LOW HYDROGEN ELECTRODE FOR WELDING STRUCTURAL STEELS SUBJECTED TO A SERVICE TEMPERATURE OF -500C
LN-80

CLASSIFICATION
- JIS Z 3241 DL5016-6A1 | AWS A5.5 E8016-G
PRODUCT DESCRIPTION
The design emphasis of the chemically basic flux is engineered to ensure the optimum weld metal properties demanded by the specification are fully met.
The basic flux containing the appropriate alloying elements with a controlled balanced addition of iron power, is extruded onto a high purity ferritic core wire with a blend of silicates that ensures both coating strength and a coating resistant to subsequent moisture absorption.
WELDING FEATURES OF THE ELECTRODE
Suitable for use both on AC or DC, the high arc drive combined with a fluid but quick freezing slag is ideal for site welding, particularly in the vertical up and overhead positions when no root gap exists and joint access is possible from both sides. The weld bead is convex and arc stability good. Metal recovery is some 95% with respect to core wire weight.
APPLICATIONS AND MATERIALS TO BE WELDED
For welding high tensile steels when good notch toughness is required. PRESSURE VESSEL STEELS
