Medium and High Tensile Steel

ULTRATHERME

AWS: SFA 5.5 E11018-G

Ultratherme is a low hydrogen type electrode ideally suited for welding high strength steels, fine-grained steels, HSLA, Q&T steels, etc. The weld metal possesses high strength combined with good toughness properties. Ideal for welding high strength steels used in earth moving industry, etc.

Precaution

1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300°C for one hour.

2. Use short arc and minimise heat input during welding.
