I-ERNiFe-CI isetyenziselwa i-welding yentsimbi.Le ntsimbi yokuzalisa isetyenziswa kakhulu ukoleka imiqulu yentsimbi.Ikwasetyenziselwa ukulungisa iicastings.Ubushushu bangaphambili kunye ne-interpass ye-175ºC (350ºF) ubuncinci bucetyiswayo ngexesha le-welding, ngaphandle apho i-weld kunye neendawo ezichatshazelwe bubushushu zinokuvelisa iintanda.
I-Ni 55 (iklasi ye-AWS ayichazwanga) yi-55% ye-Nickel wire.Umxholo ophantsi we-Nickel wenza le ngxube ibe noqoqosho ngakumbi kune-Ni 99. Iidiphozithi ze-Weld zihlala zisebenza ngomatshini, kodwa phantsi kweemeko zokuxutywa okuphezulu, ii-welds zinokuba nzima kwaye kunzima ukuzisebenzisa.Ihlala isetyenziselwa ukulungisa ii-castings ezinamacandelo anzima okanye anzima.Xa kuthelekiswa ne-Ni 99, ii-welds ezenziwe nge-55 Ni zinamandla kwaye zine-ductile ngakumbi, kwaye zinyamezela ngakumbi kwi-phosphorous ekubunjweni.Ikwanayo ne-coefficient esezantsi yokwandisa kune-Ni 99, ekhokelela ekuqhekekeni okumbalwa komgca wokudibanisa.

I-Binary Nickel-Iron (Ni-Fe) kunye ne-Ni esekelwe kwii-alloys ze-welding eziyinkimbinkimbi zibonelelwa ngentonga ye-welding kunye neengcingo ngobude obuqhelekileyo okanye ubude ukuya kwisicelo sabathengi.Kwiimeko zenkonzo eqhelekileyo, ukwakheka kweekhemikhali ziyafumaneka kwimixholo eyahlukeneyo yeNi ngokweyona migangatho yaseMelika naseYurophu.
