Features and applications:

N42 - VD is a rutile-coated welding electrode. It produces welds with few defects, a stable arc, minimal spatter, and easily removable slag. The weld is well-refined, resulting in high ductility and good resistance to bending fatigue. It can be welded in all positions.
Suitable for welding low-carbon steel with compressive strength from 430 to 490 MPa, such as: rolled steel structures, barge hulls, ferries, storage tanks, etc.

Instructions for use:

Clean off oil, grease, and dirt before welding.
If the welding rods are damp, dry them at 70-100 ^° C for 30-60 minutes before welding.
The weld edges are processed according to specifications.
Choose the appropriate welding current to avoid defects.
Use AC or DC power supply.
