2. Feature:

E7015 welding electrode 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 low temperature impact roughness. 

It's widely used for welding key 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.
