Tlhaloso: R306 ke electrode ea tšepe e sa keneleng mocheso ea pearlitic e nang le mocheso o tlaase oa hydrogen potassium o nang le 1% Cr - 0.5% Mo. Ka bobeli AC le DC li ka sebelisoa, 'me li ka chesetsoa libakeng tsohle.Weldment e tlameha ho futhumatsoa pele ho 160 ~ 250 ° C pele ho tjheseletsa.
Kopo: E sebelisetsoa ho cheseletsa Cr 1% - Mo 0.5% tšepe e sa keneleng mocheso eo mocheso oa eona o sebetsang o ka tlase ho 520 ℃, joalo ka liphaephe tsa boiler, likepe tsa khatello, li-vaporizer le lisebelisoa tsa ho hloekisa peterole, joalo-joalo.
Sebopeho sa lik'hemik'hale tsa tšepe ea weld(%):
