Basic coated, Hydrogen controlled iron powder type Electrode for high tensile steels.
CLASSIFICATION : AWS/SFA-5.5: E 9018M
IS-1395: E 63 BM 129Fe
IS-1395: E 63 BM 129Fe
CHARACTERISTICS :
A hydrogen controlled, iron powder electrode for welding high tensile structural steels. It gives smooth arc, low spatter, easy slag detachability, medium penetration and welded joints are of radiographic quality and weld metal exhibits high impact values at sub-zero temperatures.
APPLICATION :
- pressure vessels.
- chemical plants and machinery parts.
- Equipment such as penstocks to be subjected to -50°C.
- Heavy earthmoving machinery, fabrication.
- Automobile parts.
RE-DRY CONDITION : Re-Dry the electrode at 250°C for 1 hrs before use.
