Electrode ea ho Welding ea Nickel le Nickel
Ni307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Tlhaloso: Ni307-1 ke electrode e thehiloeng ho nickel e nang le hydrogen sodium e tlase e koahetsoeng. Sebelisa DCEP (electrode ea hona joale e tobileng e ntle). Kaha weld e na le Nb, tšepe e kentsoeng e na le plasticity e ntle le khanyetso ea mapetso.
Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa litšepe tse kopantsoeng tsa nickel-chromium-iron (tse kang UNS N06600, UNS N06601) le bokaholimo ba tšepe. E na le thepa e ntle ea ho tjheseletsa tšepe e sa tšoaneng. E ka boela ea sebelisoa mochesong oa ho sebetsa oa 980°C, empa ha mocheso o phahame ho feta 820°C, khanyetso ea oxidation le matla li tla fokotseha.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Tse ling |
| ≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % |
| E tiiselitsoe | ≥550 | ≥360 | ≥27 |
Khoeli e khothaletsoang:
| Bophara ba molamu (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Hona joale ho tjheseletsa (A) | 60 ~ 90 | 80 ~ 110 | 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.
