JIS D309-16
AWS E309-16

Description and Applications

HE309 is a lime-Titania type electrode. Weld ability is excellent. Spatters are less and crack resistance is good.

Welding of dissimilar metals such as stainless steel 309S, 304 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
