Xa usebenzisa ii-electrode zokuwelda i-arc, umatshini wokuwelda ofunekayo ulula, kwaye ungakhetha umatshini wokuwelda we-AC okanye we-DC. Ukongeza, akukho mfuneko yezixhobo ezincedisayo ezigqithisileyo xa uwelda, logama nje kukho izixhobo ezilula ezincedisayo. Ezi matshini zokuwelda zilula ngesakhiwo, zixabiso liphantsi, kwaye kulula ukuzigcina zisemgangathweni. Ngenxa yotyalo-mali oluphantsi ekuthengeni izixhobo, ukuwelda i-electrode arc kuye kwasetyenziswa kakhulu kwimveliso yemizi-mveliso.
Itekhnoloji yokuwelda i-electrode arc ayinamsebenzi wokugcwalisa isinyithi kwi-weldment kuphela, kodwa ayidingi nokufaka igesi eyongezelelweyo yokukhusela ngexesha lokusetyenziswa. Ngexesha lokufudumeza i-arc, umbane phakathi kwe-electrode kunye ne-weldment udala ichibi elinyibilikisiweyo, ngelixa i-electrode ngokwayo ivelisa iimveliso zokutsha ezisebenzisanayo ukwenza igesi yokukhusela ekhusela ichibi elinyibilikisiweyo kunye ne-weld. Ukongeza, ulwakhiwo lwentonga yokukhusela luyilwe ukuba lukwazi ukumelana nomoya kakhulu kwaye lube namandla ekuchaseni umoya, nto leyo evumela ukuwelda okusemgangathweni ophezulu kwindawo enomoya.
I-arc ye-electrodeukuweldaineengenelo zokusebenza okulula kunye noluhlu olubanzi lwezicelo. Ifanelekile ukuwelda inani elincinci leemveliso okanye iibhetshi ezincinci, ingakumbi ezo welds kunzima ukuziwelda ngoomatshini abanjengeemilo ezingaqhelekanga kunye nobude obufutshane. Xa usebenzisa iteknoloji yokuwelda ye-arc ye-stick arc, indawo yokuwelda ayithintelwanga, kwaye ingasetyenziswa ngokulula nakwiindawo ezimxinwa okanye kwiindawo ezinzima. Ukongeza, izixhobo ezifunekayo kwiteknoloji yokuwelda ye-arc ye-electrode zilula, akukho gesi yokuncedisa esetyenziswayo, kwaye inqanaba lesakhono somsebenzisi aliphezulu kakhulu.
Ukusetyenziswa kwetekhnoloji yokuwelda ye-electrode arc kubanzi kakhulu, kwaye kufanelekile ukuwelda phantse zonke iintsimbi ezisemgangathweni kunye nee-alloys. Ngokukhetha i-electrode echanekileyo, ukuwelda kunokufezekiswa kwizixhobo ezahlukeneyo, kubandakanya intsimbi e-alloy ephantsi, intsimbi yekhabhoni, intsimbi ye-alloy ephezulu kunye neentsimbi ezahlukeneyo ezingezizo i-ferrous. Ukongeza, ii-electrode zingasetyenziselwa ukuwelda iintlobo ezahlukeneyo zezinto zokusebenza, ezifana neentsimbi ezahlukeneyo, kunye nemisebenzi eyahlukeneyo yokuwelda efana nokulungisa ukuwelda kwesinyithi esityhidiweyo kunye nokuwelda okungaphezulu kwezinto ezahlukeneyo zesinyithi. I-electrode ngokwayo inokubonelela ngegesi ethile yokukhusela ukuze kuthintelwe iingxaki ezifana nokuxinana kwe-weld. Kwangaxeshanye, isinyithi esizalisayo sinokunyusa amandla kunye nokuqina kwe-weld. Kwiimeko ezinzima ezifana nemimoya enamandla, itekhnoloji yokuwelda ye-electrode arc nayo inokugcina iziphumo ezilungileyo, iqinisekisa umgangatho kunye nokusebenza kakuhle kwemisebenzi yokuwelda.
Inkqubo yokuhlanganisa imiselwa ngokweempawu zezinto zesinyithi, kwaye izinto ezahlukeneyo zesinyithi zifuna iindlela zokuhlanganisa ezihambelanayo. Ngokubanzi, intsimbi yekhabhoni, intsimbi ye-alloy ephantsi, intsimbi engatyiwayo, intsimbi engatshiyo, intsimbi engatshiyo, intsimbi engatshiyo, ubhedu kunye nee-alloys zazo zinokudityaniswa ngeendlela zokuhlanganisa eziqhelekileyo. Nangona kunjalo, kwezinye izinto zesinyithi, ezifana nesinyithi esityhidiweyo, intsimbi enamandla aphezulu kunye nentsimbi eqinileyo, unyango lokufudumeza kwangaphambili okanye emva kobushushu lunokufuneka, okanye iindlela zokuhlanganisa ezixutyiweyo zingasetyenziswa. Nangona kunjalo, iintsimbi ezine-low melting point (ezifana ne-zinc, i-lead, i-tin kunye nee-alloys zazo) kunye neentsimbi ezichaseneyo (ezifana ne-titanium, i-niobium, i-zirconium, njl.njl.) azinakudityaniswa kusetyenziswa iinkqubo zokuhlanganisa eziqhelekileyo. Ke ngoko, ngaphambi kokuhlanganisa, kuyimfuneko ukuhlalutya ngononophelo nokuvavanya izinto, kwaye ukhethe iteknoloji efanelekileyo yokuhlanganisa kunye nenkqubo ngokwemeko yokwenyani.
Iimveliso ezinjalo zihlala zinezakhiwo ezintsonkothileyo kunye neemilo ezahlukeneyo, ezifuna imisebenzi eyenziwa ngesandla kunye neenkqubo zokuwelda ezibuthathaka ukuqinisekisa umgangatho kunye nokuthembeka kokuwelda. Ekubeni inkqubo yokuwelda ifuna izakhono zobungcali kunye namava, iindlela zokuvelisa ezisebenzisa oomatshini nezizenzekelayo azifanelekanga kolu hlobo lwemveliso. Kwangaxeshanye, olu hlobo lwemveliso ludla ngokuba nexabiso eliphezulu leyunithi okanye iqela elincinci lemveliso, kwaye kufuneka lenziwe ngendlela ejolise kuyo. Ke ngoko, kolu hlobo lwemveliso, indlela efanelekileyo yemveliso kukuwelda ngesandla kunye nemveliso encinci ukuqinisekisa umgangatho kunye nokusebenza kakuhle kwemveliso. Kwangaxeshanye, itekhnoloji yobungcali kunye namava ayafuneka ekufakweni nasekugcinweni ukuqinisekisa ukusetyenziswa okuqhelekileyo kunye nokhuseleko lwemveliso.
