Introduction：
WD-SJ101 is a fluoro-alkali type sintering flux with an alkalinity of about 1.8. It has the appearance of gray-brown 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 pole.

 

Applications：
With appropriate welding wire (such as H08MnA, H10Mn2, H08MnMoA, H08Mn2MoA, etc.) can weld a variety of low-alloy structural steel, such as ship hulls, boiler pressure vessels, pipelines, etc. It can be used for multi-layer welding, double-sided single-pass welding, multi-wire welding and narrow gap submerged arc welding.
