Carbon Steel Welding Electrode
J507
GB/T E5015
AWS A5.1 E7015
Description: J507 is a carbon steel electrode with low hydrogen sodium coating. Deposited metal has good plasticity, toughness, and crack resistance. Use DCEP (direct current electrode positive), and can weld in all positions.
Application: Used for welding of medium carbon steel and some low alloy steel structures, such as 09Mn2Si, Q345, 09Mn2V, etc.

Notice:
1. The electrode must be baked for 1 hour at 350℃ before welding operation;
2. It is essential to clean up rusty, oil scale, water, and impurities on welding parts before welding;
3. Use short arc operation when welding. The narrow welding track is proper.
