JIS D5018
AWS E7018

Description and Applications

HD5018 is an iron powder low hydrogen type electrode contains a large amount of iron powder in coating flux. Weld metal shows excellent mechanical properties, crack resistance, and X-ray quality. Weld ability is good and high welding efficiency can be obtained.

Welding of 500N/mm2 high tensile strength steels for ships, steel constructions, bridges and pressure vessels.

Guideline in Usage

Electrodes should be re-dried at 300 350 for one hour before use


Back step method should be applies to prevent blowholes and pits at the arc starting and arc length should be kept as short as possible during welding
