Product Description

AWS E7018 welding electrode  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.

Applications:Suitable for welding important carbon steel and low-alloy steel structures such as ships,bridges,and offshore oil platforms, ocean  vessels, etc.
