LT·J507 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes
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.
Conform to Standard

AWS A5.1 E7015
ISO 2560-B-E 49 15 A
Purpose:AWS A5.1 E7015 is applied in welding medium-carbon steel and low-alloy structures such as 16Mn, 09Mn2Si, 09Mn2V and the steels used in shipbuilding such as A, B, D, E. It is also used in thick steel plates and the carbon steel structures that are difficult to weld.

Notes:
1. The electrode must be preheated at the temperature of 350°C for 1 hour. Preheat the rod whenever it is used.
2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.
3.Short arc is required to perform welding. Narrow weld path is preferred.
