Description: T207 ne jan karfe gami lantarki da silicon tagulla core da low hydrogen sodium shafi.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye) tare da manyan kaddarorin inji.Yana da kyau juriya ga inorganic acid ban da nitric acid, mafi yawan kwayoyin acid da ruwan teku.
Aikace-aikace: Ya dace da walda na jan karfe, tagulla silicon da tagulla, walƙiya walƙiya na rufin bututun kayan aikin sinadarai, da sauransu.
Abubuwan sinadaran na weld karfe(%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| 92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Abubuwan kayan aikin walda:
| 试验项目 Gwaji abu | 抗拉强度 Ƙarfin ƙarfi Mpa | 延伸率 Tsawaitawa % |
| 保证值 Garanti | ≥270 | ≥20 |
Shawarwari na yanzu:
| Diamita na sanda (mm) da | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Sanarwa:
Matakan kariya:
1. Dole ne a gasa wutar lantarki a kimanin 300 ° C na 1 zuwa 2 hours kafin walda;
2. Dole ne a cire danshi, mai, oxides da sauran datti a saman walda kafin waldawa.
3. Lokacin walda silicon tagulla ko surfacing waldi a kan karfe, babu preheating da ake bukata.Matsakaicin zafin jiki don walda tsantsar jan ƙarfe yana da kusan 450 ° C, kuma zafin zafin da ake buƙata don waldawar tagulla yana kusan 300 ° C;
4. Ya kamata a yi amfani da walda na gajere lokacin walda.A lokacin waldawar multilayer, slag tsakanin yadudduka dole ne ya kasance
gaba daya cire;bayan walda, guduma walda tare da lebur kai guduma don tace hatsi, kawar da damuwa, da kuma inganta ƙarfi da kuma robobi na walda.
