- JIS: D5016
Characteristics – applications:
- E7018 – VD is the electrode under the group of low hydrogen sheath (iron powder supplemented). Weld metal has a low hydrogen content. Therefore, the welded joints are not cracked. They have high ductility and endure pressure at – 200 Welding slags are easily blistered and cleaned without slag bearing and splashing and explosion.
- Suitable for welding low-carbon steel under 490 ~550 Mpa load such as ship or boat’s structures, delivery pipe, drilling rig structures, etc.
- Metal is quickly condense, so it is easy to weld at all positions.

Instructions for use:
- Clean oil, grease and dust before welding
- Dry the electrode at 300 ~350 0 C for 30 ~60 minutes before welding
- Process welding edges as regulated
- Select appropriate welding current to avoid possible defects
- Lining weld beads should use a Ø3.2 electrode.
- Use AC or DC± power
