J707

According with GB E7015-D2
Corresponding with AWS  E10015-D2


Introduction: J707 is a kind of low-alloy high strength steel electrode with low-hydrogen natrium type coating. DCRP (Direct Current Reversed Polarity). All-position welding. If necessary, weldments should be preheated before welding and tempered after welding.


Uses: Mainly used for welding low-alloy steel structures with corresponding strength. Some after-welding structures like 15MnMoV, 14MnMoVB, 18MnMoNb, etc. can work under as-welded or tempering (550-650℃) conditions.

Instructions:
1.The electrodes must be baked under about 350℃ for an hour before welding, and used as soon as baking is completed.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
3.When welding, short arc must be used and stringer bead is suitable.
