Nickel ndi Nickel AlloyKuwotchereraElectrode
N327-3
GB/T ENi6625
Kufotokozera: Ni327 -3 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, ndipo chimakhala ndi mphamvu zambiri komanso kukana kwa dzimbiri kwamphamvu kutentha kutentha komanso kutentha kwambiri.
Ntchito: Iwo ntchito kuwotcherera nickel-chromium-molybdenum aloyi, makamaka kuwotcherera ndi pamwamba pa UNS N06625 aloyi ndi mitundu ina zitsulo ndi faifi tambala-chromium-molybdenum aloyi gulu zitsulo, ndipo angagwiritsidwenso ntchito kuwotcherera Ni9% zitsulo pansi. kutentha kwapansi.
Chemical zikuchokera weld zitsulo (%):
C | Mn | Si | Cr | Ni | Mo |
≤0.10 | ≤2.0 | ≤0.8 | 20.0 ~ 23.0 | ≥55.0 | 8.0 ~ 10.0 |
Fe | Cu | Nb + Ta | S | P | Zina |
≤7.0 | ≤0.5 | 3.0 ~ 4.2 | ≤0.015 | ≤0.020 | ≤0.5 |
Zimango za weld zitsulo:
Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % |
Zotsimikizika | ≥760 | ≥420 | ≥27 |
Zomwe tikulimbikitsidwa:
Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 |
Kuwotchererapanopa (A) | 50-70 | 80-100 | 110 ~ 150 |
Zindikirani:
- Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 300 ℃ musanayambe kuwotcherera.Yesani kugwiritsa ntchito arc lalifupi kuti muwotchere;
- Ndikofunikira 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.
