Nikel ndi Nickel Alloy Welding Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Kufotokozera: Ni202 ndi electrode ya Ni70Cu30 Monel alloy yokhala ndi titanium calcium coating. Itha kugwiritsidwa ntchito pa AC ndi DC. Chitsulo chomwe chayikidwa chili ndi kukana bwino ming'alu chifukwa cha kuchuluka kwa manganese ndi niobium koyenera. Ili ndi magwiridwe antchito abwino kwambiri olumikizirana ndi kutentha kokhazikika kwa arc, kutayikira kochepa, kuchotsedwa mosavuta kwa slag, komanso weld yokongola.
Kugwiritsa Ntchito: Imagwiritsidwa ntchito polumikiza aloyi wa nickel-copper ndi chitsulo chosiyana, ndipo ingagwiritsidwenso ntchito ngati zinthu zosinthira.
Kapangidwe ka mankhwala a chitsulo chosungunula (%):
| 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 |
Kapangidwe ka makina a chitsulo chosungunula:
| Chinthu choyesera | Kulimba kwamakokedwe Mpa | Mphamvu yobereka Mpa | Kutalikitsa % |
| Chotsimikizika | ≥480 | ≥200 | ≥27 |
Mphamvu yovomerezeka:
| M'mimba mwake wa ndodo (mm) | 2.5 | 3.2 | 4.0 |
| kuwotcherera panopa (A) | 50 ~ 80 | 90 ~ 110 | 110 ~ 150 |
Zindikirani:
1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha pafupifupi 250℃ isanayambe kuwotcherera;
2. Ndikofunikira kuyeretsa dzimbiri, mafuta, madzi, ndi zinyalala pa zipangizo zolumikizira musanagwiritse ntchito.
