Applied standards
- ASME/AWS A5.17 EH 11K
Characteristics – applications:
- EH 11 K – VD is the submerged arc welding wire. Copper plating or no copper plating. Used for semi-automatic or automatic welding machines. The welded joints are intensively penetrated and smooth.
- Suitable for welding low-carbon steel under the load up to 550 Mpa such as the manufacture of beam frame, arm crane, etc. Appropriate for welding straight lines, circles, etc.
- Suitable for welding with VD-431or equivalent
- Welding capacity higher than other methods of welding
