Nickel ndi Nickel Alloy Welding Electrode

N307-2                                                     

GB/T ENi6133

AWS A5.11ENiCrFe-2

Kufotokozera: Ni307-2 ndi electrode yochokera ku nickel yokhala ndi zokutira zotsika za haidrojeni.Gwiritsani ntchito DCEP (mwachindunji panopa electrode positive).Popeza chowotcherera chimakhala ndi kuchuluka kwa molybdenum, niobium ndi zinthu zina zophatikizira, chitsulo choyikidwa chimakhala ndi kukana kwabwino kwa ming'alu.

Ntchito: Ntchito kuwotcherera faifi tambala-chromium-iron aloyi (monga UNS N08800, UNS N06600), makamaka oyenera kuwotcherera zitsulo zosiyana, kusintha wosanjikiza kuwotcherera ndi pamwamba kuwotcherera, ndipo angagwiritsidwenso ntchito pamene kutentha ntchito ndi 980 ° C, koma imatha kukana makutidwe ndi okosijeni kutentha kukakhala kopitilira 820 ° C Kuchepetsa kugonana komanso kulimba.

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.
