Product Description
Product Name: ER70S-6 Carbon Steel MIG Welding Wire
AWS Classification: ER70S-6
Type: Copper-coated solid wire
Shielding Gas: CO₂ or Ar+CO₂ mixed gas
Standard Compliance: AWS A5.18 / ASME SFA-5.18 / ISO 14341-A G3Si1
ER70S-6 is a premium copper-coated solid welding wire designed for MIG/MAG welding of mild and carbon steels. With higher deoxidizer content (manganese and silicon), it provides superior arc stability and weld bead appearance, especially when welding over mill scale or slightly rusted surfaces.
It is widely used in general fabrication, machinery manufacturing, automotive parts, pressure vessels, pipelines, and structural steel work, offering high deposition efficiency, low spatter, and excellent mechanical properties.
Key Features
-
Excellent weldability and stable arc performance
-
High deposition rate and smooth bead appearance
-
Low spatter, minimal slag
-
Strong resistance to porosity even on rusted or scaled steel
-
Suitable for single and multi-pass welding in all positions
-
Works with 100% CO₂ or Argon + CO₂ shielding gases
Typical Applications
-
General fabrication and manufacturing
-
Automotive components and frames
-
Shipbuilding and heavy machinery
-
Pressure vessels and boilers
-
Construction steel structures
-
Pipelines and storage tanks
