A Hydrogen controlled basic coated Electrode For welding high and medium tensile steels.
CLASSIFICATION :AWS/SFA-5.1: E 7024, BS 639 E 5122RR14032 IS-814: ERR 5242 KX , DIN 1913 E 5122RR1135140
CHARACTERISTICS :
An extra heavy coated, iron powder, rutile type electrodes for achieving high deposition efficiency 140% Min. Electrode is touch welding type, gives smooth arc, least spatter losses, reduces welding time and gives increased productivity and output by using high current. Welds are of radiographic quality.
APPLICATION :
- Heavy sections machinery components.
- Heavy Structural’s works like cranes and bridges.
- Assembly of earthmoving equipments.
- Welding heavy columns, locomotive.
- Heavy machinery parts, in shipbuilding , pressure vessels etc.
RE-DRY CONDITION : Re-Dry the electrode at 120°C for one hour, for best results.
