Lub sijhawm nws yuav siv sij hawm ua kom tiav Weld nrog Mig Welder sib txawv heev dua tshiab - los ntawm ob peb feeb rau cov sij hawm me me rau ib qho phiaj xwm loj. Tsis zoo li lo nplaum vuam, uas yuav tsum tau nres hloov cov electrodes, mig vuam cov hlau txuas txuas ua rau nws ua ib qho ntawm cov txheej txheem vuam ceev tshaj plaws. Txawm li cas los xij, qhov tseeb xws li qhov phiaj xwm loj, hlau tuab, sib koom ua ke, thiab qib kev txawj ua si txhua lub luag haujlwm hauv kev txiav txim siab tag nrho. Nkag siab cov kev hloov pauv no pab teeb tsa qhov kev cia siab tiag tiag, txawm hais tias koj tab tom txhim kho lub bracket tawg lossis ua rau tus ncej hlau.
Cov Ntsiab Lus Tseem Ceeb uas cuam tshuam rau kev siv lub sijhawm
1. Qhov project loj thiab weld ntev
Qhov pom tseeb tshaj plaws yog qhov ntev tag nrho ntawm Weld xav tau. Ib qho luv luv, sab npoo sib luag yuav siv sijhawm tsawg dua li ntev lossis sib koom ua ke.
Kho me me: A 1-2 nti Weld (piv txwv li, kho cov kab tawg lossis thaiv ib lub qhov hauv lub vaj huam sib luag steel) yuav siv sijhawm 10-30 feeb ntawm lub sijhawm vuam siv. Qhov no suav nrog kev tawm tsam Arc, tso cov hlaws, thiab cia cov weld txias me ntsis.
Cov Haujlwm Nruab Nrab: Vuam ib qho 20-nti ntawm lub tsheb thauj khoom lossis 1-ko taw square steel phaj (nrog ib tus lej) yuav siv 1-3 feeb. Yog tias muaj ntau tus dhau mus xav tau (tsim kom tuab), ntxiv 30 vib nas this mus rau 2 feeb toj ib zaug.
Cov haujlwm loj: Siv lub sijhawm 10-taw hlau 10-taw ntawm tag nrho Weld ntev) tuaj yeem siv sijhawm 15-30 feeb ntawm lub sijhawm vuam, tsis suav teeb tsa lossis tu.

2. Hlau tuab
Thicker hlau yuav tsum tau qeeb qeeb taug kev thiab ntau zaus ntau kis, nce tag nrho lub sijhawm.
Nyias Hlau (16-18 Galee): Mus ncig ua si nrawm nrawm (4-6 ntiv tes ib feeb) vim tias tsawg dua yog xav tau kom tsis txhob hlawv - los ntawm. Ib tug 12-nti sib xyaws yuav siv 2-3 feeb nrog ib tus lej.
Nruab nrab thickness (¼-⅜ nti): Mus ncig ua si nrawm rau 2-4 nti hauv ib feeb los xyuas kom meej tag nrho cov kev nkag mus. Ib tug neeg 12-nti yuav siv sijhawm li 3-6 feeb, thiab tej zaum yuav xav tau 2 kis kom muaj zog.
Tuab hlau (½ nti lossis ntau dua): Mus ncig ua si nrawm poob rau 1-2 nti ib feeb. Ib tug neeg 12-nti yuav siv tau 6-12 feeb rau thawj daim ntawv hla (hauv paus dhau), nrog 2-3 tus ntxiv ntxiv ntxiv 5-10 feeb txhua.
Piv txwv li, vuam ib ½ Ã - nti tuab rau kev txhim kho lub hauv paus weld, tom qab ntawd} tripling lub sij hawm ntawm ib tus lej ntawm nyias hlau.
3. Koom tes sib koom ua ke
Yooj yim sib koom tes (zoo li ncaj pob qij txha) nrawm rau weld tshaj cov nyom (xws li t} pob qij txha lossis nkhaus).
Ncaj, pob qij txha pob qij txha: Qhov yooj yim rau weld, nrog khov kho mus ncig ua si. Ib 10-nti ncaj leeg siv sijhawm li 2-5 feeb, nyob ntawm cov tuab.
T - pob qij txha lossis rooj sib koom ua ke: Xav tau ntau dua los ua kom meej fusion ntawm ob sab. Ib lub kaum 10-nti kaum weld yuav siv 3-7 feeb, raws li koj yuav ncua sij hawm yuav kho lub kaum sab xis lossis maj mam kom tsis txhob muaj kev txwv.
Nkhaus lossis tsis xwm yeem: Vuam ib puag ncig cov yeeb nkab los yog nkhaus bracket xav tau qeeb, ceev faj kev txav mus kom muaj kev sib tw loj. Ib tug 10-nti nkhaus ntawm ntug dej yuav siv tau 5-10 feeb.
Cov pob qij txha ua ke kuj tseem nce teeb lub sijhawm teeb tsa - clamping lub hlau los tuav txoj kab nkhaus lossis lub ntsej muag ua ntej pib siv vuam.
4. Welder kev txawj
Cov pib ntev dua li cov neeg muaj txiaj ntsig vim qeeb qeeb taug kev nrawm, nres ntau dua, thiab kev hloov kho.
Cov pib: Tej zaum yuav ncua sij hawm xyuas lub arc, kho cov chaw, lossis kho lawv lub kaum sab xis. Ib qho kev sib tw 12-nti uas siv sijhawm li 2 feeb tuaj yeem xaiv cov pib 5-7 feeb.
Intermediate Welders: Muaj peev xwm tswj cov kev taug kev mus ncig ua si tab sis yuav qeeb qeeb rau cov pob me me. Tib yam 12-nti ntug yuav siv 3 feeb.
Cov tub txawg: Weld nrog kev nrawm nrawm thiab kaum, txo nres. Lawv ua tiav 12-nti txoj phuam hauv 2-3 feeb, nrog cov txiaj ntsig huv si uas yuav tsum tsis txhob tu dua.
Xyaum pib muaj sijhawm ntau -}} Cov neeg pib txiav lawv lub sijhawm ua haujlwm hauv ib nrab tom qab ob peb hlis.
5. Teeb tsa thiab tu lub sijhawm
Vuam lub sij hawm tsis suav nrog prep ua haujlwm lossis tshaj tawm - Weld famns, uas tuaj yeem ntxiv sijhawm ntau dua li qhov siv vuam ntau dua li qhov siv vuam.
Teeb tsa: Ntxuav hlau (tshem cov xeb lossis xim), clamping lub chaw ua haujlwm yuav siv 5-20 feeb rau cov haujlwm me, thiab 30-60 feeb rau cov loj.
Kev ntxuav: Chipping slag (yog tias siv flux tseem ceeb), kev sib tsoo sib tsoo, lossis txhuam cov weld ntxiv 5-15 feeb. Rau kom zoo nkauj welds, sanding kom du cov hlaws tuaj yeem siv 10-30 feeb.
Rau kev kho me me (piv txwv li, ib 2 {- nti weld ntawm ib lub rusty bracket), thiab kev tu, tsuas yog 2% yog 2% yog vuam tiag tiag.
Yuav ua li cas kom ceev tau MIG VUAM (yam tsis muaj kev txau zoo)
Thaum qee yam (zoo li hlau tuab) yog tsau, koj tuaj yeem txo tag nrho lub sijhawm nrog cov lus qhia no.
Prep hlau ua ntej: Huv si thiab clamp workpieces ua ntej pib - Tsis txhob tsum kom tau zom xeb mid- Weld.
Siv cov xaim xaim thiab chaw: Ib tug 0.045-nti hlau tso cov hlau ntau dua 0.035-nti, nrawm nrawm ua tuab tuab hlau vuam. Match voltage thiab hlau pub khoom siv ceev ceev rau hlau tuab (siv koj lub tshuab daim duab) kom tsis txhob nres rau kev kho kom haum.
Weld hauv kev txiav txim siab: Rau cov thav ntawv lossis ntau {- Tshooj cov phiaj xwm ua ntej, ces tsiv mus rau fab ncaj nraim thawj zaug, tom qab ntawd hloov mus rau cov khoom siv ncaj qha rov ua dua} clamping thiab repositioning.
Xyaum Ua Si Ceev Xwm Txheej: Ib qho kev sib dhos (tsis dhau nrawm dua, tsis dhau dhau) kom dhau kev ua haujlwm dhau los ntawm kev tsis xws luag zoo li porosity lossis undercut.
{- Ntiaj Teb Cov Qauv Ntawm Mig Vuam Sijhawm
DIY PROJECT: VUAM AV HLAU CIB STEEF: Ib 6 {- nti ncaj weld ntawm ⅛-nti hlau. Teeb (huv, clamping) yuav siv 5 feeb; vuam siv 30 feeb; Kev tu tu li 2 feeb. Tag nrho: ~ 7.5 feeb.
Kho: Kho Lub Tsheb Tail Tailing Pob Khawm: Ib tug 3 {{- nti t} 2}} sib koom tes ntawm cov hlau ¼-¼-nti. Teeb (tshem cov xim, clamping) siv 10 feeb; 2 WELD kis tau 2 feeb tag nrho; Kev tu tu 5 feeb. Tag nrho: ~ 17 feeb.
Fabrication: Tsim 4-ko taw steel rooj ncej: 8 Taw ntawm tag nrho Weld Length (feem ntau cov nqeams ncaj) ntawm ⅜ - nti hlau. Teeb (txiav hlau, clamping) yuav siv 45 feeb; 3 hla ib leeg mus 25 feeb tag nrho; Kev tu tu li 15 feeb. Tag nrho: ~ 1 teev 25 feeb.

Lub sijhawm los rau Weld nrog mig welder li ntawm vib nas this rau kev kho me me kom teev rau cov sij hawm loj, tuab {} hlau tej yaam num. Lub sijhawm siv vuam nyob ntawm qhov project loj, hlau tuab, theem kev sib koom tes, thiab kev cob qhia nrog kev tu ncua ntev dua li qhov vuam nws tus kheej. Mig vuam lub nrawm nrawm dua nyob hauv nws cov xaim hlau nrag khoom noj, uas txo qis nres muab piv rau lwm cov txheej txheem.
Rau cov pib tshiab, tsom rau kev sib xws ntawm kev nrawm nrawm - rushing ua rau tsis xws luag uas yuav tsum tau ua haujlwm (thiab ntau lub sijhawm). Raws li koj tau txais kev txawj, koj yuav ua kom nrawm nrawm nrawm dua thaum ua kom zoo. Txawm hais tias koj tab tom daws kev kho kom sai lossis kev nkag siab loj, nkag siab cov sijhawm no pab koj npaj cov phiaj xwm thiab teem sijhawm tiag tiag.
