Maelectrode ekuwedera eNickel alloyinomiririra chikamu chakakosha chesimbi dzekuzadza dzakagadzirirwa kubatanidza nekugadzirisa zvinhu zvakaoma, kunyanya simbi yakakandwa. Kurongwa kweAWS A5.15 ENi-C1, kunoratidzwa nezvigadzirwa Z208, kunotsanangura rudzi rwakasiyana rwemaelectrode aya. Rudzi urwu rwemaelectrode ekubatanidza nickel alloy ane simbi ine kabhoni shoma uye girafu yakapfuma mugrafiti, zvichiita kuti ashandiswe nemagetsi eAC neDC kuti akwanise kuchinjika munzvimbo dzakasiyana dzekushanda.
Nheyo yekushanda kwemhando iyi ye nickel alloy welding electrodes inonyanya kuenderana nekutamiswa kwezvinhu zvinosanganisa simbi inosanganisa simbi. Graphite yakawanda iri mu coating inokurudzira kuumbwa kwechimiro chakazara nekabhoni. Kana weldment ikaiswa muitiro wekutonhodza unodzorwa, unononoka, deposit inoguma yaoma se grey cast iron microstructure. Izvi zvinopa metallurgical match yakanaka kune base material iri kugadziriswa, izvo zvakakosha kuti ienderane.
Hunhu hunozivikanwa hwehunyanzvi hweizvimaerekitirodhi ekuwedhesa enickel alloyisimba rakaderera rekudzivirira kuputika kwesimbi ye weld. Nzvimbo iyi, kunyange zvazvo ichienderana nesimbi yegrey muchimiro, inogara nhaka kuputsika kwayo uye kugona kwayo kushoma. Izvi zvinoita kuti nzvimbo ye weld ive nyore kutsemuka nekuda kwekumanikidzwa kwekupisa kunokonzerwa nekutonhora. Nekuda kweizvozvo, kushandisa zvakanaka kunoda kunyatsotevedzera kupisa kwechikamu chesimbi ye cast uye kushandisa kutonhora kunononoka, kunodzorwa mushure mekukweva kuti kuderedzwa kwekupisa uye kushushikana.
Chinonyanya kushandiswa pakugadzira maelectrode e-ENi-C1 classified kugadzirisa zvikanganiso zviri mu grey cast iron castings. Izvi zvinosanganisira kugadzirisa zvikanganiso zvinokanganisa shrinkage cages, jecha maburi, uye mitswe inobva mukugadzirwa kana kuitika panguva yekushanda. Kushandiswa kwavo kunowanzo tarisa pakudzoreredza geometry uye mashandiro ezvikamu zvisingatapurirwe nemitoro yakawanda kana kumanikidzwa.
Tsanangudzo yeENi-C1 inoreva boka rakati remaerekitirodhi ekuwedhesa enickel alloydzakagadzirirwa kugadzirisa simbi yakakandwa. Kukosha kwadzo kuri mukugadzira weld deposit inoenderana nesimbi, asi izvi zvinoenzaniswa nechinodiwa chekutarisira kupisa kwakanyatsonaka panguva yekushongedza kuti dzidzivirire miganhu yadzo yekusagadzikana kwekuputika.
