Description and Applications |
|
As its weld metal has low carbon austenitic structure
which contains suitable ferrite, crack resistance is
good. It provides good corrosion resistance and good
heat resistance in as-welded condition.
Welding of dissimilar metals such as stainless steel to
carbon steel or low alloy steel |

Guideline in Usage |
|
1. |
Preheat is
unnecessary. |
|
2. |
Keep the short
arc and low amperage. Weaving width should be
within 2.5 times electrode diameter. |
|
3. |
Electrodes should be re-dried at
250
～
300℃ for one hour before use |
|
4. |
Remove dirt such
as oil and dust from the groove |
