Description and Applications |
|
As its weld metal has low
carbon austenitic structure, which contains suitable
ferrite, crack resistance is good. The deposited metal
has gold color and the bead is beautiful. Weld ability
is excellent, i.e. slag is easy to detach, arc is stable
and spatters are less. |

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. |
