Que hàn điện N46 – VD

Liên hệ

  • Welding low-carbon steel structures such as ship’s shell, basin, etc.
  • Welded joints without slag bearing and blow holes, having impact value and endurance bending strength
  • Weld metal revealing few impurities
  • High deposition coefficient

Applied standards

  • QCVN 21:2010/BGTVT MW2
  • ASME/AWS A5.1 E6013
  • EN ISO 2560-A-E 35 2 RA
  • JIS: D4303

Characteristics– applications: 

  • N46-VD is the electrode under the group of ilmenite sheath, so the welded joints don’t reveal blow holes or slag bearing. The well-fined welded joints are ductile, have endurance bending strength and high deposition coefficient.  Possibly welding at all positions.
  • Suitable for welding low-carbon steel under 430 ~ 490 Mpa load such as rolled-steel structures, ship’s shell, basin, etc.

Instruction for use:

  • Clean oil, grease and dust before welding
  • If the electrode is wet, dry it at 70 ~100 C for 30 ~60 minutes before welding
  • Process welding edges as regulated
  • Select appropriate current to avoid possible defects
  • Use AC or DC ± power
  • Size of the electrode and used current as follows:
