MIG welding e ka sebelisoa semi-automatic kapa automatic welding, mefuta e mengata ea lits'ebetso.MIG tjheseletsa ka tjheseletsa mefuta e fapaneng ya thepa, empa lilemong tsa morao tjena ka lebaka la k'habone le low- alloy steels, 'me ho feta ho sebelisa argon-rich hybrid GMAW tjheseletsa, le ka seoelo hloekileng inert khase tjheseletsa, tšepe inert khase, ka hona, tjheseletsa e sebediswa hangata. bakeng sa ho tjheseletsa aluminium, magnesium, koporo, titanium le alloys ea eona le tšepe e sa hloekang.MIG tjheseletsa ka tjheseletsa botenya tse fapa-fapaneng tsa workpiece, empa tlhahiso ea sebele ka kakaretso e tšesaane poleiti tjheseletsa, tse kang lakane botenya 2mm ka tlaase ho sebelisa tšepe inert khase tjheseletsa tjheseletsa molemo.MIG welding e ka fihlella taolo e bohlale ea li-welding tsohle tsa maemo.

MIG welding e na le mekhoa ea semi-automatic le ea othomathike.Automatic MIG welding e sebetsa ho melao ea longitudinal seam, girth le rapameng boemo ba tjheseletsa;Short semiautomatic MIG welding e sebelisoa haholo bakeng sa welding ea tack, weld discontinuous welding le hlooho ea setshelo sa aluminium, motsoako oa liphaephe le ho matlafatsa lesale la weld.Hammoho le ho atolosoa ha MIG dikopo tjheseletsa, feela ka Ar kapa O thata ho kopana le tlhokahalo ea ho sireletsa khase, kahoo ntshetswa pele ka khase inert ho ikopanya le palo e nyenyane ea likhase reactive tse kang oksijene, carbon dioxide khase motsoako e le ho sireletsa khase.Hangata e bitsoa melt reactive gas, welding kapa MAG.Ka sebopeho sa tjheseletsa sa tlhahiso, haholo-holo ka alloy e phahameng le litšepe tse nonferrous le lialloys tsa tsona ha ho etsoa welding, MIG welding e nka boemo ba bohlokoa haholo.
