Description and Applications |
|
HE309Mo is a
lime-titanium type stainless steel electrode. It has
good weld ability and usability. The weld metal shows
excellent corrosion, acid, and heat resistance, and the
tensile strength is good in as-welded condition. It is
suitable for welding of 22% Cr—12%Mo stainless steel,
such as SUS316, SUS316L to mild steel. It is also
applicable to clad steel side welding carbon steel and
low alloy steel, etc. |

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 |
