Characteristics and Application

AWS A5.4 E316L-15 Welding rod, welding electrode The weld metal contains proper quantity of ferrite in austenitic structure. The welding can be done in all positions with good X-ray soundness and good mechanical properties. The product provides good notch toughness at the temperature as low as -196t The corrosion resistance against sulfuric acid, phosphorous acid is excellent. The electrode is designed for welding of LNG tank.

Notes on usage:

1. Clean up the contaminations on the base metal, groove and pass to pass with stainless steel brush.
2. Maintain short arc length. Moving range should be controlled within 2.5 times of the wire's dia when you are welding with weave method.

3. Dry the electrodes at 300—350℃ for 60 minutes before using. Take out consumables for half day consumption and keep in the environment at 100—150℃ during welding process.

4. Use lower current to prevent from crack and minimize base metal dilution.
