Medium and High Tensile Steel

ULTRATHERME-H

AWS: SFA 5.5 E10016-G

Basic coated, extra low hydrogen electrode ideally suited for welding high strength steels, Q&T steels. The weld metal is of radiographic quality and possesses excellent strength combined with good toughness. Ideal for welding high strength steels under the site conditions having high relative humidity and higher joint restraints, as the extra low hydrogen levels ensure freedom from hydrogen induced cracking.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrode at 400°C for one hour.

2. Keep the minimum heat input during welding.

3. Controlling preheat and inter pass temperatures between 120-150°C.

4. Use stringer beads and minimize weaving.
