MIG welding plus gas li nruab nrab los tiv thaiv cov hlau tee, vuam molten pas dej kub kub hlau arc vuam txoj kev thiab vuam cheeb tsam, hu ua MIG arc vuam.Nrog rau cov khoom tseem ceeb ntawm cov roj inert (Ar lossis Nws) shielded arc vuam txoj kev hu ua melting inert gas tiv thaiv vuam.MIG vuam nyob rau hauv tas li ntawd mus siv hlau hlau es tsis txhob vuam torch tungsten electrode sab nraum.Lwm yam thiab TIG vuam.Yog li ntawd, vuam hlau yog los ntawm arc melting rau hauv weld cheeb tsam.Hluav taws xob tsav cov menyuam raws li cov vuam hlau los ntawm cov spool xav tau rau hauv vuam teeb.Dc hluav taws xob arc cua sov qhov chaw yog, tab sis lub polarity thiab TIG vuam yog siv rau qhov opposite.Cov roj tiv thaiv sib txawv thiab xav koom nrog cov roj argon ua 1% oxygen los txhim kho kev ruaj ntseg ntawm arc.

MIG vuam tuaj yeem siv semi-automatic lossis tsis siv neeg vuam, ntau yam kev siv.MIG vuam tuaj yeem welding ntau yam ntaub ntawv, tab sis nyob rau hauv xyoo tas los no vim yog cov pa roj carbon thiab cov hlau tsis tshua muaj hlau, thiab ntau dua siv argon-nplua nuj hybrid GMAW vuam, thiab tsis tshua muaj cov roj inert welding, hlau inert gas, yog li ntawd, welding feem ntau siv. rau vuam aluminium, magnesium, tooj liab, titanium thiab nws cov alloys thiab stainless hlau.MIG welding tuaj yeem welding ntau thickness ntawm lub workpiece, tab sis qhov tseeb ntau lawm yog feem ntau nyias phaj vuam, xws li daim ntawv thickness 2 hli hauv qab no siv hlau inert gas vuam vuam zoo dua.MIG vuam tuaj yeem ua tiav kev tswj hwm ntawm txhua txoj haujlwm vuam.

MIG vuam muaj semi-automatic thiab tsis siv neeg hom.Tsis siv neeg MIG vuam siv tau rau cov kev cai ntawm longitudinal seam, girth thiab kab rov tav txoj hauj lwm ntawm vuam;Luv semiautomatic MIG vuam feem ntau yog siv rau tack welding, vuam tsis tu ncua vuam thiab txhuas lub taub hau, cov yeeb nkab sib txuas thiab cov nplhaib txuas ntxiv ntawm vuam.Nrog rau kev nthuav dav ntawm MIG vuam daim ntawv thov, tsuas yog los ntawm Ar lossis Nws yog qhov nyuaj los ua kom tau raws li qhov xav tau ntawm cov roj thaiv kev tiv thaiv, yog li tsim cov roj inert los koom nrog me me ntawm cov roj reactive xws li oxygen, carbon dioxide gas sib tov ua shielding gas.Feem ntau hu ua yaj reactive gas, vuam lossis MAG.Nyob rau hauv lub vuam qauv ntawm ntau lawm, tshwj xeeb tshaj yog nyob rau hauv high alloy thiab nonferrous hlau thiab lawv alloys nyob rau hauv zus tau tej cov vuam, MIG vuam occupies tseem ceeb heev txoj hauj lwm.
