Features and applications:

N55.6B - VD is a low-hydrogen welding rod. Its low hydrogen content in the metal limits cracking, resulting in welds with high ductility. The slag is easily removed, easy to clean, and has minimal spatter.
Suitable for welding low-carbon and low-alloy steels with load capacities from 490~550 Mpa, such as: construction structures, mines, foundations, bridges, ferries, etc.

Instructions for use:

Clean off oil, grease, and dirt before welding.
Preheat welding rods to 300-350 ^° C for 30-60 minutes before welding.
The weld edges are processed according to specifications.
Choose the appropriate welding current to avoid defects.
Use a positive DC power source for welding (DC +).
