IZICELO:
Ilungele ukushiselwa kwensimbi empunga enamandla kanye nensimbi eyi-nodular cast, njengesilinda, ibhulokhi yenjini, ibhokisi legiya, njll.
IMIGAQO:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
I-JIS Z3252 DFCNiFe
IZIMPAWU:
I-AWS ENiFe-CI (Z408) iyi-electrode yensimbi eyinsimbi enomgogodla we-nickel iron alloy kanye nokwehliswa okuqinile kokunamathela kwegraphite.Ingasetshenziswa ngezinhloso ezimbili ze-AC ne-DC, ine-arc ezinzile, futhi kulula ukuyisebenzisa.I-electrode inezici zamandla aphezulu, i-plasticity enhle, i-coefficient ephansi yokunwetshwa komugqa nokunye.Ukumelana nokuqhekeka kwensimbi empunga kufana nalokho kwe-Z308, kuyilapho ukumelana nokuqhekeka kwe-nodular cast iron kungaphezu kwe-ENi-CI (Z308).Ngensimbi ekhonjiwe ene-phosphorus ephezulu (0.2%P), nayo inemiphumela emihle futhi ukusebenza kwayo kokusika kungaphansi kwe-Z308 kanye ne-Z508 kancane.I-Z408 isetshenziswa ekushiseleni insimbi empunga kanye ne-nodular cast iron njengegumbi
QAPHELA:
Ngaphambi kokushisela, ama-electrode adinga ukubhakwa ihora elingu-1 ngezinga lokushisa elingu-150±10℃ ngaphambi kokuwasebenzisa.
Uma ushisela, kufanelekile ukuthatha i-weld encane futhi ubude be-weld ngayinye akufanele budlule u-50mm.Hammer indawo yokushisela kancane ngesando ngokushesha ngemva kokushisela ukuze uqede ukucindezeleka futhi uvimbele imifantu.
Okokufaka okuphansi kokushisa kuyanconywa.

Izici Zokusetshenziswa:
I-arc ezinzile kakhulu.
Ukususwa okuhle kakhulu kwe-slag.
Ukungena akujulile.
Ukushisa okuhle nokumelana nokugqwala.
Ukumelana nokuqhekeka okuhle kakhulu.
