Characteristics and Application

AWS A5.1 E7018 Welding rods, welding electrode  is a low hydrogen type electrode for the welding of 490N/mm2 grade high tensile steel. The welding can be done with high deposition rate, good X-ray soundness and mechanical properties. It is especially suitable for nuclear power stations, petroleum chemical plants, and heavy steel plates. Proper base metals such as: structural steel, steel casting, thin plate, steel strip, carbon steel tube, etc..

Notes on usage:

1. Bake the electrodes at 300-350℃ for 60 minutes before using. Take out a batch of half day consumption and keep in the environment at 100—1500 during welding process.
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. Do not exceed the range of proper currents. Over heat input might decrease the impact toughness.
