Description and Applications |
HE308H is the same as
HE308 electrode except that the allowable carbon content
higher than HE308L. It is a lime-Titania type electrode
with 19%Cr- 9%Ni deposited metal. Slag is easy to remove
and arc is stable, spatters are less and bead appearance
is beautiful.
HE308H is suitable for
welding of SUS308H base metal. |

Guideline in Usage
|
1. |
Electrodes should be re-dried at
250
∼
300℃ for one hour before use |
2. |
Excessively wide weaving may cause welding
defects. Keep weaving width to less than 2.5
times electrode diameter. |
