Yesiqheloumbhobho weoyilei-welding, umgangatho unzima ukulawula kwaye unzima ukufezekisa i-slag ye-welding efunekayo ayivumelekanga ngaphakathi, nangona kunjalo, ukuxhaswa kwe-welding esebenzayo ngakumbi kwaye isetyenziswe ngokubanzi, indlela ye-arc ye-welding manual yokugubungela.Ngale ndlela i-arc ecacileyo, i-welding operation ilula, i-pores ephantsi, i-slag, ukungena okungaphelelanga kunye nezinye iziphene ze-weld emva, okwangoku, ngenxa yomthamo omncinci womgca, ngoko ke indawo encinci echaphazelekayo yokushisa, i-deformation encinci kunye nokuthambekela kokuqhekeka.

I-Tungsten inert yegesi yokuwelda isifinyezo TIG (Tungsten Inert Gas Weiding) welding.Kuphantsi kokukhuselwa kwegesi ye-inert, ukusetyenziswa kwe-arc ye-tungsten eyenziwa yi-electrode kunye nesiseko se-workpiece kunye ne-hot melt filler wire (i-filler wire ukuba isetyenziswe) yindlela ye-welding.Irhasi eqhubekayo yokukhusela i-welding ekhutshwe kwi-nozzle yetotshi, i-arc yenziwe malunga nomgangatho okhuselayo wedwa kwigesi yomoya, ukuthintela impembelelo enobungozi kakhulu kwindawo echaphazelekayo yokushisa kwe-tungsten ejikeleze i-weld pool, evumela ukuba i-welds yomgangatho ophezulu.

Izibonelelo ze-TIG zokuwelda:

I-1) i-TIG ye-welding inokuthi idibanise isinyithi kunye nokunye, indawo ye-argon ye-welding inokutshatyalaliswa ngokufanelekileyo emoyeni ojikelezileyo, ayinyibiliki isinyithi, kwaye isinyithi asiyi kusabela.Inkqubo ye-TIG ye-welding, i-arc welding kunye nefilimu ye-oxide ye-automatic.Ngoko ke, impumelelo yezinye iindlela welding lula oxidized ngokulula welded, nitriding, chemical reactivity kunye nentsimbi non-intsimbi eyomeleleyo, stainless steel kunye nengxubevange ezahlukeneyo.

2) umphumo wokukhusela, umgangatho ophezulu we-weld.I-Ar yenye yezona zinto zizinzileyo kunye negesi ye-inert engaphenduliyo kunye ne-metal reaction, i-soluble kwintsimbi engamanzi ayivelisi i-pores, ngoko ke intsebenzo yokukhusela egqwesileyo.Inkqubo ye-welding yinkqubo elula yokunyibilika kwesinyithi kunye ne-crystallization, kwaye ngoko umgangatho ophezulu we-weld.

3) Ngenxa yokunyanzeliswa kunye nokupholisa kwe-arc ngokuhamba kwe-argon, uxinzelelo lwe-welding kunye ne-deformation encinci, i-arc yoxinzelelo lobushushu kunye ne-argon yokushisa ephezulu, inokuqinisekisa ukuba ukungena kweengcambu ze-weld, iindawo ezincinci ezichaphazelekayo zokushisa, i-welding deformation encinci. kunye notyekelo lokuqhekeka .Ngokukodwa kwimikhwa yokucima umoya yentsimbi edityanisiweyo.

I-4) ukuzinza kwe-arc ye-tungsten, nakwi-welding current encinci (<10A) isephantsi kokutsha okuzinzileyo, ngokukodwa kwizinto ezincinci, ezinqabileyo ze-welding plate.

5) ubushushu kunye nocingo lokuzalisa lunokulawulwa, kwaye ngoko ke kulula ukuhlengahlengisa igalelo lobushushu linokudityaniswa kwiindawo ezahlukeneyo, kodwa kunye nendlela efanelekileyo yokufezekisa i-welding yecala eliqhakazile.

6) Njengoko ucingo lokuzalisa aludluli kwi-arc, aluvelisi i-spatter, ukubonakala kwe-weld.

I-7) I-Ar igesi ye-athomu enye, umthamo omncinci wokushisa, ukusebenza kakuhle kwe-thermal, ukusetyenziswa kobushushu, ukutshiswa okuzinzileyo kwe-arc kunenzuzo kakhulu, nakwiimeko eziphantsi zangoku kunye ne-arc ende, i-arc ihlala izinzile, kulula ukuyisebenzisa, kulula ukuyisebenzisa. ukulawula umgangatho weld imikhondo nzima umbhobho ukuwelda isikhundla zonke-indawo ukuwelda.

I-TIG welding kulula ukuyisebenzisa ngenxa yomgangatho omhle, kwiminyaka yakutshanje, ibe yindlela eqhelekileyo kwiinkampani zokuvelisa amandla ekufakeni nasekugcinweni kwebhoyila yokufudumeza iityhubhu ezidityanisiweyo.Ngaphantsi kweemeko zokugcinwa kwendawo, kunye nokusebenza kwendawo ye-welding ngokuthintelwa kwendawo, indlela yenkqubo esetyenziswa ngokuqhelekileyo i-TIG welding SMAW igubungela ubuso bonke okanye ukusetyenziswa kwe-TIG welding.
