yeem ua rau cov hlau ua kom sov, txo cov pas dej arc thiab tsim kom muaj weld ntiav.
Ib qho dhau - ARC (ntau dhau ntawm xaim thiab lub hauv paus hlau) tsis muaj zog ntawm arc muaj peev xwm nkag mus. Lub Weld kuj tseem yuav ntxeem tau los ntawm cov kev sib kis ntawm covmos.
Yuav kho nws li cas:
Siv lub laub me ntsis lub kaum (10-15 degrees rau pem hauv ntej) kom muaj cua sov ncaj qha rau hauv paus hlau thaum tswj lub arc ruaj khov.
Khaws arc ntev raws li flux tseem ceeb, arc ntev yuav tsum sib npaug ntawm cov hlau uas cov voos hlau (piv txwv li 0.245} nti hlau). Mloog rau lub "crackling" suab-suab "dhau heev ntsiag to (luv luv) lossis nrov dhau (ntev arc) qhia tias misalignment.
4. Kev paug los yog coated luj hlau
Flux tseem ceeb ntawm lub teeb xeb yog ntau dua mig vuam, tab sis cov pa paug vuam, tab sis cov pa hluav taws xob hnyav tuaj yeem ua raws li kev hloov pauv, thaiv kev hloov pauv thaum tshav kub.
Cov kab ke sib kis uas ua rau muaj Welds ntiav:
Tuab xeb los yog nplai: ib txheej tawv nqaij ntawm xeb insulates lub hauv paus hlau, tiv thaiv arc los ntawm melting los ntawm cov hlau huv. Tus weld yuav muab rau tus xeb tab sis tsis yog cov hlau hauv qab, tsim kom muaj zog, sib koom ua ke ntiav.
Roj, pleev xim, lossis cov tshuaj tiv thaiv: cov tshuaj no hlawv tawm thaum rhuab, tsim cov roj hnab ris uas cuam tshuam rau arc thiab txo cov tswv yim kom sov rau lub hauv paus hlau.
Galvanized Txheej:
Yuav kho nws li cas:
Ntxuav lub hauv paus hlau ua kom huv nrog cov hlau txhuam, sib tsoo, lossis khau khiab kom tshem tawm xeb, nplai, lossis pleev xim. Taw rau kev ci ntsa iab, liab qab hlau raws cov kab sib koom ua ke.
Rau galvanized steel, zom tawm ntawm zinc txheej 1-2 nti los ntawm thaj chaw weld, lossis siv tshwj xeeb flux tseem ceeb tsim rau galvanized hlau (piv txwv li E71T-11G) uas TAG TIV ZINC VAPOR.
5. Tsis yog xaim hom lossis flux tsim
Tsis yog tag nrho cov xov hlau tseem raug tsim los rau kev nkag mus tob. Kev siv hlau tsim rau tsawg - Cov tshuaj kub lossis cov hlau me me tuaj yeem txwv tsis pub koj lub peev xwm kom ua tiav cov chaw kom haum.
Hom Ntaus Hlau Ntaus:
Me - txoj kab uas hla ntawm cov hlau tuab, cov hlau roj hmab ua ntej, tsis hais cov hlau.
Tsawg -} kev nkag siab flux formulations: qee cov xov hlau verds lossis nyias cov ntawv sau rau kev nkag mus, ua rau lawv tsis haum cov txheej txheem sib koom tes.
Yuav kho nws li cas:
Xaiv cov xov hlau sau rau "sib zog nqus" lossis "kev siv" (piv txwv li} 8} {} { Cov xaim no muaj cov tshuaj flux uas txhim kho arc tsom thiab kev hloov cua sov.
Phim xaim lub taub rau hlau tuab: 0.045- nti rau ¼ {4 {} nti hlau; 0.062 {- nti rau ¼-nti rau ½-nti hlau.
6. Siv lub tshuab lossis khoom siv
Txawm hais tias nrog cov txheej txheem tsim nyog, cov khoom siv khoom siv tuaj yeem txwv cov tswv yim kub thiab nkag mus. Cov teeb meem no tsis tshua pom tseeb tab sis tseem ceeb rau chaw nyob.
Cov khoom siv cov txuj ci txawv:
Cov lus qias neeg los yog hnav cov lus tiv thaiv: ib qho kev sib cuag lossis kev sib tiv tauj hluav taws xob txwv thiab cuam tshuam hluav taws xob tam sim no, ua rau muaj kev cuam tshuam arc cua sov thiab mob taub hau.
Kev xoob xoob: Kev sib txuas hluav taws xob tsis zoo (piv txwv li, ntawm rab phom thiab tshuab) tsim kev tiv thaiv, txo qis thiab cov khoom tawm cua sov.
Tshuab underpowered: me me 110V flux flux flux flux flux flux flue {{v caag {1} - nti thiab tuab.
Yuav kho nws li cas:
Hloov cov lus qhia kev sib cuag tsis tu ncua (txhua 8-10 teev ntawm vuam) kom ntseeg tau hlau cov hlau pub thiab muaj kev sib xws.
Txheeb xyuas txhua qhov sib txuas rau nruj nreem, thiab huv cov kev txwv kom tshem tawm corrosion.
Siv lub tshuab nrog cov zis txaus: nrhiav yam tsawg kawg 200-amp tshuab rau cov qauv flux core vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vuam vacding ntawm cov hlau tuab.
Kuaj thiab daws teeb meem
Yuav kom kuaj qhov nkag mus, sim ua qhov ntsuas yooj yim: Weld ib lub hlaws dai ntawm ib daim ntawm tib cov hlau tuab koj ua haujlwm nrog. Tom qab txias, nti tawm ntawmSlag thiab soj ntsuam weld:
Weld ntiav ntiav yuav muaj ib txoj kab fusion nyias, nrog pom me ntsis ntawm cov hlau weld ntawm weld hlau thiab cov hlau hlau.
Tus Weld zoo yuav qhia qhov txawv "Fusion Done" uas cov hauv paus hlau tau yaj thiab sib txuas nrog cov hlau tuab (100% rau cov pob qij txha hlau).
Yog tias qhov kev ntsuas Weld tseem yog ntiav, kho ib qho sib txawv ntawm ib lub sijhawm (piv txwv, nce voltage, qeeb taug kev nrawm) thiab sim dua. Txoj kev no ntawm kev tshem tawm yuav pab koj cais tawm qhov ua kom.
