Description: AK-J707RH is an ultra-low hydrogen high toughness high strength steel electrode with low hydrogen sodium type
coating. With DC reverse connection,all-position welding can be performed. The welding process performance isexcellent, the arc is
stable, the spatter is small, the slag removal is easy, and the welding seam is beautiful. The cold bending, crack resistance and
explosion resistance of the welded joint are good, and the weld metal has good plasticity and toughness.
Application: Suitable for welding low alloy steel structures with tensile strength equivalent to 690MPa.
