Electrode ea ho tjheseletsa ea Tšepe ea Mocheso o Tlase
W707
GB/T E5015-G
AWS A5.5 E7015-G
Tlhaloso: W707 ke electrode ea tšepe e mocheso o tlase e nang le sekoahelo sa sodium se tlase sa haeterojene. Sebelisa DCEP (electrode ea hona joale e tobileng) 'me e ka kopanngoa libakeng tsohle. Tšepe e kentsoeng e ntse e na le matla a matle a ho thula ha -70°C.
Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa tšepe e mocheso o tlase joalo ka 2.5Ni.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % | Boleng ba tšusumetso (J) -70℃ |
| E tiiselitsoe | ≥490 | ≥390 | ≥22 | ≥27 |
Tekanyo ea haedrojene e hasaneng ea tšepe e bolokiloeng: ≤6.0mL/100g (mokhoa oa glycerin) kapa ≤10mL/100g (mokhoa oa mercury kapa chromatography ea khase)
Tlhahlobo ea X-ray: Kereiti ea I
Khoeli e khothaletsoang:
| (mm) Bophara ba molamu | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) ho tjheseletsa hona joale | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong oa 350℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Leka ho sebelisa matla a manyane ha o tjheseletsa, ho tjheseletsa ka mekhahlelo e mengata le ka mekhahlelo e mengata.
