Lo lus teb yog lub resounding yog - mig (hlau inert roj) vuam tsis tsuas yog muaj ib txoj hauv kev nrov tshaj plaws thiab muaj txiaj ntsig zoo rau kev ua li ntawd. Cov hlau me me, paub txog nws cov ntsiab lus carbon qis (feem ntau 0.25% rau 0.30%) thiab kho kom zoo dua qub, kho tsheb, thiab txawm tias DIY cov phiaj xwm. Peb tshawb nrhiav vim li cas thiaj vuam yog qhov zoo tagnrho rau cov me me, cov kev txiav txim siab tseem ceeb, thiab yuav ua li cas kom ua tiav cov txiaj ntsig tau zoo.
Vim li cas Mig vuam ua haujlwm zoo heev rau cov me
Mild Steel lub tshuaj lom neeg muaj pes tsawg leeg yog qhov laj thawj tseem ceeb rau nws qhov sib raug zoo nrog MIG VUAM. Nws cov ntsiab lus muaj roj carbon qis me me tsis muaj kev pheej hmoo ntawm kev ua kom tawv nqaij tawv lossis ua kom muaj kev phom sij hauv weld uas ib puag ncig tab sis tsis yog melted. Qhov no txhais tau tias cov weld thiab ib puag ncig hlau khaws cov qauv ua kom zoo thiab lub zog, txo lub caij nyoog ntawm kev tawg. Tsis tas li ntawd, cov hlau me muaj qhov tsis tshua muaj tseeb piv rau cov khoom siv cua sov, uas pub rau kev ua kom zoo ntawm cov hlau hauv paus thiab cov xaim xaim.
Mig vuam nws tus kheej txhim kho qhov kev sib raug zoo ntawm nws cov qauv tseem ceeb. Cov txheej txheem siv cov hlau txuas ntxiv hlau electrode uas ua raws li cov tub lim hlau weld thiab cov kev sib xyaw rau lub arc, feem ntau yog cov kev sib xyaw ntawm cov tub rog weld (hydrogen, thiab hydrogen). Rau cov hlau me me, cov roj tiv thaiv cov ntaub thaiv cov pa tawm hws, oxidation, thiab lwm yam tsis zoo, ua kom huv si Welds. Cov kab hlau pub txuas ntxiv kuj tso cai rau cov nqi thauj khoom siab, ua kom Mig vuam nrawm dua li cov haujlwm sib tw me me rau cov haujlwm loj lossis rov ua haujlwm.
Cov khoom siv thiab cov khoom siv xav tau
Txhawm rau mig weld me me hlau me, koj yuav xav tau ob peb tus tseem ceeb, tag nrho cov uas tau yooj yim muaj thiab zoo - haum rau cov khoom siv:
Mig Welder: 11020V lossis 220V Mig Welder ua haujlwm rau cov hlau me me, nrog 220V qauv muab ntau cov hluav taws xob ntau dua rau cov ntawv tuab (ntau dua 1/4 nti). Feem ntau Mig Welders muaj nqis qhia tshwj xeeb rau cov hlau me me, qhov yooj yim teeb tsa.
Cov xaim xaim: Qhov kev xaiv txheem yog ER70S-6, ib qho xaim hlau tsim rau cov hlau me me. Nws muaj cov deaxidizing (zoo li silicon thiab manganese) uas tawm tsam impurities nyob rau hauv lub hauv paus hlau, kom muaj zog, ductile veel. Hlau hlau diam ntawm ntau ntawm 0.023 nti (rau nyias daim ntawv hlau) rau cov ntawv me me), rau 0.030 ntiv hauv nruab nrab.
Kev thaiv cov roj: kev sib xyaw ntawm 75% Argon thiab 25% carbon dioxide (75/25 AR / CO₂) yog cov qauv kev lag luam rau cov hlau mig vuam. Lub argon ruaj khov lub arc, thaum lub koom haum ntxiv rau kev nkag mus thiab pab tswj lub ntsej muag. Rau cov hobbyists lossis cov phiaj xwm me me, pre {-}} sib xyaw thooj voos kheej yog yooj yim rau cov khoom. Muaj qee kis, 100% CO₂ tuaj yeem siv tau, txawm hais tias nws yuav tsim ntau lub ntsej muag thiab lub arc tsawg dua.
Npaj cov cuab yeej: Cov hlau me me yuav tsum tau npaj tsawg dua piv rau lwm cov hlau lossis sib tsoo kom tshem tawm cov xeb, roj, pleev xim, lossis zeb nplai yog qhov tseem ceeb. Txawm tias cov me me ntawm cov kev paug me me tuaj yeem ua rau porosity lossis qaug zog fusion.
Cov Ntsiab Zoo ntawm MIG VUAM MOJ TEJ YEEB
Yooj yim ntawm kev siv: mig vuam yog tus pib - Tus phooj ywg, tshwj xeeb tshaj yog rau cov hlau me me. Cov hlau txuas txuas ntxiv thiab ua tau ruaj khov txo qhov kev kawm nkhaus sib xyaw kom lo vuam, ua rau muaj kev nkag mus rau cov diyers lossis cov welders tshiab.
Kev nrawm thiab ua tau zoo: tus nqi tshaj tawm ntawm Mig Vuam tso cai rau cov haujlwm nrawm dua, txawm tias vuam ib lub vaj huam sib luag lossis cov qauv nkhaus. Qhov kev ua tau zoo no yog qhov tseem ceeb ntxiv rau cov chaw ua haujlwm ntau lawm.
Cov ntaub ntawv huv si (nrog cov tshuaj tiv thaiv kom zoo, mig welds ntawm cov hlau me me yog feem ntau du, nrog minimal spatter lossis slag. Qhov no txo qhov kev xav tau rau cov lus tshaj tawm - Weld tu, txuag sijhawm thiab kev rau siab.
Versatility hauv cov thickness: mig vuam tuaj yeem ua rau cov hlau thickness me me, ntawm cov paib nyias nyias, li ntawm 24 nti lossis ntau dua nrog ntau cov kev hla). Kho cov hlau pub nrawm nrawm, voltage, thiab amperage tso cai rau kev tswj cua sov, tiv thaiv boil- los ntawm ntawm cov ntaub ntawv nyias nyias lossis cov tsis tiav ntawm cov tuab.
Tag nrho - Txoj Haujlwm muaj peev xwm: Thaum lub chaw tiaj thiab cov chaw sib txuas ua ke tau yooj yim rau cov haujlwm stiffer molten molten molten molten molten molten molten
Cov lus qhia rau kev vam meej mig vuam ntawm cov hlau me
Teem cov kev ntsuas yog: phim cov kab uas hla, voltage, thiab hlau pub ceev rau cov tuab ntawm cov me me. Yuav luag txhua tus neeg muag khoom muaj cov kab kos uas pom zoo cov chaw (piv txwv li, 0.030-nti hlau nrog 18-22 volts rau 16-lub ntsuas cua dub).
Saib xyuas kev mus ncig ua si kom tsim nyog: txav lub teeb ruaj khov kom ntseeg tau tias tsis zoo. Qeeb, thiab koj yuav pheej hmoo hlawv -} los ntawm lossis ntau dua kev kub taub hau; Kev nrawm heev, thiab cov weld kuj tsis muaj qhov nkag mus.
Tswj cov thaiv npog roj: tus nqi txaus ntawm 20-30 cubic feet ib teev (CFH) yog qhov raug. Cov roj me me pub rau kev paug; Ntau dhau lawm siv tau roj ntau dua thiab tuaj yeem ua rau muaj kev kub ntxhov.
Khaws lub teeb ua hluav taws xob: A 10-15-degree-deg kaum sab xis (Teeb tsa lub taub hau me ntsis ntawm Weld kev taw qhia) pab ncaj rau cov pa tiv thaiv roj av thiab txhim kho pom kev.
Tiv thaiv kev overheating: cov hlau me me yog nquag mus ua rog yog tias rhuab tsis sib xws. Siv cov hlua khi rau cov khoom siv nyob rau hauv qhov chaw ua ntej yuav tsum zaum kawg, thiab weld hauv ntu luv, hloov ntu mus faib cua sov.
Txwv los txiav txim siab
Thaum mig vuam yog qhov zoo heev rau cov hlau me me, nws muaj ob peb yam kev txwv. Kev siv sab nraum zoov yog qhov nyuaj vim tias muaj hluav taws xob roj, ua rau muaj roj ntsha (uas tsis xav tau kev tiv thaiv roj) Ib qho ntxiv, Mig vuam yuav tsum muaj lub zog hluav taws xob thiab cov roj kheej lub tog raj kheej, uas tuaj yeem ua tau cov khoom siv vuam txuas ntxiv rau cov chaw tej thaj chaw deb. Txawm li cas los xij, cov teeb meem no feem ntau yog tus txheej txheem cov txiaj ntsig rau cov hlau me me.
