Ii-electrode zokuwelda ze-nickel alloyimele udidi olukhethekileyo lweentsimbi zokuzalisa ezenzelwe ukudibanisa nokulungisa izixhobo ezinzima, ikakhulu isinyithi esityhidiweyo. Udidi lwe-AWS A5.15 ENi-C1, oluboniswe ziimveliso ze-Z208, luchaza uhlobo oluthile lwezi electrodes. Olu didi luthile lwee-electrodes zokuwelda ze-nickel alloy lunesiseko sentsimbi esezantsi yekhabhoni kunye nengubo etyebileyo kwi-graphite, evumela ukusetyenziswa kwazo kunye nemithombo yamandla ye-AC kunye ne-DC ukuze kube lula kwiindawo ezahlukeneyo zokusebenza.
Umgaqo wokusebenza kolu hlobo lwee-electrode ze-nickel alloy welding ugxile ekudluliseleni kwezinto ezidibanisa i-alloying kwisinyithi se-weld. Umxholo ophezulu we-graphite kwi-coating ukhuthaza ukwakheka kwesakhiwo esigcwele i-carbon. Xa i-weldment iphantsi kwenkqubo yokupholisa elawulwayo necothayo, idiphozithi ephumayo iyaqina njengesakhiwo se-gray cast iron microstructure. Oku kubonelela ngokuhambelana okuhle kwe-metallurgical kwizixhobo ezilungiswayo, nto leyo ebalulekileyo ukuze kuhambelane.
Uphawu oluphawulekayo lobugcisa lweziii-electrode zokuwelda ze-nickel alloyyimeko yokumelana nokuqhekeka okuphantsi kwesinyithi esijijekileyo. Le nkunkuma, nangona ihambelana nesinyithi esingwevu kwisakhiwo sayo, ifumana ubuqhophololo bayo kunye nokuguquguquka okulinganiselweyo. Oku kwenza indawo yokujijela ibe sesichengeni sokuqhekeka ngenxa yoxinzelelo lobushushu olubangelwa ngexesha lokupholisa. Ngenxa yoko, ukusetyenziswa ngempumelelo kufuna ukuthotyelwa ngokungqongqo kokufudumeza kwangaphambili icandelo lesinyithi esijijekileyo kunye nokusebenzisa ukupholisa okucothayo kakhulu, okulawulwayo emva kokujijelwa ukuze kuncitshiswe i-gradients yobushushu kunye noxinzelelo.
Eyona ndlela iphambili yokusebenzisa ii-electrode ezihlelwe yi-ENi-C1 kukulungisa iziphene kwi-grey cast iron castings. Oku kuquka ukulungisa iziphene ze-shrinkage cages, imingxuma yesanti, kunye neentanda ezivela kwinkqubo yokwenziwa okanye ezenzeka ngexesha lokulungiswa. Ukusetyenziswa kwazo ngokubanzi kugxile ekubuyiseleni i-geometry kunye nomsebenzi wezinto ezingathwali imithwalo ephezulu yamandla okanye uxinzelelo lwempembelelo.
Inkcazo ye-ENi-C1 ibonisa iqela elithile leii-electrode zokuwelda ze-nickel alloyzenzelwe ukuphinda zisetyenziswe ngentsimbi ephosweyo. Ixabiso lazo lisekuveliseni idiphozithi yokuwelda ehambelana nesinyithi, kodwa oku kulungelelaniswa yimfuneko yolawulo olucokisekileyo lobushushu ngexesha lenkqubo yokuwelda ukuze kuthintelwe ukunqongophala kwazo kokuxhathisa okungalunganga kokuqhekeka.
