Elepipe®8018-G

General description

Basic covered low hydrogen electrode primarily designed for hot, fill and cap pass vertical down pipe welding

Recommended for pipe grades up to and including API 5L X70

Low temperature impact properties down to -46°C

Unique “hot start” tip helps initiate the arc and quickly establish puddle control

Slag design allows for easy control of weld puddle
