E70C-6M H4
AWS A5.18 E70C-6M H4
Description：
E70C-6M 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. Typical applications include machineries, shipbuilding, offshore structures, bridges and general fabrications, suitable for semi-automatic, automatic, single and multiple pass welding.
