Medium and High Tensile Steel

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.

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.
