COREMAX 70C is a metal cored type flux cored wire of 490MPa high tensile steel. It shows us high-speed welding under large parameters, good crack-resistant and good porosity resistance to organic primer. Flat position and flat fillet welding position support only. Soft and stable arc, low spatter loss, very few slag removal to save time process. Higher deposition rate particularly. Typically used for shipbuilding’s automatic welding and general fabrications. It has a good resistance ability for porosity with galvanized plates.

Notes on Usage and Welding Condition:

• The oil stains and rust on the weldments should be cleared away.
• Designed for welding with 100% CO₂.
• When welding, the gas flow rate is generally 20 ~ 25L/min.
• Interpass temperature controlled to lower 150˚C for multi-pass welding.
• Use low input heat.
