N-7018 and EASY 7018 NIHONWELD Low Hydrogen Welding Electrodes are premium-quality E7018 electrodes designed for welding carbon steel and low-alloy steel structures requiring high strength, excellent crack resistance, and superior weld quality. These iron-powder, low-hydrogen electrodes provide smooth arc performance, stable weld deposits, easy slag removal, and excellent mechanical properties, making them suitable for critical structural and fabrication applications. They can be used with AC or DC positive polarity (DCEP) and are recommended for all welding positions except vertical-down welding.
