Applied standards
- TCVN 3223:2000 E513
- ASME/AWS A5.1 E7015
- JIS: D5016
Characteristics – applications:
- 6B – VDis the electrode under low-hydrogen group. Weld metal has a low hydrogen content, thereby limiting cracks. The welded points are ductile. Welding slags are easily blistered and cleaned without splashing and explosion.
- Suitable for welding low-carbon and low-alloy steel under 490~550 Mpa load such as building structures, mining gallery, kicker, ferry dock, etc.
