Description and Applications |
|
H03 is a
lime Titania type covered electrodes. It posses a
smooth, quiet medium penetrating arc with minimal
spatter loss. Good slag removal with a finely rippled
bead contour. This quick freezing slag gives optimum
performance in vertical-down welding. Excellent for
welding complicated structure of thin and medium thick
plates. It is suitable for welding of medium or thin
plate for ships, vehicles, structures, and steel
constructions |

Guideline in Usage |
|
1. |
Dry
the electrodes at 70
∼
120℃ for an hour before use. |
|
2. |
Pay
attention not to exceed for the range of proper currents
and weaving motion. Welding with excessive current
lowers X-ray performance. The width of weaving motion
should be limited within 2.5 times electrode diameter
when it is necessary. |
