GB：E5015
AWS：E7015
Application：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, etc., and also used for welding on thick plates and hard-to-weld carbon steel structures.：

E7015

According with GB E5015
Corresponding with AWS E7015

Introduction: E7015 is a kind of carbon steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. It has excellent welding performance, stable arc, fewer spatters and good slag detachability. The deposited metal has excellent mechanical properties, crack-resistance and good low temperature impact roughness.

Applications: 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, etc., and also used for welding on thick plates and hard-to-weld carbon steel structures.

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 weld, such as rust, oil stains, moisture, etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is suitable.

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.
