Na'urar Walda ta Nickel da Nickel Alloy
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Bayani: Ni202 wani lantarki ne mai suna Ni70Cu30 Monel wanda ke da sinadarin calcium na titanium. Ana iya amfani da shi don AC da DC. Karfe da aka ajiye yana da juriya mai kyau saboda yawan sinadarin manganese da niobium. Yana da kyakkyawan aikin walda tare da ƙonewa mai ƙarfi, ƙarancin fesawa, sauƙin cire slag, da kyakkyawan walda.
Amfani: Ana amfani da shi don walda ƙarfe mai kama da nickel da jan ƙarfe, kuma ana iya amfani da shi azaman kayan rufewa na wucin gadi.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Mn | Fe | Si | Nb | Al | Ti | Cu | Ni | S | P |
| ≤0.15 | ≤4.0 | ≤2.5 | ≤1.5 | ≤2.5 | ≤1.0 | ≤1.0 | 27.0 ~ 34.0 | ≥62.0 | ≤0.015 | ≤0.020 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarfin bayarwa Mpa | Ƙarawa % |
| An Garanti | ≥480 | ≥200 | ≥27 |
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 2.5 | 3.2 | 4.0 |
| Walda na yanzu (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Sanarwa:
1. Dole ne a gasa wutar lantarki na tsawon awa 1 a kusan 250℃ kafin a fara aikin walda;
2. Yana da mahimmanci a tsaftace tsatsa, mai, ruwa, da ƙazanta a kan sassan walda kafin a yi walda.
