Tlhaloso: Ni307-3 kenikeliElectrode e thehiloeng ho eona e nang le sekoahelo sa sodium se nang le haeterojene e tlase. Sebelisa DCEP (electrode ea hona joale e tobileng e ntle). E na le khanyetso e ntle ea mapetso hobane weld e na le karolo e itseng ea manganese, niobium, le likarolo tse ling tsa alloying.
Kopo: E sebelisoa bakeng sa ho tjheseletsanikeli-li-alloy tsa chromium-tšepe (tse kang UNS N06600) le bokaholimo ba tšepe. Mocheso o sebetsang ka kakaretso ha o phahame ho feta 480 ° C, 'me khanyetso ea mapetso e ntle. E loketse sejana sa khatello ea sebōpi sa athomo le ho tjheseletsa tanka ea lik'hemik'hale.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):

| Hona joale ho tjheseletsa (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong o ka bang 300℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, oli, metsi le litšila likarolong tsa ho tjheseletsa pele o tjheseletsa. Leka ho sebelisa arc e kgutshwane ho tjheseletsa.
