Electrode ea ho Welding ea Nickel le Nickel
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Tlhaloso: Ni202 ke electrode ea motsoako oa Ni70Cu30 Monel e nang le sekoahelo sa titanium calcium. E ka sebelisoa bakeng sa AC le DC. Tšepe e kentsoeng e na le khanyetso e ntle ea mapetso ka lebaka la dikahare tse loketseng tsa manganese le niobium. E na le ts'ebetso e ntle ea ho tjheseletsa ka ho cha ha arc e tsitsitseng, ho fafatsa ho fokolang, ho tlosa slag habonolo, le ho tjheseletsa ho hotle.
Tšebeliso: E sebelisetsoa ho tjheseletsa motsoako oa nickel-copper le tšepe e fapaneng, 'me e ka boela ea sebelisoa e le thepa ea phetoho e koahelang.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % |
| E tiiselitsoe | ≥480 | ≥200 | ≥27 |
Khoeli e khothaletsoang:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 |
| Hona joale ho tjheseletsa (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong o ka bang 250℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa.
