Description and Applications |
|
HE8018-G is an iron powder low hydrogen type
electrode for all positions with excellent
mechanical properties and crack resistance.
Deposited metal contains approximately 1.5% Ni,
providing high notch toughness at low
temperature (-50℃).
It is suitable for welding of low temperature
service steels (ASTM A537 CLASS 2, A516).. |

|
Guideline in Usage |
|
1. |
Welding with excessively high
input should be avoided to assure strength and
toughness of weld. |
|
2. |
Base metal should be preheated.
Electrodes should be re-dried at 350∼400℃
for 60 minutes before use |
|
3. |
Keep the arc as short as possible |
