Tlhaloso: R306 ke electrode ea tšepe e hanelang mocheso ea perela e nang le sekoahelo sa potassium se nang le haeterojene e tlase se nang le 1% Cr - 0.5% Mo. AC le DC ka bobeli li ka sebelisoa, 'me li ka kopanngoa maemong 'ohle. Ho kopanngoa ho tlameha ho chesoa ho fihlela ho 160 ~ 250°C pele ho kopanngoa.
Tšebeliso: E sebelisoa bakeng sa ho tjheseletsa tšepe ea Cr 1% – Mo 0.5% e sa keneleng mocheso eo mocheso oa eona o sebetsang o leng ka tlase ho 520℃, joalo ka liphaephe tsa boiler, lijana tsa khatello, li-vaporizer le lisebelisoa tsa ho hloekisa peterole, jj.
Sebopeho sa lik'hemik'hale sa tšepe e welded (%):
