AWS E7015
Welding Electrode / Welding Rod / Welding Wire
Introduction:
The E7015 basic carbon steel electrode is coated with low-hydrogen natrium and is suitable for DCRP (Direct Current Reversed Polarity) welding. The welding wires are stable and provide excellent welds with few spatters and good slag detachability. Welds made with our welding rods are crack resistant and have excellent low temperature impact toughness.
Applications:
These electrodes are often used for welding medium-carbon steel and low-alloy steel structures (under pressure and moving loads), such as 16Mn, 09Mn2Si, 09Mn2V and A, B, D and E steel for ships. They can also be used for welding thick plates and hard-to-weld carbon steel structures.

Packing Details:
In carton of 20kgs/net, consisting of 8 boxes x 2.5kgs for 2.5mm, & 4 boxes x 5kgs for other sizes.
With/ without pallets (fumigation-free pallets) upon customer’s request.
Instructions:
1. The electrodes must be baked under 300~350℃ for an hour before welding and applied as soon as baking is completed.
2. The stains on the welding surface, such as rust, oil stains, moisture, etc., must be cleared away before welding.
3. When welding, a short arc must be used and a stringer bead is suitable.
