ULTRATENSAL electrode is low hydrogen, iron powder type electrode for welding high strength steels. The weld deposits of this electrode have high strength with excellent toughness. It is ideally suited for welding high tensile steels, grain refined Q&T steels such as USS-T1, SA 517 grades and their equivalents, Fabrication of penstocks, heavy structures, earth moving equipments, etc.
1. Re-dry the electrodes at 300-350°C for one hour.
2. Use low current, short arc and stringer beads.
