Welding Wire ER70S-3, ER50-3
ER70S-3 (ER50-3) is gas shielded welding wire for mild steel. Protection gas could be CO2 or argon-rich mixture. It is suitable for single-pass and multi-pass welding. Welding performance is featured with small spatter, smooth weld pass, high resistance to cracking, especially suitable for high speed welding of thin plate under low heat input.
Application:
Suitable for mild steel (Q195, Q215) and low alloy steel (12Mn) in bridge building, vehicles, pipes industry.
