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.
