Description and Applications |
|
H5E7024 is a titania iron type covered electrodes. As it has excellent bead appearance and also good re-striking property and detachability, it is suitable for horizontal or flat fillet welding of mild and 50 kgf/m㎡ high tensile steels for bridge or building constructions. Guideline in Usage. |

Guideline in Usage |
|
1. |
Dry the electrodes at 100~150℃ for 60 minutes before use. |
|
2. |
High efficient fillet welding can be done by gravity welding process. |
