Hoʻohana ʻia ʻo ERNiFe-CI no ka hoʻopili ʻana i ka hao.Hoʻohana nui ʻia kēia metala hoʻopiha e uhi i nā ʻōwili hao.Hoʻohana ʻia ia no ka hoʻoponopono ʻana i nā castings.Manaʻo ʻia kahi mahana preheat a interpass ʻo 175ºC (350ºF) ka liʻiliʻi i ka wā wili, me ka ʻole o ka weld a me nā wahi i hoʻopilikia ʻia e hiki ke ulu i nā māwae.
ʻO Ni 55 (ʻAʻole i kuhikuhi ʻia ka papa AWS) he 55% Nickel uea.ʻO ka haʻahaʻa Nickel maʻiʻo e ʻoi aku ka maikaʻi o kēia alloy ma mua o ka Ni 99. ʻO nā waihona Weld maʻamau i hiki i ka mīkini, akā ma lalo o nā kūlana o ka hoʻohui kiʻekiʻe, hiki i nā welds ke lilo i paʻakikī a paʻakikī i ka mīkini.Hoʻohana pinepine ʻia no ka hoʻoponopono ʻana i nā pahu me nā ʻāpana kaumaha a mānoanoa paha.Ke hoʻohālikelike ʻia me Ni 99, ʻoi aku ka ikaika o nā welds i hana ʻia me 55 Ni, a ʻoi aku ka hoʻomanawanui o ka phosphorous i ka hoʻolei ʻana.Loaʻa iā ia ka helu haʻahaʻa o ka hoʻonui ʻana ma mua o Ni 99, e hopena i ka liʻiliʻi o nā laina laina fusion.
