China Alkaline Slag Low Hydrogen Potassium Coating Welding Tools

ABS E7018 Low Hydrogen Welding Electrodes
TOKOAWS A5.1 E7018 is an outstanding quality all position welding electrode covered with extra low hydrogen potassium type coating for high tensile strength mild steels and low alloy steels. Its nominal welding efficiency is about 110% due to iron powder is contained. The weld metal shows an exellent low temperature toughness and high crack-resistance.It is widely used in important projects of ship, boilers, high pressure vessels, bridges, skyscrapers, offshore drilling Industrial Equipment & Components platforms, nuclear power plants and so on. The groove of base metal should be cleared impurities away and the electrode must be baked at 400oC then be held 1-2 hours before welding, 2.5mm or less one should be done by 350oC then be held 1 one hour.
