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. |
