Kodi kuwotcherera kwa MIG ndi chiyani?
Kuwotcherera kwa Mig ndi kuwotcherera kwa Metal Inert Gas komwe ndi njira yowotcherera ya arc.Kuwotcherera kwa MIG kumatanthauza kuti waya wowotcherera amalowetsedwa mu dziwe la weld ndi mfuti yowotcherera mosalekeza.Waya wowotcherera ndi zida zoyambira zimasungunuka pamodzi kupanga cholumikizira.Mfuti imadyetsa mpweya wotetezera kuti uteteze dziwe la weld ku zowonongeka zoyendetsedwa ndi mpweya.Kodi mphamvu ya gasi iyenera kukhala yotani pa kuwotcherera kwa MIG.Choncho kuperekera kwa gasi ndikofunika kwambiri ku Mig kuwotcherera.Nthawi zambiri, anthu amasankha argon , CO2 kapena Gasi Wosakanikirana kukhala chishango cha gasi.
Kodi MiG welding gas flow rate CFH iti?
Onani tchati pansipa.
Tchati cha MIG Shielding Gas Flow Rate
(Kwa Argon Mixtures ndi CO2)
http://www.netwelding.com/MIG_Flow%20Rate-Chart.htm
1MPa=1000KPa=10.197kgf/cm2=145.04PSI 1M3/h=16.67LPM=35.32SCFH
Kuwotcherera kwa Argon ndi kuwotcherera MIG kuli ndi mitundu iwiri, yowongolera ma flow gauge ndi owongolera mita.
Mutha kusankha mtundu womwe mumakonda.Kusiyana pakati pawo kuli mu njira yowerengera mpweya wa gasi.Imodzi imadutsa pa flow gauge ndipo ina imadutsa pa flow meter.
Momwe mungakhazikitsire chowongolera gasi pa chowotcherera cha MIG?
Gawo 1
Khazikitsani silinda yamafuta ya chowotcherera cha MIG mu chotengera, ndikumangirira tcheni mozungulira botololo.
Gawo 2
Yang'anani ma hoses omwe ali ndi chowongolera mpweya.Ngati mutapeza zowonongeka, sinthanani.
Gawo 3
Yang'anani ndikutsimikizira kuti valavu ya silinda yamagetsi yatsekedwa bwino.
Khwerero 4
Tembenuzani chowongolera chowongolera gasi, kuti mutsimikizire kuti chatsekedwa.Lumikizani zomangira za chowongolera mpweya ku valavu ya botolo la gasi.Tembenuzani mtedza wokhoma mozungulira mpaka dzanja litalimba.Ndiye zokhoma nati ndi wrench.
Gawo 5
Yatsani valavu ya gasi ndi chowongolera chowongolera.
Gawo 6
Yang'anani kutuluka kwa gasi mozungulira chowongolera gasi, mapaipi, ndi zolumikizira.Ngakhale kuti mpweya wotchinga umakhala wopanda mphamvu, koma kutayikirako kumabweretsa kutayika kwa gasi ndipo m'dera lotsekeka kungayambitse kupuma.
Gawo 7
Sinthani kuchuluka kwa gasi kukhala CFH yoyenera yomwe mukufuna .iyenera kukhala pakati pa 25 ndi 30 CFH nthawi zambiri.
Gawo 8
Yatsani chowotcherera cha MIG.Dinani choyambitsa cha MIG mfuti kuti mutsegule valavu ya gasi.
