Characteristics and Application

AWS A5.1 E7018-1 Welding rods, welding electrode is an iron powder type of low hydrogen electrode for all-position welding of 490N/mm2 grade high tensile steel. It performed with higher deposition rate, good soundness, good mechanical properties and smooth bead appearance. With excellent notch toughness at the temperature of -45℃, it is suitable for low alloy steels, medium carbon steels, heavy steel plates, cast steels and especially for welding of Aluminum Killed steel of LPG.

Notes on usage:

1. Dry the electrodes at 300-350℃ for 60 minutes and then keep at 100-150℃ before using
2. Use back-step method to prevent arc starting from blowholes and hold for 3-5 seconds at every end-UP.
3. Maintain short arc length. Moving range should be controlled within 3 times of the wire's dia when you are welding with weave method.

4. Clean up the contaminations on the base metal.
