Kuwotcherera kwa MIG kuphatikiza gasi ngati sing'anga kuteteza dontho lachitsulo, kuwotcherera dziwe losungunuka kutentha kwazitsulo zowotcherera arc ndi malo owotcherera, otchedwa MIG arc kuwotcherera.Ndi chingwe cholimba chapakati cha gasi wa inert (Ar kapena He) wotetezedwa ndi njira yowotcherera ya arc yotchedwa kusungunula gasi woteteza chitetezo.Kuwotcherera kwa MIG kuphatikiza kugwiritsa ntchito waya wachitsulo m'malo mowotcherera tochi ya tungsten electrode kunja.Zina ndi kuwotcherera kwa TIG.Chifukwa chake, waya wowotcherera ndi arc kusungunuka mu weld zone.Magetsi oyendetsa galimoto molingana ndi waya wowotcherera kuchokera ku spool wofunikira mu tochi yowotcherera.Dc electric arc heat source ndi, koma polarity ndi TIG kuwotcherera amagwiritsidwa ntchito mosiyana.Mpweya woteteza ndi wosiyana ndipo ndikufuna kulowa nawo mu mpweya wa argon kukhala 1% mpweya kuti ukhale wokhazikika wa arc.

Kuwotcherera kwa MIG kumatha kugwiritsidwa ntchito kuwotcherera theka-odziwikiratu kapena kungowotcherera, mapulogalamu osiyanasiyana.MIG kuwotcherera akhoza kuwotcherera zosiyanasiyana zipangizo, koma m'zaka zaposachedwapa chifukwa cha carbon ndi otsika- aloyi zitsulo, ndi zambiri ntchito Argon-olemera wosakanizidwa kuwotcherera GMAW, ndi kawirikawiri koyera inert mpweya kuwotcherera, zitsulo inert mpweya, Choncho, kuwotcherera ambiri ntchito. kwa kuwotcherera aluminium, magnesium, mkuwa, titaniyamu ndi ma aloyi ake ndi chitsulo chosapanga dzimbiri.kuwotcherera MIG akhoza kuwotcherera makulidwe osiyanasiyana a workpiece, koma kupanga kwenikweni zambiri woonda mbale kuwotcherera, monga pepala makulidwe 2mm pansipa ntchito zitsulo inert kuwotcherera mpweya bwino.kuwotcherera kwa MIG kumatha kukwaniritsa kuwongolera mwanzeru pazowotcherera malo onse.

Kuwotcherera kwa MIG kuli ndi mitundu yodziyimira yokha komanso yodziwikiratu.Makinawa kuwotcherera MIG ndi ntchito malamulo a utali msoko, girth ndi yopingasa udindo wa kuwotcherera;Short semiautomatic MIG kuwotcherera makamaka ntchito kuwotcherera tack, kuwotcherera discontinuous ndi aluminiyamu chidebe mutu, chitoliro olowa ndi kulimbikitsa mphete kuwotcherera.Pamodzi ndi kukula kwa MIG ntchito kuwotcherera, kokha ndi Ar kapena Iye n'kovuta kukumana ndi kufunika kutchinga mpweya, motero anayamba mu mpweya inert kuti agwirizane pang'ono zotakasika mpweya monga mpweya, mpweya woipa osakaniza mpweya woipa ngati kutchinga mpweya.Nthawi zambiri amatchedwa melt reactive gasi, kuwotcherera kapena MAG.Mu mawonekedwe kuwotcherera kupanga, makamaka aloyi mkulu ndi zitsulo nonferrous ndi aloyi awo pakupanga kuwotcherera, MIG kuwotcherera ali otanganidwa kwambiri.
