Tlhaloso: J607 ke electrode ea tšepe e matla e nang le motsoako o tlase e nang le sodium e tlase e koahetsoeng. Sebelisa DCEP (electrode ea motlakase o tobileng), 'me e ka kopanngoa libakeng tsohle.
Kopo: E sebedisetswa ho tjheseletsa dibopeho tsa tshepe e mahareng ya khabone le tse nang le motswako o tlase wa tshepe e matla a lekanang, jwalo ka Q420, jj.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
| C | Mn | Si | Mo | S | P |
| ≤0.12 | 1.25 ~ 1.75 | ≤0.60 | 0.25 ~ 0.45 | ≤0.035 | ≤0.035 |
Litšobotsi tsa mechini tsa tšepe e welded:
| Ntho ea teko | Matla a tšepe Mpa | Matla a tlhahiso Mpa | Ho lelefatsa % | Boleng ba tšusumetso (J) -30℃ |
| E tiiselitsoe | ≥590 | ≥490 | ≥15 | ≥27 |
| E lekiloe | 620 ~ 680 | ≥500 | 20 ~ 28 | ≥27 |
Tekanyo ea haedrojene e hasaneng ea tšepe e bolokiloeng: ≤4.0mL/100g (mokhoa oa glycerin)
Tlhahlobo ea X-ray: Kereiti ea I
Khoeli e khothaletsoang:

Tsebiso:
1. Electrode e lokela ho besoa hora e le 'ngoe mochesong oa 350℃ pele ho ts'ebetso ea ho tjheseletsa;
2. Ho bohlokoa ho hlwekisa mafome, sekala sa oli, metsi le litšila likarolong tsa ho tjheseletsa pele ho tjheseletsa;
3. Sebelisa ts'ebetso e khutšoanyane ea arc ha u tjheseletsa. Tsela e moqotetsane ea ho tjheseletsa e loketse.
