MIG xov hlau ua lub luag haujlwm tseem ceeb hauv kev siv vuam niaj hnub. Txhawm rau kom ua tiav cov txiaj ntsig vuam zoo, peb yuav tsum paub xaiv thiab siv Mig cov xov hlau kom raug.
Yuav xaiv Mig Hlau?
Ua ntej tshaj plaws, peb yuav tsum tau raws li cov khoom siv hauv paus, ntau hom ntawm cov khoom siv txiav txim siab cov kev coj ntawm xaim xaiv. Cov ntaub ntawv hauv paus yog cov roj carbon hlau, hlau hlau, txhuas alloy thiab lwm yam. Rau cov hlau hlau, kev xaiv ntawmVuam hlauyuav tsum ua raws li nws lub zog. Low-muaj zog carbon steel tuaj yeem xaiv cov hlau steel hlau vuam hlau yuav tsum muaj dua lub zog hlau kom ntseeg tau tias kev ua tau zoo tom qab vuam. Muaj ntau ntau hom hlau stainless, suav nrog Austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau thiab lwm yam. Txhua qib stainless hlau muaj nws tus kheej cim tshuaj lom neeg thiab kev ua tau zoo, txhawm rau kom ntseeg tau tias cov khoom siv corrosion, txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob tsis sib haum nrog cov khoom siv ntawm niam txiv.
Ntawm chav kawm, kev siv vuam kev ua tau zoo nrog peb hauv kev piav qhia txog kev txiav txim siab, cov muaj zog uas yuav tsum muaj ib qho tseem ceeb rau kev xaiv ntawm xaim. Yog tias tus weld xav tau withstand siab loads, ces cov hlau siab dua hlau yuav tsum tau xaiv. Qhov no kom ntseeg tau tias kev sib koom ua ke welded yuav tsis txhob ua kom dhau thaum siv. Rau vuam nrog corrosion tsis kam, xws li workpieces siv nyob rau hauv kev lag luam hnyav xws li lub hiav txwv, nws yog ib qho tsim nyog los xaiv corrosion tsis kam. Yog tias welded workpiece xav tau kev ua tau zoo lossis tsawg-kub ua tau zoo, koj kuj yuav tsum tau ua tib zoo xaiv cov hlau tsim nyog kom ua tau raws li cov cai tshwj xeeb no.
Thib ob, peb yuav tsum txiav txim siab cov kab hlau. Qhov kev xaiv ntawm xaim cov taub thiab vuam tam sim no, txoj haujlwm vuam thiab cov pob hauv paus cov ntaub tuab yog sib cuam tshuam. Feem ntau hais lus, cov vuam loj dua tshiab thiab tuab cov khoom siv yuav tsum tau siv cov hlau thicker. Qhov no yog vim tias cov xov hlau tuab tuaj yeem tiv thaiv cov dej ntws ntau dua thiab tseem muab cov tub rog ntau dua los ua kom muaj zog ntawm Weld. Hauv kev sib piv rau nyias phaj vuam, me dua txoj kab uas hla me me tau raug xaiv nyob rau hauv kev txiav txim kom tsawg vuam kub tawm tswv yim thiab tiv thaiv kev hlawv-dhau thiab distortion. Hauv cov chaw vuam sib txawv, nws tseem tsim nyog los xaiv qhov haum uas tsim nyog ntawm vuam hlau. Piv txwv li, nyob rau hauv lub upward vuam txoj hauj lwm, vim muaj kev nyuaj ntawm kev ua haujlwm thiab xyuas kom meej lub vuam zoo, yuav tsum xaiv lub xov hlau thinner.
Ntxiv rau qhov no, peb yuav tsum tau muab cov txheej txheem vuam hauv kev xaiv cov txheej txheem tam sim no, kev sib txawv ntawm vuam, thiab lwm yam. Yuav tsum tau ua raws li cov txheej txheem vuam tiag tiag los xaiv cov hlau tuaj yeem hloov kho rau cov tsis sib haum no. Nyob rau hauv cov ntaub ntawv ntawm siab tam sim no thiab kev kub ceev vuam, nws yog ib qho tseem ceeb kom paub meej tias cov hlau muaj peev xwm yaj ua ke thiab tsim cov khoom siv vuam siab hauv cov txheej txheem nrawm. Nws yog ib qho tsim nyog los xaiv lub hlau vuam nrog cov ntawv loj loj thiab ruaj khov.
Nyob rau tib lub sijhawm, peb kuj yuav tsum xav txog kev xa khoom ruaj khov ntawm cov xaim thiab tom qab muag kev pab. Xaiv hom xaim xaim nrog lub koob npe zoo thiab txhim khu kev qha ua kom ntseeg tau tias yuav tsis muaj cov xaim tsis txaus hauv cov txheej txheem vuam. Tankii Alloy muaj ntau yam vuam hlau nrog cov khoom zoo, yog tias koj xav tau, thov hu rau peb.
Ces dab tsi yog cov kev ceev faj rau kev sivMIG VUAM HLAU?
Thawj qhov uas tau hais yog tias nyob rau hauv cov ntsiab lus ntawm cov cuab yeej, nws yog qhov tseem ceeb los xaiv cov kws kho kom haum rau MIG vuam. Cov kev ua yeeb yam ntawm cov welder yuav tsum ruaj khov, thiab cov zis tam sim no thiab voltage yuav tsum yog qhov tseeb. Nyob rau tib lub sijhawm, nco ntsoov tias cov ntaub ntawv pov tseg tau zoo los tiv thaiv hluav taws xob. Kev ua haujlwm ib txwm ntawm cov hlau pub mis yog tus yuam sij los ua kom ua kom zoo. Cov hlau pub mis ua tshuab yuav tsum khiav tau yooj yim thiab lub siab ntawm cov hlau pub mis lub log yuav tsum tau ua kom tsis txhob muaj hlau pub lossis xaim hluav taws xob. Tsis tas li ntawd, cov raj pub pub pub rau cov hlau yuav tsum tau ntxuav kom tsis tu ncua los tiv thaiv txhaws.
Kev xaiv ntawm cov roj tiv thaiv yog tseem ceeb. Cov roj tiv thaiv ntau yam yog Argon, Helium lossis kev sib xyaw ntawm lawv. Nco ntsoov tias qhov kev coj dawb huv ntawm cov pa thaiv cov roj ua tau raws li qhov yuav tsum ua kom ntseeg tau tias veel muag. Qhov tsim nyog hloov cov roj teeb yog qhov tseem ceeb heev. Feem ntau hais lus, cov roj Flow yuav tsum tau hloov kho raws li lub vuam tam sim no, xaim hluav taws xob thiab txoj haujlwm sib tw thiab lwm yam. Ntxiv rau kev siv vuam, los xyuas kom meej nkev tiv thaiv nyob ib ncig ntawm thaj chaw vuam, kom tsis txhob muaj huab cua hauv lub pas dej Molten.
Nws yuav tsum raug sau tseg tias peb feem ntau xaiv cov hlau xaim uas tsim nyog raws li cov khoom siv, tuab thiab vuam cov khoom siv ntawm cov khoom siv hauv paus. Lub cheeb, tshuaj lom neeg thiab cov khoom siv tshuaj ntsuab ntawm cov hlau vuam yuav tsum phim cov khoom siv hauv paus. Peb yuav tsum tshawb xyuas qhov chaw zoo ntawm cov hlau vuam ua ntej siv, thiab ntxuav nws yog tias muaj xeb thiab roj. Tswj lub sijhawm ncua ntev ntawm cov hlau vuam. Feem ntau hais lus, qhov ntev ntawm cov hlau yog hais txog 10 zaug lub cheeb ntawm xaim yog tsim nyog. Ncab tawm qhov ntev ntawm kev ntev dhau yuav ua rau muaj kev nce ntxiv, kom cov hlau overheating, cuam tshuam rau qhov zoo ntawm vuam vuam.
Ib qho ntxiv, txoj haujlwm vuam nyias muaj nyias qhov yuav tsum muaj rau cov txheej txheem vuam. Nyob rau hauv lub tiaj vuam, ntsug vuam, kab rov tav vuam vuam, yuav tsum kho cov qauv vuam vuam, yuav tsum kho cov qauv vuam thiab cov txheej txheem kev ua haujlwm kom ntseeg tau tias lub vuam zoo. Rau vuam ntawm qee cov ntaub ntawv xws li cov hlau tuab lossis cov pa roj carbon ntau lossis cov pa roj carbon ntau, yuav tsum tsis txhob muaj kev tawg. Nyob rau tib lub sijhawm, tus interlayer kub yuav tsum tau tswj kom tsis txhob dhau los lossis qis dhau. Thaum lub sij hawm vuam, sauv thiab sab saum npoo ntawm weld yuav tsum tau ntxuav nyob rau hauv lub sij hawm los xyuas kom cov tsos zoo ntawm kev vuam vuam tom ntej.
