AWS: SFA 5.5 E9015-B3Electrode zo mu byuma birwanya gukurura
Electrode nke ya hydrogen ifite 2.25Cr – 1Mo isuka icyuma, igaragaza imbaraga zidasanzwe za o n'ubudahangarwa ku bushyuhe buri hejuru kugeza kuri 575 Cr. Ikoreshwa mu gusudira icyuma kidahangarwa na 21⁄4 Cr-1 Mo kidahangarwa na creep na Cr-Mo-V kidahangarwa na hydrogen munsi y'umuvuduko ndetse no ku byuma bisa n'icyuma gisukwa. Ikoreshwa risanzwe ririmo kubaka boiler y'umwuka, gusudira imiyoboro y'umwuka n'ishyushya cyane, inganda z'amashanyarazi, uruganda rutunganya peteroli n'inganda za shimi.

Kwitonda
1. Ongera wumishe electrodes kuri 250-300 C mu gihe cy'isaha imwe, nk'uko bisanzwe tubisabwa.
2. Koresha umugozi mugufi n'agasaro k'imigozi.
