E70C-6M

Class: E70C-6M
AWS: A5.18

Conforms to Certification: AWS A5.18

Weld Process: Mig Welding Process

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 of 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.
