Mocheso o tlase oa tšepe ea ho tjheseletsa Electrode
W707
GB/T E5015-G
AWS A5.5 E7015-G
Tlhaloso: W707 ke eleketrode ea tšepe e nang le mocheso o tlase o nang le sodium e tlase ea hydrogen.Sebelisa DCEP (electrode e nepahetseng hona joale) 'me e ka chesetsoa maemong ohle.Tšepe e kentsoeng e ntse e na le matla a ts'usumetso e ntle ho -70°C.
Kopo: E sebelisetsoa ho tjheseletsa tšepe ea mocheso o tlase joalo ka 2.5Ni.
