Nickel ndi Nickel Alloy Welding Electrode
N327-6
GB/T ENi6620
AWS A5.11 ENCrMo-6
Kufotokozera: Ni327 -6 ndi electrode yochokera ku nickel yokhala ndi zokutira zotsika za hydrogen sodium.Gwiritsani ntchito DCEP (elekitirodi yamakonozabwino).Chitsulo choyikidwa chimakhala ndi pulasitiki yabwino kwambiri, kulimba komanso kukana ming'alu.Chitsulo choyikidwa chimakhala ndi mzere wokulirapo wofanana ndi chitsulo, ndipo chimakhala ndi mphamvu zambiri komanso kukana kwa dzimbiri pa kutentha ndi kutentha kwambiri.
Ntchito: Amagwiritsidwa ntchito powotcherera zitsulo za Ni9%, ndipo amathanso kugwiritsidwa ntchito powotcherera zitsulo zosiyanasiyana komanso ma aloyi ovuta kuwotcherera.
Chemical zikuchokera weld zitsulo (%):
| C | Mn | Si | Ni | Mo | Fe | Cu |
| ≤0.10 | 2.0 ~ 4.0 | ≤1.0 | ≥55.0 | 5.0 ~ 9.0 | ≤10.0 | ≤0.5 |
| Nb + Ta | W | Cr | S | P | Zina |
|
| 0.5 ~ 2.0 | 1.0 ~ 2.0 | 12.0 ~ 17.0 | ≤0.015 | ≤0.020 | ≤0.5 |
|
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % |
| Zotsimikizika | ≥620 | ≥350 | ≥32 |
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 |
| Welding panopa (A) | 50-70 | 80-100 | 110 ~ 150 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 300 ℃ musanayambe kuwotcherera.Yesani kugwiritsa ntchito arc lalifupi kuti muwotchere;
2. M'pofunika kuyeretsa dzimbiri, mafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.
3. Yesani kugwiritsa ntchito mphamvu ya mzere waung'ono powotcherera, ma multilayer ndi ma pass-pass kuwotcherera.
