AWS ER70S-G

Description and Applications
HR70S-G is a gas metal arc welding wire with CO2 shielding. Arc is stable, spatters are few, and weld ability is excellent, even in high welding current range. High efficiency is obtained since deposition rate is high and penetration is deep.
Butt or fillet MAG welding of mild steel an 500N/mm2 high tensile strength steel such as ships, vehicles, buildings, bridges, and industrial machinery.
 

Guideline in Usage

1. Suitable for flat, horizontal, angle welding at a high current range.
2. Automatic flat and vertical downward is possible.
3. Use CO2 gas for shielding in welding.
