Nickel ndi Nickel Alloy Welding Electrode
N307-1
GB/T ENi6062
AWS A5.11 ENCrFe-1
Kufotokozera: Ni307-1 ndi electrode yochokera ku nickel yokhala ndi zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (mwachindunji panopa electrode positive).Popeza weld ili ndi Nb, chitsulo choyikidwa chimakhala ndi pulasitiki wabwino komanso kukana ming'alu.
Ntchito: Ntchito kuwotcherera faifi tambala-chromium-chitsulo aloyi (monga UNS N06600, UNS N06601) ndi pamwamba zitsulo.Ali ndi zinthu zabwino zowotcherera zitsulo.Ikhoza kugwiritsidwanso ntchito pa kutentha kwa 980 ° C, koma pamene kutentha kuli pamwamba kuposa 820 ° C, kukana kwa okosijeni ndi mphamvu zidzachepa.
Chemical zikuchokera weld zitsulo (%):
C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Zina |
≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
Zimango za weld zitsulo:
Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % |
Zotsimikizika | ≥550 | ≥360 | ≥27 |
Zomwe tikulimbikitsidwa:
Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
Welding panopa (A) | 60-90 | 80-110 | 110 ~ 150 | 130-180 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 300 ℃ isanayambe ntchito yowotcherera;
2. M'pofunika kuyeretsa dzimbiri, mafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.Yesani kugwiritsa ntchito arc yayifupi kuti muwotchere.
