Description :
- N-7018 is an iron powder low hydrogen type electrode containing large amounts of iron powder in coating flux to give higher deposition rates
- Deposited metal demonstrates excellent mechanical properties, crack resistance, and X-ray quality
- Good weldability, such as smooth and stable arc, easy slag removal, low spatters, and nice bead appearance

The information contained or otherwise referenced herein is presented only as “typical” without guarantee or warranty, and Industrial Welding Corporation expressly disclaims any liability incurred from any reliance thereon. Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
Welding of 50 kgf/mm2 high tensile strength steels for ships, steel frames, bridges, and pressure vessels
General civl construction works
Require a drag to 1/16 inches maximum arc length to obtain the desired mechanical properties and weld quality
An arc length of 1/8 inch or longer may result in porosity and serious deterioration of impact properties
Take the backstep method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting
Polarity: Use DC (+) whenever possible with 4.0mm and smaller sizes
