JIS D5016
AWS E7016

Description and Applications

HE7016 is a low hydrogen type electrode for all position welding, especially in overhead welding. The weld metal shows excellent mechanical property, crack resistance, and X-ray quality.

For the welding of 500 N/mm2 high tensile strength steel for ships, buildings, bridges, and vessels.

 

Guideline in Usage

1.

Electrodes should be re-dried at 300350 ℃ for one hour before use.

2.

Back step method should be used to prevent blowholes and pits at the arc starting. Keep the arc as short as possible.

3.

Remove all dirt such as oil and dust from the groove.
