Product Description

carbon steel E7018
Detailed description:
E7018
AWS A5.1 E7018
Explain:
E7018 is a carbon steel welding rod with iron powder and low potassium hydrogen content. It is used for AC and DC purposes. Because the coating contains iron powder, the deposition efficiency can be improved. The arc is stable, less spatter, easy to remove slag, good technological performance, good mechanical properties of deposited metal, and can be welded in all position.
purpose:
For welding of carbon steel and low-alloy steel structure, such as 16Mn, etc..

Matters needing attention:
The electrode must be baked at 350 ºC 1H before welding.
The rust, oil, moisture and other impurities of the weldment must be removed before welding.
Welding shall be done in short arc, with narrow bead.1
