Class: E70C-6M

AWS: A5.18

 

TYPICAL APPLICATION:

E70C-6M is designed for welding of 490MPa high tensile steel with only Ar/CO₂ gas mixtures.  It is especially suitable for welding and has a high tolerance to primer.  Typical applications include machineries, shipbuilding, offshore structures, bridges and general fabrications.

 

CHARACTERISTICS ON USAGE:

• Wire is a metal type of flux cored wire for flat and horizontal position welding
• Slag quality is almost the same as solid wire and multiple pass welding can be performed without removing slag.
• 20% higher productivity can be achieved when compared to solid wires and it features good penetration, high resistance to porosity, good wetting behavior as well as low hydrogen contents.
• E70C-6M is intended for semi-automatic, automatic, single and multiple pass welding.
