Que hàn điện VD-6019

Liên hệ

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

Applied standards

  • QCVN 21:2010/BGTVT MW2
  • ASME/AWS A5.1 E6019
  • EN ISO 2560-A-E 35 2 RA
  • JIS: D4301

Characteristics – applications: 

  • VD – 6019 is the electrode under the group of ilmenite sheath, so the welded joints don’t reveal blow holes or slag bearing. Slags are easily blistered. 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 with high ductility and bending strength such as rolled-steel structures, ship’s shell, basin, etc.
