E7018 Welding Electrode
The E7018 welding electrode comes with low hydrogen potassium coating. This welding accessory offers excellent wedalbility in all position welding for high strength steel and low alloy steel. Thanks to iron powder contained, our low alloy welding rod offers 11% welding efficiency.
Our welding electrode is characterized by remarkable impact toughness at low temperature and outstanding crack resistance. This high strength steel electrode excels at catering to demanding welds for ships, boilers, high-pressure vessels, bridges, high-rise buildings, offshore platforms and nuclear power plants, etc.
