AWS A 5.5: E 7018 - A1 |
Description |
A heavy coated basic iron powder type low hydrogen electrode for welding of carbon- molybdenum creep resistant steels of 0.5Mo for creep resistance upto 530 0 C. The electrode is having very good operating characteristics like smooth and steady arc, slag detachability. The electrode can be used easily in positions. Weld deposit is of high radiographic soundness. |
Application |
Welding of plates, sheets, pipes, and tubes of low alloy creep resistance steel such as 17Mn, 19Mn, 15Mo and equivalent grades used in boilers, power plant, oil refineries etc. |
