Cov xov hlau MIG ua lub luag haujlwm tseem ceeb hauv kev vuam niaj hnub. Yuav kom ua tiav cov txiaj ntsig vuam zoo, peb yuav tsum paub yuav ua li cas xaiv thiab siv cov xov hlau MIG kom raug.
Yuav ua li cas xaiv MIG hlau?
Ua ntej tshaj plaws, peb yuav tsum ua raws li cov khoom siv hauv paus, ntau hom khoom siv hauv paus txiav txim siab qhov kev xaiv ntawm cov hlau. Cov ntaub ntawv hauv paus feem ntau yog carbon hlau, stainless hlau, txhuas alloy thiab lwm yam. Rau cov hlau carbon, kev xaiv ntawmhlau vuamYuav tsum raws li nws qib zog. Cov hlau carbon uas tsis muaj zog tuaj yeem xaiv cov hlau vuam carbon steel ib txwm, thaum cov hlau carbon uas muaj zog siab xav tau cov hlau muaj zog siab dua kom ntseeg tau tias kev ua haujlwm tom qab vuam. Muaj ntau hom hlau stainless, suav nrog austenitic stainless hlau, ferritic stainless hlau, martensitic stainless hlau thiab lwm yam. Txhua qib hlau stainless muaj nws cov tshuaj lom neeg tshwj xeeb thiab cov yam ntxwv ua tau zoo, yog li koj yuav tsum xaiv cov hlau stainless kom phim, txhawm rau kom ntseeg tau tias qhov kev tiv thaiv corrosion thiab cov khoom siv kho tshuab ntawm qhov vuam yog sib xws nrog cov khoom siv niam txiv.
Tau kawg, qhov yuav tsum tau ua haujlwm vuam nrog peb nyob rau hauv qhov kev txiav txim siab, qhov yuav tsum tau ua kom muaj zog ntawm qhov vuam yog ib qho tseem ceeb rau kev xaiv cov hlau. Yog tias qhov vuam xav tau tiv taus cov khoom hnyav, ces yuav tsum xaiv cov hlau muaj zog dua. Qhov no ua kom ntseeg tau tias qhov sib koom ua ke vuam yuav tsis tawg thaum siv. Rau kev vuam nrog cov kev xav tau tiv thaiv corrosion, xws li cov khoom siv siv hauv qhov chaw ib puag ncig hnyav xws li kev lag luam tshuaj lom neeg thiab hiav txwv, nws yog qhov tsim nyog los xaiv cov hlau vuam nrog kev tiv thaiv corrosion sib xws. Yog tias cov khoom siv vuam xav tau muaj kev tawv zoo lossis kev ua haujlwm kub qis, koj kuj yuav tsum ua tib zoo xaiv cov hlau kom haum rau cov kev xav tau tshwj xeeb no.
Qhov thib ob, peb yuav tsum txiav txim siab seb lub hlau txoj kab uas hla yog dab tsi. Kev xaiv lub hlau txoj kab uas hla thiab qhov tam sim no ntawm vuam, qhov chaw vuam thiab qhov tuab ntawm cov khoom siv hauv paus yog qhov sib txuas ze heev. Feem ntau, qhov tam sim no vuam loj dua thiab cov khoom siv hauv paus tuab dua yuav tsum tau siv cov hlau tuab dua. Qhov no yog vim tias cov hlau tuab dua tuaj yeem tiv taus cov tam sim no siab dua thiab tseem muab cov hlau ntxiv ntau dua kom ntseeg tau tias lub zog ntawm qhov vuam. Piv rau qhov vuam phaj nyias, cov hlau txoj kab uas hla me dua feem ntau raug xaiv kom txo qhov kub ntawm vuam thiab tiv thaiv kev kub hnyiab thiab kev cuam tshuam. Hauv cov chaw vuam sib txawv, nws tseem tsim nyog los xaiv qhov txoj kab uas hla ntawm cov hlau vuam. Piv txwv li, hauv qhov chaw vuam sab saud, vim qhov nyuaj ntawm kev ua haujlwm, txhawm rau kom yooj yim rau kev ua haujlwm thiab xyuas kom meej qhov zoo ntawm kev vuam, yuav tsum xaiv cov hlau nyias dua.
Ntxiv rau qhov no, peb yuav tsum muab cov txheej txheem vuam sib xyaw ua ke hauv kev xaiv cov hlau, cov txheej txheem vuam MIG sib txawv, xws li vuam tam sim no, voltage, vuam ceev, thiab lwm yam, kuj muaj qhov cuam tshuam tseem ceeb rau kev xaiv cov hlau. Yuav tsum ua raws li cov txheej txheem vuam tiag tiag los xaiv cov hlau tuaj yeem hloov kho rau cov kev ntsuas no. Hauv qhov xwm txheej ntawm kev vuam tam sim no siab thiab kev vuam ceev ceev, nws yog ib qho tseem ceeb kom ntseeg tau tias cov hlau tuaj yeem yaj sib npaug thiab tsim cov vuam zoo hauv cov txheej txheem vuam ceev ceev. Nws yog qhov tsim nyog los xaiv cov hlau vuam nrog cov khoom zoo thiab ruaj khov.
Tib lub sijhawm, peb kuj yuav tsum xav txog qhov ruaj khov ntawm cov hlau thiab kev pabcuam tom qab muag. Xaiv lub npe hlau uas muaj lub koob npe zoo thiab cov channel xa khoom txhim khu kev qha kom ntseeg tau tias yuav tsis muaj qhov tsis txaus ntawm cov hlau hauv cov txheej txheem vuam. TANKII Alloy muaj ntau yam hlau vuam nrog qhov ruaj khov zoo, yog tias koj xav tau lawv, thov hu rau peb.
Tom qab ntawd yog dab tsi yog cov kev ceev faj rau kev sivMIG vuam hlau?
Thawj qhov uas yuav tsum hais yog tias hais txog cov khoom siv, nws yog ib qho tseem ceeb heev uas yuav tsum xaiv lub tshuab vuam uas haum rau MIG vuam. Kev ua haujlwm ntawm lub tshuab vuam yuav tsum ruaj khov, thiab qhov tso zis tam sim no thiab voltage yuav tsum raug. Tib lub sijhawm, xyuas kom tseeb tias lub tshuab vuam tau av zoo kom tiv thaiv kev raug hluav taws xob. Kev ua haujlwm ib txwm ntawm lub kaw lus pub hlau yog qhov tseem ceeb rau kev ua kom zoo ntawm kev vuam. Lub tshuab pub hlau yuav tsum khiav zoo thiab lub siab ntawm lub log pub hlau yuav tsum nruab nrab kom tsis txhob pub hlau tsis ruaj khov lossis hlau plam. Tsis tas li ntawd, lub raj pub hlau yuav tsum tau ntxuav tas li kom tiv thaiv kev txhaws.
Qhov kev xaiv cov roj tiv thaiv kuj tseem ceeb heev. Cov roj tiv thaiv feem ntau yog argon, helium lossis sib xyaw ua ke. Xyuas kom tseeb tias qhov huv ntawm cov roj tiv thaiv ua tau raws li qhov yuav tsum tau ua kom ntseeg tau tias qhov vuam zoo. Kev hloov kho qhov ntws ntawm cov roj tiv thaiv yog qhov tseem ceeb heev. Feem ntau, cov roj ntws yuav tsum tau hloov kho raws li qhov tam sim no vuam, txoj kab uas hla ntawm cov hlau thiab qhov chaw vuam thiab lwm yam. Ntxiv rau cov txheej txheem vuam, kom ntseeg tau tias muaj kev tiv thaiv cov roj zoo nyob ib puag ncig thaj chaw vuam, kom tsis txhob muaj huab cua nkag mus rau hauv lub pas dej yaj.
Yuav tsum nco ntsoov tias feem ntau peb xaiv cov hlau MIG raws li cov khoom siv, tuab thiab qhov yuav tsum tau vuam ntawm cov khoom siv hauv paus. Lub cheeb tsam, cov tshuaj lom neeg sib xyaw thiab cov khoom siv kho tshuab ntawm cov hlau vuam yuav tsum phim cov khoom siv hauv paus. Peb yuav tsum xyuas qhov zoo ntawm cov hlau vuam ua ntej siv, thiab ntxuav nws yog tias muaj xeb thiab roj. Tswj qhov ntev ntawm cov hlau vuam. Feem ntau hais lus, qhov ntev ntawm cov hlau yog li 10 npaug ntawm txoj kab uas hla ntawm cov hlau yog qhov tsim nyog. Kev ncab tawm qhov ntev ntev dhau yuav ua rau muaj kev tiv thaiv ntau ntxiv, yog li cov hlau overheating, cuam tshuam rau qhov zoo ntawm kev vuam.
Tsis tas li ntawd xwb, qhov chaw vuam sib txawv muaj cov kev cai sib txawv rau cov txheej txheem vuam. Hauv kev vuam tiaj tiaj, vuam ntsug, vuam kab rov tav thiab vuam rov qab, yuav tsum kho cov kev teeb tsa vuam thiab cov txheej txheem ua haujlwm kom ntseeg tau tias qhov zoo ntawm kev vuam. Rau kev vuam qee cov ntaub ntawv xws li cov phaj tuab lossis cov hlau carbon siab, yuav tsum tau ua ntej kom tsis txhob tawg. Tib lub sijhawm, qhov kub ntawm cov txheej txheem yuav tsum tau tswj kom tsis txhob siab dhau lossis qis dhau. Thaum lub sijhawm vuam, slag thiab spatter ntawm qhov chaw ntawm qhov vuam yuav tsum tau ntxuav kom raws sijhawm kom ntseeg tau tias qhov zoo li ntawm qhov vuam thiab kev vam meej ntawm kev vuam tom ntej.
