Iintambo zokuWelda zeStick zizixhobo ezisisiseko ekuwelding ngesandla kwe-arc yesinyithi, apho udidi lwe-AWS E7018 lumele olunye lwezona ntlobo zisebenziseka lula nezisetyenziswa kakhulu. Le electrode ithile, eyaziwa ngokuba yi-J506Fe ngokwemigangatho yesizwe, luhlobo lomgubo wesinyithi we-potassium ophantsi. Ukwenziwa kwayo kwenzelwe ukuvelisa ii-welds ezikumgangatho ophezulu, ezinamandla nezineziphene ezincinci, nto leyo eyenza ukuba ibe lukhetho olukhethwayo kwimisebenzi eyahlukeneyo yokwenza nokulungisa, ukusuka kumsebenzi wesinyithi wesakhiwo ukuya kulondolozo loomatshini abanzima.
Uphawu oluphambili lwezi zintoIzintonga zokuWelda zeNtongayingubo yabo yentsimbi engenahydrogen iron powder. Olu lwakhiwo lubalulekile ekunciphiseni umswakama onokubangela ukuqhekeka kwe-hydrogen kwisinyithi esinobuqhophololo, ingakumbi kwiintsimbi ezinamandla aphezulu okanye kwiindawo ezixineneyo. Ukufakwa komgubo wentsimbi kwandisa ukusebenza kakuhle kokufakwa, okuvumela ukuba kufakwe isinyithi esinobuqhophololo kwinduku enye xa kuthelekiswa neentlobo zepowder ezingezizo zentsimbi. Oku kuphucula imveliso ngelixa kugcinwa ukuthembeka kwe-weld okugqwesileyo.
Inzuzo ebalulekileyo yokusebenza kwe-E7018Izintonga zokuWelda zeNtongayindlela ezisebenza ngayo ngokuguquguqukayo kwiindawo zokuwelda. Zenzelwe ukusetyenziswa kuzo zonke iindawo ezithe tyaba, ezithe tye, ezithe nkqo, nezingaphezulu，ukubonelela abawelda ngokuguquguquka kokujongana neeprojekthi ezinzima ngaphandle kokutshintsha izinto ezisetyenziswayo. Basebenza ngokufanelekileyo kwimithombo yamandla ye-Alternating Current (AC) kunye ne-Direct Current (DC). Oku kuhambelana okubini kuqinisekisa ukuba bangasetyenziswa phantse nayo nayiphi na imashini yokuwelda eqhelekileyo, ukusuka kwiirigi zoshishino ukuya kwiijenereyitha zendawo eziphathwayo.
Iidiphozithi ze-weld ezivela kwezi electrodes zaziwa ngeempawu zazo eziphezulu zoomatshini kunye nembonakalo ebonakalayo. I-weld bead idla ngokuba bushelelezi, ine-ripple encinci kunye ne-slag elula ukuyisusa. Okubaluleke ngakumbi, isinyithi se-weld sibonisa ukuqina okuphezulu, nokuba kumaqondo obushushu aphantsi, kwaye sinikezela ngamandla amahle okutsalwa. Olu dibaniso lomgangatho wobuhle kunye nokuthembeka koomatshini kwenza ezi ntonga zilungele ukusetyenziswa okubalulekileyo apho ukusebenza kwe-weld kungaxoxiswana ngako.
Udidi lwe-AWS E7018 (J506Fe) lumele udidi lweIzintonga zokuWelda zeNtongaokulinganisela ukuguquguquka kokusebenza kunye neziphumo eziqinileyo. Ubuchule bazo bokusebenza kuzo zonke iindawo, ukuhambelana kwazo ne-AC kunye ne-DC, kunye neempawu zazo ze-hydrogen ephantsi, ezinokufakwa okuphezulu zizenza zibe zizinto eziyimfuneko kakhulu kwiindawo ezininzi zokusebenzela nakwiindawo zokwakha. Kubawelda abafuna i-electrode ethembekileyo, enenjongo ngokubanzi yokusetyenziswa okungafunekiyo, olu hlobo lwentonga yokweluka intonga luhlala lukhetho oluthembekileyo rhoqo.
