Welding flux SJ501

GUJIN® is a professional leader China Welding flux SJ501 manufacturer with high quality and reasonable price.  GJ.SJ-501 is an aluminum titanium type Agglomerated flux with a alkalinity value of 0.5-0.8, dark brown spherical particles, a loose loading ratio of 1.2g/cm³, a particle size of 10-60 mesh, and can be used for both AC and DC. The DC welding wire is connected to the positive electrode, and the maximum welding current can reach 1000A. When using this Submerged arc flux for welding, the arc combustion is stable, the weld formation is beautiful, and it has strong resistance to porosity. It is not sensitive to a small amount of rust and high-temperature oxide skin; It can transition Si and Mn into the weld seam, especially suitable for dual wire and multi wire high-speed welding; Due to its good slag removal, it is commonly used for welding corner seams.

Usage:

Submerged Arc Flux SJ-501 matched with welding wires such as H08A, H08MnA, and H08MnMoA, it can weld low-carbon steel, certain low alloy steel, and heat-resistant steel, such as ships, boilers, pressure vessels, etc; Especially used with high-speed welding.Especially suitable for double-sided single pass welding.

Cautions:

1.The oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.

2.Submerged Arc Flux SJ-501 must be baked at 300℃-350 ℃ for 2 hours before use.
