Koj puas tuaj yeem weld stainless hlau nrog Mig Welder

Yog lawm, koj tuaj yeem tshoov weld stainless hlau nrog Mig Welder. Qhov tseeb, MIG (hlau inert roj) vuam yog ib txoj kev siv dav dav thiab muaj txiaj ntsig, thiab muaj peev xwm tsim muaj zog, corrosion {1} {reawant welds. Nws tau ua haujlwm thoob plaws kev lag luam xws li kev ua khoom noj, kev kho mob kho mob, thiab ua pov thawj kev ntseeg tau rau kev ua haujlwm thiab kev ua kom zoo nkauj.

Khoom Teeb Khoom

Tus qauv mig welder tuaj yeem coj tus hlau tsis muaj zog, tab sis nws yuav tsum tau teeb tsa zoo. Tsis zoo li cov hlau me me mig vuam, uas tuaj yeem siv cov tshuab tshiab, stainless hlau tau txais txiaj ntsig los ntawm kev hloov voltage nrog cov khoom siv hluav taws xob kom zoo rau lub arc. Ntau cov neeg tua tsiaj niaj hnub no suav nrog "stainless hlau" presets, tab sis txawm tias nkag {}} Cov qauv hloov ua haujlwm nrog kev kho cov qauv.

Cov hlau pub mis yog qhov tseem ceeb. Stainless hlau vuam xaim yog qhov nyuaj dua li cov me me hlau xaim tab sis softer dua li alieces {1} Ib daim ntawv loj tsim rau cov hlau tsis muaj hlau (TEFLON lossis nylon) txo kev sib txhuam, zam kev jams uas cuam tshuam rau arc.

Muab xaim xaim thiab thaiv cov roj

Xaiv txoj cai ua tub xaim xaim yog qhov tseem ceeb kom phim stainless hlau yog corrosion tsis kam. Cov kev xaiv ntau tshaj plaws yog:

• 308L: Tau tshaj 304 stainless hlau (lub feem ntau cov qauv siv tau siv), muab cov khoom siv corrosion zoo tshaj plaws thiab kev sib tw. Tus "l" txhais tau cov pa roj carbon qis, uas tiv thaiv carbide nag lossis qhov teeb meem uas tsis muaj zog wels hauv he- chaw ib puag ncig).
• 316L: Siv rau 316 stainless hlau (tiv taus ntsev thiab tshuaj), zoo tagnrho rau cov kev siv tubrog nkoj lossis kev lag luam.

Cov kab sib txuas hlau yog nyob ntawm cov khoom tuab: 0.030-nti rau nyias ntawv (16 teev tshuaj ntsuab) thiab 0.045-nti rau cov khoom siv thicker (1/8-nti lossis ntau dua).

Kev thaiv cov roj tsis yog - sib ceg rau cov hlau stainless. Tsis zoo li cov hlau me (uas siv Argon - roj carbon dioxide mixes), stainless hlau yuav tsum muaj roj thiab nitrogen kom tsis txhob muaj kev tiv thaiv thiab porosity. The go-to choice is 98% argon + 2% oxygen-it stabilizes the arc, produces a smooth bead, and minimizes spatter. Rau cov khoom siv thicker lossis ntau dua qhov tseeb, ib qho tri {{9} mix (argon, helces sib xyaw (muaj txiaj ntsig kom tsis txhob ua warping.

Base Hlau Npaj

Stainless cov hlau loj tshaj plaws yog paug. Roj, av, los yog txawm lw hlau los ntawm cov cuab yeej hlau tuaj yeem ua rau muaj xeb lossis tsis muaj zog. Los npaj:

• Ntxuav cov nplaim dej: so nrog acetone lossis tus kav hlau stainless tsev ntxhua khaub ncaws tshem roj, roj, lossis ntiv tes.
• Tshem tawm Oxides: Siv cov hlau uas muaj siab dhau los txhuam (tsis txhob siv cov hlau me me) kom txhuam kom txhuam cov roj oxides, uas muaj peev xwm txuas cov roj hauv Weld.
• Haum nruj me ntsis: khoob ntawm cov yuav tsum yog 0.010-0.020 nti kom paub meej tias muaj cua sov ntau heev. Rau tuab stainless hlau (1/4-nti +), bevel sawv mus rau 30-45℃rau tag nrho cov kev nkag mus.

Kev Tswj Cua Sov

Stainless hlau ua tshav kub qeeb qeeb dua li cov hlau me me, yog li nws khaws cov khoom siv kub ntev dua}}} cim (xiav / dub cim) yog overheated. Yuav kom tsis txhob muaj no:

• Siv cov cua sov qis dua li cov hlau me me ntawm tib tuab. Piv txwv li, 1/8-nti 304 stainless 30-200 amps, vs. 180}}}}}}}}}}} - - 220 amps rau cov hlau me me.
• WELD hauv kev tawg ntho hauv luv, nres kom cia cov hlau txias yog tias nws hloov xiav. Ib tug "straw kub" xim qhia tau cov cua sov zoo tshaj plaws; Kev tsaus ntuj hu ua kev kub ntxhov heev.
• Taug kev ntawm tus neeg nyob ruaj khov, muaj qhov nrawm. Qeeb dhau, thiab cua sov ua; Kev nrawm heev, thiab Weld Luj Fusion Fusion.

Arc thiab Taus mom

Tswj luv luv, ruaj khov arc (1 / 8-1 / 4 nti) kom pom tseeb thaum tshav kub kub thiab tiv thaiv lub pas dej weld. A ARC ntev kos rau saum huab cua, ua rau porosity. Tuav lub teeb rau ntawm 10-15℃thawb lub kaum sab xis (deb ntawm Weld kev taw qhia) kom tawg oxides thiab txhim kho kev pom kev.

SYNC Hlau Pub Ceev Kub Nrog Voltage: Ib tug du "Buzzing" Arc txhais tau tias chaw teeb tsa. Yog tias cov hlau stutters lossis arc sputters, kho cov hlau pub kom ceev lossis qis dua los ntawm 5-10% thiab ntsuas ntawm cov ntawv sib txuas.

Post - Weld Saib Xyuas

Cov hlau stainless hlau yog ib txwm corrosion - tiv taus, tab sis ncej}} weld tu Enhees durability:

Siv tus hlau stainless hlau txhuam (mob siab rau cov khoom siv) kom tshem tawm slag thiab sab thaum cov hlau tseem sov.

Rau qhov tseem ceeb (zoo li zaub mov - Cov khoom siv qib vol) Cov kauj ruam no yog xaiv rau tsis yog- tseem ceeb siv tab sis pom zoo rau sab nraum zoov lossis siab} noo noo puag ncig.

Mig vuam stainless hlau Nws tseem yog ntau tus pib-}}}}}} Tus phooj ywg sib txuas lus, raws li cov kav hlau txuas ntxiv txo cov tes sib txuas ua ke. Thaum ua tiav txoj cai, Mig Welds phim lub hauv paus hlau lub zog thiab corrosion tsis kam rau cov ntaub ntawv thiab cov rooj tog ua ke.

Txwv los txiav txim siab

Mig vuam stainless hlau muaj ob peb lub drawbbacks:

• Tus nqi: Stainless hlau hlau thiab ntaub thaiv npog roj (Argon {{{}} cov pa sib tov) yog cov khoom sib xyaw.
• Cua siab: Cov roj thaiv hluav taws xob yooj yim cuam tshuam los ntawm cov ntawv sau, yog li yuav tsum tau sib tw tawm sab nraud yuav tsum muaj cua daj cua dub. Txawm tias lub teeb ci tuaj yeem qhia cov oxygen, puas tsuaj rau Weld.
• Cov khoom siv nyias nyias: Rau cov hlau stainless hauv qab 20 gauge (cov ntaub pua nyias nyias), Tig vuam yog qhov zoo dua {- los ntawm.

Hauv cov ntsiab lus, MIG vUAM yog ib txoj kev siv hluav taws xob, ua kom muaj weld weld weld welder, 308l / 316l filler xaim, thiab argon- pa oxygen gas. Los ntawm kev tswj cov cua sov, tswj cov arc ruaj khov, thiab ntxuav cov hlau ua ntej, koj tuaj yeem ua tiav cov zog, kev tiv thaiv welds haum rau txhua yam ntawm DIY cov phiaj xwm rau kev lag luam Machinery. Thaum nws xav tau kev saib xyuas ntau dua li cov vuam me me, MIG txoj kev nrawm thiab versatility ua nws xaiv qhov kev xaiv zoo rau kev ua haujlwm ntawm cov hlau stainless.
