I-GB/T EZNiCu-1 (Z508) yi-electrode yokuwelda eyenziwe ngokukodwa eyenzelwe ukulungiswa kunye nokubuyiselwa kwezinto zesinyithi esityhidiweyo. Uhlu lwayo phantsi kwe-Chinese National Standard GB/T lubonisa ukunamathela kwayo kwiimfuno zobugcisa ezichanekileyo, ukuqinisekisa ukusebenza okuzinzileyo kunye nolawulo lomgangatho. Olu hlobo lwe-electrode lwenzelwe ukufaka umaleko we-alloy ekhethekileyo kwizinto ezisisiseko, okwenza kube yinto efunekayo kwimisebenzi yolondolozo kunye nokulungisa kumashishini ahlukeneyo anzima apho kufuneka khona ukubuyiselwa kweendawo zesinyithi esityhidiweyo.
Uphawu oluchaza okui-electrode yokuwelda ephezu komhlabayintambo yayo engundoqo, eyenziwe yi-alloy ye-nickel-copper, eyaziwa ngokuba yiMonel. Le nto ingundoqo ibalulekile ekusebenzeni kwe-electrode, njengoko ivelisa idiphozithi ye-weld enomatshini ogqwesileyo kunye ne-thermal expansion coefficient ehambelana kakhulu neye-cast iron. Oku kuhambelana kubalulekile ekunciphiseni uxinzelelo lwe-welding kunye nokuthintela ukwakheka kweentanda, eziyimingeni eqhelekileyo enxulumene ne-cast iron welding, ngaloo ndlela kuqinisekiswa ukuthembeka kokulungiswa.
Ukusebenza kwe-electrode kuphuculiswa ngakumbi yi-graphitized flux coating yayo. Le coating isebenza ngeenjongo ezininzi ezibalulekileyo ngexesha lenkqubo yokudibanisa: inika uzinzo lwe-arc, ivelisa iigesi ezikhuselayo ukukhusela ichibi elinyibilikisiweyo ekungcolisweni komoya, kwaye yenza isigqubuthelo se-slag ukunceda ekuqineni okulawulwayo kwesinyithi se-weld. Ii-graphitizing agents ezikwi-coating zikhuthaza ukuna kwe-graphite kwisinyithi se-weld, nto leyo ephucula kakhulu ukusebenza kwe-machinability kwaye inceda ukufezekisa isakhiwo se-metallurgical esifanelekileyo esifana nesinyithi esisisiseko.
Isicelo esiphambili sale nto ikhethekileyoi-electrode yokuwelda ephezu komhlabakukulungiswa kweziphene kwi-grey kunye ne-nodular cast iron castings. Isebenza ngakumbi kwimisebenzi efana nokugcwalisa iintanda, ukulungisa iimpazamo zoomatshini, kunye nokwakha kwakhona iindawo ezigugileyo apho kufuneka khona umatshini wokulungisa emva kokuwelda. Ukuthembeka kwayo kuyenza ibe sisixhobo esibalulekileyo kumacandelo afana nokuvelisa iimoto, ubunjineli baselwandle, kunye nokulungisa izixhobo ezinzima, apho inegalelo ekwandiseni ubomi benkonzo yezinto ezibalulekileyo.
I-GB/T EZNiCu-1 (Z508)i-electrode yokuwelda ephezu komhlabayimveliso esetyenziswayo ephucukileyo ngokwetekhnoloji eyenzelwe ukujongana nobunzima obuthile bokuwelda ngentsimbi ephothiweyo. Indibaniselwano edibeneyo ye-Monel alloy core yayo kunye ne-graphitized flux coating ibonelela ngesisombululo esomeleleyo sokufezekisa iileya zomphezulu ezikumgangatho ophezulu, ezisebenza ngomatshini, nezingenaqhekeko. Kwiingcali ezibandakanyeka ekugcinweni nasekulungisweni kwentsimbi ephothiweyo, le electrode inika ukhetho oluthembekileyo nolufanelekileyo kwetekhnoloji.
