Dur aloi isel Gwneuthuriadau uniadu metel ER80S-Ni3 wedi'u gorchuddio â nwy
Gwifren weldio wedi'i gorchuddio â nwy ar gyfer dur tymheredd isel gradd 550MPa.
Mae gan y metel tawdd briodweddau mecanyddol da a chaledwch effaith dda ar -75 ℃.
Bwydo gwifren llyfn, arc sefydlog, ffurfio hardd, llif da o haearn tawdd, llai o sblash, gyda pherfformiad proses weldio rhagorol.
