Ultratensal-Spl is a low hydrogen type electrode depositing a high strength and tough weld metal. The electrode possesses excellent operating characteristics low spatters, smooth and stable arc which is easy to strike and re-strike, easy deslagging and is suitable for welding in all positions. 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. Ensure cleanliness of the surface to be welded.
3. Use short arc and minimum heat input.
