    Introduction：
    WD-SJ102 is a fluoro-alkali type sintering flux with an alkalinity of about 3.4, with the appearance of gray spherical particles of 10-60 mesh (2.0-0.28mm). The flux in the welding process shows advantages as follows: arc stability; easy deslagging; beautiful weld seam formation; pure deposited metal; has a high low-temperature impact toughness. Welding can be used in both AC and DC, DC welding wire connected to the positive electrode.

     

    Applications：
    With the appropriate welding wire (such as H08MnA, H10Mn2, H08MnMoA) can weld a variety of low-alloy structural steel, higher strength hull structural steel, pressure vessel steel. It can be used for multi-pass welding, double-sided single-pass welding, multi-wire welding and narrow gap submerged arc welding.
