N307-4                                                     

GB/T ENi6093

AWS A5.11 ENCrFe-4

Kufotokozera: Ni307-4 ndi electrode yochokera ku nickel yokhala ndi zokutira za hydrogen sodium.Gwiritsani ntchito DCEP (elekitirodi yamakonozabwino).Ili ndi ntchito yabwino kwambiri yowotcherera yokhala ndi kuyaka kokhazikika kwa arc, sipatter yochepa, kuchotsa mosavuta slag,

ndi weld wokongola.

Ntchito: Iwo ntchito kuwotcherera nickel-chromium-chitsulo aloyi, monga Ni600, Ni800/800H ndi ofanana kapena faifi tambala ofotokoza superalloys ndi kutentha ntchito 900 ° C. Angagwiritsidwenso ntchito kwa otsika-kutentha zitsulo munali Ni3% ~ 9%, monga ASTM A333, A334, A353, A522, The kuwotcherera A553 Angagwiritsidwenso ntchito dissimilar zitsulo kuwotcherera pakati Mo400, Ni825, zitsulo zosapanga dzimbiri ndi otsika aloyi chitsulo.

Chemical zikuchokera weld zitsulo (%):

Zimango za weld zitsulo:

Zomwe tikulimbikitsidwa:

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.
