Metal Inert Gasi (MIG) welding is anarc weldingnzira inoshandisa inoenderera yakasimba waya electrode inopisa uye inodyiswa mukati meweld pool kubva kune welding pfuti.Izvo zvigadziko zviviri zvakanyungudutswa pamwechete kugadzira kujoinha.Pfuti inodyisa gasi rekudzivirira padivi pe electrode ichibatsira kuchengetedza dziva re weld kubva kune zvinosvibisa mhepo.
Metal Inert Gasi (MIG) welding yakatanga kupihwa patent muUSA muna 1949 yewelding aluminium.Iyo arc uye weld pool yakaumbwa uchishandisa isina bare waya electrode yakachengetedzwa nehelium gasi, yaiwanikwa nyore panguva iyoyo.Kubva munenge muna 1952, maitiro aya akave nemukurumbira muUK wekunama aluminiyamu uchishandisa argon segasi rekudzivirira, uye nekabhoni simbi uchishandisa CO2.CO2 uye argon-CO2 musanganiswa anozivikanwa sesimbi inoshanda gasi (MAG) maitiro.MIG inzira inoyevedza kune MMA, inopa yakakwira deposition mitengo uye kugadzirwa kwakanyanya.
Maitiro Emaitiro
MIG/MAG welding inzira inosiyana-siyana inokodzera zvese zviri zviviri pepa rakatetepa uye gobvu chikamu chikamu.Arc inorohwa pakati pekupedzisira kwewaya electrode uye workpiece, ichinyungudusa ese ari maviri kuita dziva re weld.Iyo waya inoshanda sese maviri sosi yekupisa (kuburikidza nearc pane waya tip) uye yekuzadza simbi yewelding joint.Waya inodyiswa kuburikidza nechubhu yemhangura (contact tip) iyo inoitisa welding ikozvino muwaya.Dziva reweld rinodzivirirwa kubva kumhepo yakatenderedza negasi rinodzivirira rinopihwa nemumuromo wakatenderedza waya.Kudzivirira gasi kusarudzwa kunoenderana nechinhu chiri kusungirirwa uye kushandiswa.Waya inodyiswa kubva pareel nemotor drive, uye welder inofambisa mwenje wewelding uchitevedza mutsara wakabatana.Waya dzingave dzakasimba (waya dzakadhonzwa dziri nyore), kana tambo (misanganiswa inoumbwa kubva musheti yesimbi ine upfu kana kuzadza simbi).Zvekushandisa zvinowanzo kukwikwidzwa mitengo zvichienzaniswa neizvo zvemamwe maitiro.Iyo nzira inopa kugadzirwa kwepamusoro, sezvo waya inoramba ichidyiswa.
Manual MIG/MAG welding inowanzonzi semi-otomatiki maitiro, sezvo waya yekudyisa chiyero uye kureba kwearc kunodzorwa nemagetsi sosi, asi kumhanya kwekufamba uye waya chinzvimbo zviri pasi pekutonga.Maitiro acho anogona zvakare kugadziridzwa kana ese maparamita emaitiro asina kudzorwa zvakananga neanowelda, asi angangoda kugadziridzwa nemaoko panguva yewelding.Kana pasina kupindira kwemaoko kunodiwa panguva yekushongedza, maitiro anogona kunzi otomatiki.
Maitiro acho anowanzo shanda newaya yakachajiwa zvakanaka uye yakabatana kune sosi yemagetsi inopa mhepo isingaperi.Sarudzo yedhayamita yewaya (kazhinji iri pakati pe0.6 ne1.6mm) uye kumhanya kwewaya feed inotaridza maveld current, sezvo chiyero chekupisa kwewaya chinoumba kuenzana nekumhanya kwekudya.
