Product Description

E7018 welding electrode/ rod Application:  

E7018 welding electrode/ rod  is widely in important projects of ships, boilers, high press vessel, bridges, skyscrapers, offshore drilling platforms, nuclear power stations etc. The groove of base metal should be cleared away impurities and the electrode must be baked at a temperature to 400 degree then be held 1-2 hours before welding, 2.5mm one should be done by 350 degree then be held 1 hour.
