Electrode ea ho Welding ea Nickel le Nickel
Ni327-6
GB/T ENi6620
AWS A5.11 ENiCrMo-6
Tlhaloso: Ni327 -6 ke electrode e thehiloeng ho nickel e nang le sekoahelo se tlase sa sodium sa haeterojene. Sebelisa DCEP (electrode ea hona joale e tobileng)positive). Tšepe e kentsoeng e na le polasetiki e ntle haholo, ho tiea le ho hanyetsa mapetso. Tšepe e kentsoeng e na le coefficient ea katoloso e otlolohileng e tšoanang le ea tšepe, 'me e na le matla a phahameng le ho hanyetsa ho bola ho matla mochesong oa kamore le mochesong o phahameng.
Tšebeliso: E sebelisetsoa ho tjheseletsa tšepe ea Ni9%, 'me e ka boela ea sebelisoa bakeng sa ho tjheseletsa litšepe tse fapaneng le li-alloy tse thata ho tjheseletsa.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Tse ling |

Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % |
| E tiiselitsoe | ≥620 | ≥350 | ≥32 |
Khoeli e khothaletsoang:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 |
| Hona joale ho tjheseletsa (A) | 50 ~ 70 | 80 ~ 100 | 110 ~ 150 |
Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong o ka bang 300℃ pele ho ts'ebetso ea ho tjheseletsa. Leka ho sebelisa arc e khutšoanyane ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa.
3. Leka ho sebelisa matla a manyane ha o tjheseletsa, ho tjheseletsa ka mekhahlelo e mengata le ka mekhahlelo e mengata.
