Description: J707Ni is a low-alloy high-strength steel electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive) and can be welded in all positions. Deposited metal has good mechanical properties. Compared with J707 electrode, the main feature of J707Ni is that the low temperature toughness and crack resistance have been significantly improved.

Application: Used for welding low-alloy high-strength steel structures of corresponding strength levels, such as 14MnMoVB, WEL-TEN70 and Japanese HW56 and other low-alloy high-strength steel structures.

Chemical composition of weld metal(%):

 Mechanical properties of weld metal:

Diffusion hydrogen content of deposited metal: ≤4.0mL/100g (glycerin method) 

 I级      X-ray inspection:  I grade

 Recommended current:

Notice:

1. The electrode must be baked for 1 hour at 350 ~380℃ 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.
