Low Alloy Steel Welding Electrode
J607
GB/T E6015-D1
AWS E9015-D1
Description: J607 is a low-alloy high-strength steel electrode with a low-hydrogen sodium coating. Use DCEP (direct current electrode positive), and can be welded in all positions.
Application: Used for welding medium carbon steel and low-alloy high-strength steel structures of corresponding strength, such as Q420, 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.
