mt-12 welding electrode introduction
E7018 is a kind of carbon steel electrode with iron powder low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. The deposition efficiency is higher due to the iron powder in the coating. It has stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. The deposited metal has excellent mechanical properties.
Usage:
Used for welding carbon and low-alloy steel structures, such as 16Mn, etc.

Instructions:
1.The electrodes must be baked under 300~350℃ for an hour before welding and used as soon as baking is completed.
2.The stains on the work pieces, such as oil stains, rust, moisture, etc., must be cleared away before welding.
3.When welding, operation with short arc and stringer bead is suitable.
