ERNiFe-CI yog siv rau vuam ntawm cam khwb cia hlau.Cov hlau muab tub lim no feem ntau ua haujlwm los muab cov cam khwb cia hlau yob.Nws kuj yog siv los kho cov castings.Ib qho preheat thiab interpass kub ntawm 175ºC (350ºF) yam tsawg kawg nkaus yog pom zoo thaum lub sij hawm vuam, yam tsis muaj qhov vuam thiab kub cuam tshuam cheeb tsam tuaj yeem tsim cov kab nrib pleb.
Ni 55 (AWS class notified) is a nominally 55% Nickel wire.Cov ntsiab lus qis nickel ua rau cov alloy no txuag nyiaj ntau dua Ni 99. Weld deposits feem ntau yog siv tshuab, tab sis nyob rau hauv tej yam kev mob siab admixture, cov welds tuaj yeem nyuaj thiab nyuaj rau tshuab.Nws yog feem ntau siv los kho cov castings nrog hnyav lossis tuab.Raws li piv rau Ni 99, welds ua nrog 55 Ni muaj zog dua thiab ntau dua, thiab ntau dua ntawm phosphorous nyob rau hauv casting.Nws kuj tseem muaj qis dua coefficient ntawm kev nthuav dav dua Ni 99, uas ua rau tsawg dua fusion kab tawg.

Binary Nickel-Iron (Ni-Fe) thiab Ni raws li txoj hlua vuam hlau yog muab rau hauv vuam pas nrig thiab cov xov hlau nyob rau hauv tus qauv ntev lossis ntev mus txog rau cov neeg siv khoom thov.Rau cov kev pabcuam ib txwm muaj, cov tshuaj muaj pes tsawg leeg muaj nyob hauv ntau cov ntsiab lus Ni raws li feem ntau ntawm Asmeskas thiab European cov qauv.
