Basic coated low Hydrogen type High Tensile Electrode for low temperature service.
CLASSIFICATION : AWS/SFA-5.5: E 8018-G
IS-1395: E 55BG 129Fe
CHARACTERISTICS : A basic coated, hydrogen controlled, iron powder electrode depositing 0.65% Ni weld metal with exotic finish and radiographic joints, gives low spatter, smooth arc, also works well to resist atmospheric corrosion.
APPLICATION :
1) Suitable for welding on Quenched & Tempered steels.
2) Pressure vessels, storage tanks, penstocks, fine grained steels.
3) Industrial equipment subjected to sub-zero temperature.
4) Other steel categorized for high strength.
RE-DRY CONDITION : Re-Dry the electrode at 300°C for 1 hrs, before use.
