JIS D5016
AWS E7018

Description and Applications
HE7018 is an iron powder low hydrogen type electrode with high efficiency welding. Re-striking and slag detachability are excellent. Reparative welding of cast iron and 500N/mm2 high tensile strength steels for ships and building.
 
Guideline in Usage
1.

Electrodes should be re-dried at 160 200℃ for one hour before use

2.

Keep the arc as short as possible
