Characteristics and Application

AWS A5.1 E7018-1 H4R Welding rods, welding electrode is an iron powder low hydrogen type electrode for all-positioned welding of 490N/mm2 grade high tensile steel. The welding provides high deposition rate, good soundness, good mechanical properties, excellent moisture absorbency resistance and smooth bead appearance. Because of excellent notch toughness at the temperature of -45℃, it is very suitable for low alloy structure, medium carbon steels, barge offshore rigs and shipbuilding

Notes on usage:

1. Take the backstep method to prevent blowholes at the arc starting.
2.Keep the arc as short as possible.
3.Be sure to clean up the base metal surface from all contamination. 4.1f electrode has been exposed to the atmosphere over 8 hours, it must be rebaked at 400℃ for one hour.
