Description:

E7018-1 is a kind of carbon steel electrode with iron powder low-hydrogen potassium type coating. AC/DC. All-position welding. Because more alloying elements have been added, it has excellent plasticity and low temperature impact toughness. It has excellent welding performance, stable arc, fewer spatters, good slag detachability and higher deposition efficiency

Application:
Suitable for welding carbon steel and low-alloy steel structures like offshore oil platforms, ocean going vessels, etc
