Uyenza njani imig weldiityhubhu zentsimbi

Ukuwelda kwe-MIG kunye negesi ephakathi ukukhusela i-droplet yesinyithi, i-welding pool etyhidiweyo yobushushu obuphezulu bendlela yokuwelda i-arc kunye nendawo yokuwelda, ebizwa ngokuba yi-MIG arc welding.Ngocingo oluluqilima lwegesi engasebenziyo (Ar okanye He) indlela yokuwelda i-arc ekhuselekileyo ebizwa ngokuba yi-welding enyibilikayo yokhuseleko lwegesi.Ukuwelda kwe-MIG ukongeza ekusebenziseni ucingo lwentsimbi endaweni yetotshi yetotshi ye-tungsten electrode ngaphandle.Okunye kunye ne-TIG welding.Ke ngoko, ucingo lwe-welding lunyibilika nge-arc kwindawo ye-weld.Irola yokuqhuba umbane ngokocingo lokuwelda ukusuka kwispool efunekayo kwitotshi yokuwelda.Umthombo wobushushu we-arc yombane weDc, kodwa i-polarity kunye ne-TIG welding isetyenziselwa ngokuchaseneyo.Igesi yokukhusela ihluke kwaye ifuna ukujoyina i-argon gas ibe yi-1% oksijini ukuphucula ukuzinza kwe-arc.

I-MIG welding ingasetyenziselwa i-semi-automatic okanye i-welding ngokuzenzekelayo, uluhlu olubanzi lwezicelo.I-MIG yokuwelda inokuwelda izinto ezahlukeneyo, kodwa kwiminyaka yakutshanje ngenxa ye-carbon kunye ne-low-alloy steels, kwaye ngakumbi usebenzisa i-argon-rich hybrid GMAW welding, kwaye kunqabile ukuba kusetyenziswe ukuwelda kwegesi ecocekileyo, igesi ye-inert yensimbi, ke ngoko, ukuwelda kusetyenziswa ngokuqhelekileyo. yokuwelda i-aluminiyam, i-magnesium, ubhedu, i-titanium kunye ne-alloys yayo kunye nentsimbi engatyiwa.I-MIG yokuwelda inokuwelda ubuninzi obahlukeneyo bomsebenzi, kodwa imveliso yokwenyani iqhelekile ukuwelda ipleyiti ebhityileyo, efana nobukhulu beshiti obuyi-2mm ngezantsi usebenzisa ukuwelda kwegesi yentsimbi engasebenzi ngcono.Ukuwelda kwe-MIG kunokufikelela kulawulo olukrelekrele kuzo zonke iindawo zokuwelda.

I-MIG welding ineendlela ezizenzekelayo kunye ne-automatic.I-Automatic MIG welding iyasebenza kwimigaqo ye-longitudinal seam, i-girth kunye nesikhundla esithe tye se-welding;I-welding emfutshane ye-MIG ye-MIG isetyenziswa kakhulu kwi-welding ye-tack, i-weld discontinuous welding kunye nentloko ye-aluminiyam yesikhongozeli, i-joint joint pipe kunye nokuqinisa i-welding ye-welding.Kanye kunye nokwandiswa kwezicelo zokuwelda kwe-MIG, kuphela ngu-Ar okanye Nguye onzima ukuhlangabezana nesidingo segesi yokukhusela, ngaloo ndlela iphuhliswe kwigesi engasebenziyo ukujoyina inani elincinci leegesi ezisebenzayo ezifana ne-oksijeni, umxube wegesi ye-carbon dioxide njengegesi yokukhusela.Idla ngokubizwa ngokuba yi-melt reactive gas, welding okanye i-MAG.Kwisakhiwo se-welding yemveliso, ngakumbi kwi-alloy ephezulu kunye neentsimbi ezingenanto kunye ne-alloys yazo kwimveliso ye-welding, i-MIG ye-welding ithatha indawo ebaluleke kakhulu.
