Nickel da Nickel Alloy Welding Electrode
Ni307-3
GB/T ENi6182
AWS A5.11 ENiCrFe-3
Bayani: Ni307-3nickel- tushen electrode tare da low-hydrogen sodium shafi.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye).Yana da juriya mai kyau saboda walda yana ƙunshe da adadin manganese, niobium, da sauran abubuwa masu haɗawa.
Application: Ana amfani da walda nanickel-chromium-iron alloys (kamar UNS N06600) da kuma surfacing na karfe.Yawan zafin jiki na aiki gabaɗaya baya sama da 480 ° C, kuma juriya na tsaga yana da kyau.Dace da atomic makera matsa lamba jirgin ruwa da sinadaran tanki waldi.
Abubuwan sinadaran na weld karfe(%):
| C | Mn | Fe | P | S | Si | Cu |
| ≤0.10 | 5.0 ~ 10.0 | ≤10.0 | ≤0.020 | ≤0.015 | ≤1.0 | ≤0.5 |
| Ni | Ti | Mo | Nb | Ta | Sauran |
|
| ≥ 60.0 | ≤1.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | ≤0.30 | ≤0.50 |
|
Abubuwan kayan aikin walda:
| Gwaji abu | Ƙarfin ƙarfi Mpa | Ƙarfin bayarwa Mpa | Tsawaitawa % |
| Garanti | ≥550 | ≥360 | ≥27 |
Shawarwari na yanzu:
| Diamita na sanda (mm) da | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding halin yanzu (A) | 60 ~ 90 | 80 ~ 100 | 110 ~ 150 | 130 ~ 180 |
Sanarwa:
1. A lantarki dole ne a gasa for1 hour a kusa da 300 ℃ kafin walda aiki;
2. Yana da mahimmanci a tsaftace tsatsa, mai, ruwa, da datti akan sassan walda kafin walda.Gwada amfani da gajeriyar baka don walda.
