An iron powder, low hydrogen type electrode producing a tough and ductile weld metal for welding heavy and rigid structures subjected to dynamic loading and impact. The weld metal is of radiographic quality and displays remarkable impact strength even at minus 50°C. Typical applications include welding of carbon steels, steels sensitive to hydrogen embrittlement, heavy and rigid structures, pressure vessels and equipment subjected to severe stress and requiring good toughness properties at sub-zero temperatures down to minus 50°C.
1. Re-dry the electrodes at 250-300 C for one hour, as per our standard recommended practice.
2. Use short arc and stringer bead.
