Low-Alloy Steels Phau Ntawv Electrode E7018-C1L offshore FPSO soldering
Lub ntsiab muaj pes tsawg leeg yog 2.5% Ni steel, hlau hmoov tsis tshua muaj hydrogen potassium hom tes vuam pas nrig, ntawm -75C kev khiav hauj lwm kub
Qhov cuam tshuam toughness ntawm deposited hlau yog zoo heev; Ruaj khov arc, tsis tshua muaj txaws, zoo molding, yooj yim slag tshem tawm
X-Ray kev ua tau zoo heev
