NĀ PALAPALA:
He kūpono ia no ka hoʻopili ʻana i ka hao hina ikaika a me ka hao nodular, e like me ka cylinder, block engine, gear box, etc.
NĀ PĀLĀWAI:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
JIS Z3252 DFCNiFe
NA ANOAI:
ʻO AWS ENiFe-CI (Z408) ka mea hao hao me ka nickel iron alloy core a me ka hoʻohaʻahaʻa ikaika o ka uhi graphite.Hiki ke hoʻohana ʻia i ka AC a me DC kumu ʻelua, loaʻa ka arc paʻa, a maʻalahi ke hana.Loaʻa i ka electrode nā hiʻohiʻona o ka ikaika kiʻekiʻe, ka plasticity maikaʻi, ka hoʻonui laina laina haʻahaʻa a pēlā aku.ʻO ka pale ʻana o ka māwae no ka hao hina hina e like me ia no Z308, ʻoiai ʻoi aku ka nui o ka pale ʻana no ka hao nodular ma mua o ENi-CI (Z308).No ka hao hao me ka phosphorus kiʻekiʻe (0.2%P), he hopena maikaʻi nō hoʻi a ʻoi aku ka haʻahaʻa o kāna hana ʻoki ʻana ma mua o Z308 a me Z508.Hoʻohana ʻia ʻo Z408 i ke kuʻi ʻana o ka hao hina a me ka hao nodular no ka lumi
NĀ MEA:
Ma mua o ke kuʻi ʻana, pono e kālua ʻia nā electrodes no 1 hola me ka mahana o 150±10 ℃ ma mua o ka hoʻohana ʻana.
I ka wā e wili ai, pono ia e lawe i ka weld liiki a ʻaʻole pono ka lōʻihi o kēlā me kēia weld ma mua o 50mm.E hoʻomāmā i ka wahi hoʻoheheʻe me ka hāmare ma hope koke o ka wili ʻana i mea e hoʻopau ai i ke kaumaha a pale i nā māwae.
Hoʻokomo ʻia ka wela haʻahaʻa.
