Welding Wire ER70S-6, ER50-6
ER70S-6 has good copper coating and resistance to corrosion. It is featured with stable wire feeding, smooth weld pass, small welding fume and spatter. Weld metal has good tensile strength and cracking-resistance at low temperature. It is suitable for all-position welding and wide current range. Suitable welding flux recommended: SJ101, SJ301, SJ501, HJ431, HJ350, etc.
Application:
Welding wire ER70S-6 (ER50-6) is applied to welding of high strength low alloy steel (Q390, Q420, Q460) in vehicles, hoist, mining machinery, construction machinery, structural steel, steel plate, steel pipes, pressure vessel, etc.
