Added with an appropriate amount of such alloying element as Cu, Cr, Ni and Mo, the ER 44-8 weather resistant low alloy steel argon- rich shielded welding wire provides the welding seam with excellent atmospheric corrosion resistance and welding technological property with good shaping, mirror spattering stable electric arc and all-position welding advantages, which enormously increase product service life and can meet a variety of specific weather conditions.
The Ar+CO2 gas shielded welding is widely used for the welding of weather resistant low alloy steel, such as 09CuPTiRE, 16CuPCrNi,15MnCuCrQT for containers, rolling stock, drilling platforms, bridges and steel frames, which conforms to TB/T2374ER44-8(H08MnSiCuCrNiLi)
