Characteristics and Application

AWS A5.5 E8018-G Welding rods, welding electrode  is an electrode for the welding of 550N/mm2 grade low-temperature service steel. It provides good notch toughness at -45℃ due to its containing of 0.8%Ni. It is suitable for the welding of Aluminum Killed Steel used at LPG tanks. Proper base metals are also including high-carbon steel, low Manganese alloy steel, cast iron, steel pipe for low temperature service, pressure vessel, etc..

Notes on usage:

1. Dry the electrodes at 350-400℃ for 60 minutes before using.
2. Do not exceed the range of recommended current. Over heat input might decrease the impact value.
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. Thick plate should be preheated at 50—100℃.
