Description and Applications |
|
H13 is a
retile type covered electrode for all position welding.
The bead appearance is good and penetration is shallow.
Arc is stable, very few spatters and slag is easy to
detach.
Welding of mild steel sheet for ships, rolling stock and
structures, and finish welding of heavy structure works. |

|
Guideline in Usage |
|
1. |
Electrode should be re-dried at 70
∼
120℃ for one hour. |
|
2. |
Pay
attention not to exceed the range of proper
current. |
|
3. |
If slag
detachability is not good due to welding base
metals with narrow groove, please use lime
Titania type electrodes, ex. HK32, H03 instead
of this electrode. |
