Description: J707 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. When necessary, weldments can be preheated before welding and tempered after welding. Application: Mainly used for welding 15MnMoV, 14MnMoVB, 18MnMoNb and other low-alloy steel structures. The welded structure can work under the condition of welding or tempering (500 ~ 650 ℃). Chemical composition of weld metal(%):
