Nickel ndi Nickel Alloy Welding Electrode
Ni202
GB/T ENi4060
AWS A5.11 ENiCu-7
Kufotokozera: Ni202 ndi Ni70Cu30 Monel alloy electrode yokhala ndi titaniyamu calcium coating.Itha kugwiritsidwa ntchito pa AC ndi DC.Chitsulo choyikidwa chimakhala ndi mphamvu yabwino yolimbana ndi ming'alu chifukwa cha manganese ndi niobium yoyenera.Ili ndi ntchito yabwino kwambiri yowotcherera yokhala ndi kuyaka kwa arc kokhazikika, sipatter yochepa, kuchotsa slag kosavuta, ndi weld wokongola.
Ntchito: Amagwiritsidwa ntchito pakuwotcherera aloyi ya nickel-copper and dissimilar steel, ndipo angagwiritsidwenso ntchito ngati zinthu zokutira zosinthika.
Chemical zikuchokera weld zitsulo (%):
| 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 |
Zimango za weld zitsulo:
| Yesani chinthu | Kulimba kwamakokedwe Mpa | Zokolola mphamvu Mpa | Elongation % |
| Zotsimikizika | ≥480 | ≥200 | ≥27 |
Zomwe tikulimbikitsidwa:
| Ndodo diameter (mm) | 2.5 | 3.2 | 4.0 |
| Welding panopa (A) | 50-80 | 90-110 | 110 ~ 150 |
Zindikirani:
1. Elekitirodi iyenera kuphikidwa kwa ola limodzi mozungulira 250 ℃ isanayambe ntchito yowotcherera;
2. M'pofunika kuyeretsa dzimbiri, mafuta, madzi, ndi zonyansa pazigawo zowotcherera musanayambe kuwotcherera.
