An all positional, medium heavy coated, iron powder type, low hydrogen electrode depositing radiographic quality welds which are highly resistant to hydrogen induced cracking.
Weld beads are smooth and spatter level is low. Works well on AC & DC.
Used for welding C - 0.5% Molybdenum low alloy steels, high tensile steels, used in high temperature applications. Finds application in the fabrication of high pressure boilers, turbine equipments, high pressure piping, pressure vessels, heavy welded fabrication, oil refining equipments, etc.,
It is recommended to dry the electrodes at 250° C for 1-2 hours. Maintain short arc. Preheating (150°C-200°C) is recommended on thicker sections.
