ER70S-G High Strength Welding Wire
The ER70S-G high strength welding wire is a kind of copper coated welding wire for low alloy steel. This gas shielded welding wire enjoys the company of CO2 or Argon-rich gas. Thanks to addition of Ti element, more refined deposition metal is achieved with outstanding mechanical properties.
This high strength welding wire is the industry-proven solution to applications requiring large current and high efficiency. Our filler material is designed for high-strength low-alloy steel (e.g. X65, 16Mn and 18Nb) applied to boiler, pressure vessel, bridge, hoisting machine, transport machine, engineering machinery, shipbuilding, pipeline and container, etc.
