Thaum nws los txog rau MIG vuam, nws yog ib qho tseem ceeb rau cov welding tshiab pib nrog lub hauv paus los tsim lub hauv paus ruaj khov rau kev vam meej.Cov txheej txheem feem ntau zam txim rau, ua rau nws yooj yim kawm dua TIG vuam, piv txwv li.Nws tuaj yeem welding feem ntau cov hlau thiab, raws li cov txheej txheem noj tsis tu ncua, muaj kev nrawm dua thiab ua haujlwm tau zoo dua li cov hlua vuam.
Nrog rau kev xyaum, kev paub txog qee cov ntaub ntawv tseem ceeb tuaj yeem pab cov welding tshiab kom nkag siab txog MIG vuam txheej txheem
Vuam kev nyab xeeb
Thawj qhov kev txiav txim siab rau cov welding tshiab yog vuam kev nyab xeeb.Nws yog ib qho tseem ceeb uas yuav tsum tau nyeem thiab ua raws li tag nrho cov ntawv sau npe thiab cov cuab yeej siv Tus Tswv Cuab Cov Lus Qhia ua tib zoo ua ntej kev teeb tsa, kev khiav hauj lwm, lossis kev pabcuam vuam khoom.Welders yuav tsum hnav qhov muag tiv thaiv kom tsis txhob muaj qhov kub hnyiab thiab ci ntsa iab.Ib txwm hnav tsom iav kev nyab xeeb thiab lub kaus mom hlau vuam teeb rau qhov tsim nyog ntxoov ntxoo.Cov khoom siv tiv thaiv tus kheej kom zoo yog qhov tseem ceeb los tiv thaiv daim tawv nqaij los ntawm hluav taws xob poob siab thiab kub hnyiab.Qhov no suav nrog:
· Tawv khau lossis khau boots.
· Cov hnab looj tes tawv tawv lossis nplaim taws-resistant vuam
· Nplaim-resistant vuam tsho los yog lub tes tsho vuam
Kev ua pa txaus kuj yog qhov tseem ceeb ntawm kev nyab xeeb.Welders yuav tsum nco ntsoov khaws lawv lub taub hau tawm ntawm lub weld plume thiab nco ntsoov tias thaj chaw uas lawv vuam muaj qhov cua txaus.Qee hom fume extraction tej zaum yuav xav tau.fume extraction phom uas tshem tawm cov pa tawm ntawm lub arc kuj tseem pab tau, thiab muaj txiaj ntsig zoo piv rau hauv pem teb lossis qab nthab.
Vuam hloov hom
Nyob ntawm cov khoom siv hauv paus thiab tiv thaiv cov roj, cov welders tuaj yeem welding hauv ntau hom kev hloov vuam.
luv luv Circuit Court yog feem ntau rau cov ntaub ntawv thinner thiab ua hauj lwm nyob rau hauv qis welding voltage thiab hlau pub ceev, yog li nws yog qeeb dua lwm yam txheej txheem.Nws kuj tseem yuav tsim cov spatter uas yuav tsum tau ntxuav tom qab vuam, tab sis tag nrho, nws yog cov txheej txheem yooj yim siv.
Kev hloov pauv thoob ntiaj teb ua haujlwm ntawm cov xaim pub nrawm dua thiab cov vuam hluav taws xob ntau dua li luv luv thiab ua haujlwm rau vuam nrog flux-cored xaim nrog 100% carbon dioxide (CO2) (saib cov ntsiab lus ntawm CO2 hauv ntu txuas ntxiv).Nws tuaj yeem siv rau ntawm 1/8-nti thiab cov ntaub ntawv tuab dua.Zoo li luv luv-circuit MIG welding, hom no tsim spatter, tab sis nws yog cov txheej txheem ceev ceev.
Txau hloov pauv muaj qhov du, ruaj khov arc, ua rau nws txaus siab rau ntau tus neeg siv khoom tshiab.Nws ua haujlwm ntawm cov vuam amperages siab thiab voltage, yog li nws yog ceev thiab tsim tau.Nws ua haujlwm zoo ntawm cov ntaub ntawv hauv paus uas yog 1/8 nti lossis ntau dua.
Vuam shielding gas
Ntxiv nrog rau kev tiv thaiv lub pas dej ua ke los ntawm huab cua, hom shielding gas siv rau MIG vuam cuam tshuam kev ua haujlwm.Weld nkag mus, arc stability thiab mechanical zog nyob ntawm shielding gas.
Ncaj nraim cov pa roj carbon dioxide (CO2) muaj qhov sib sib zog nqus vuam tab sis muaj qhov tsis tshua ruaj khov arc thiab ntau spatter.Nws yog siv rau luv luv Circuit Court MIG vuam.Ntxiv argon rau CO2 sib tov tso cai rau kev siv tshuaj tsuag hloov mus rau kev tsim khoom ntau dua.Qhov sib npaug ntawm 75% argon thiab 25% yog qhov ntau.
Tshaj qhov hauv paus
Nrog rau kev xyaum, kev paub txog qee cov ntaub ntawv tseem ceeb tuaj yeem pab cov welding tshiab kom nkag siab txog MIG vuam txheej txheem.Nws tseem yog ib qho tseem ceeb kom paub txog cov khoom siv, suav nrog MIG vuam phom thiab cov hlua vuam.Kev nkag siab txog kev xaiv thiab tswj cov cuab yeej no tuaj yeem mus deb mus rau kev tsim cov vuam zoo, zoo thiab tsim tau zoo.
