Tlhaloso: R406 ke electrode ea tšepe e sa keneleng mocheso ea pearlitic e nang le pente ea potasiamo ea haedrojene e tlaase e nang le 2.5% Cr - 1% Mo.Both AC le DC e ka sebelisoa, 'me e ka chesetsoa libakeng tsohle.The weldment e tlameha ho futhumatsoa pele ho 160 ~ 200 ° C pele ho tjheseletsa.
Kopo: E sebelisetsoa ho cheselletsa meaho ea tšepe e sa keneleng mocheso ea Cr2.5Mo pearlitic, joalo ka liphaephe tse nang le mocheso o phahameng le likhatello tse phahameng tse nang le mocheso o sebetsang o ka tlase ho 550 ° C, metjhini ea lik'hemik'hale ea maiketsetso, le lisebelisoa tsa peterole e pshatlang.
