Product description: 

SJ-101 is fluorine alkaline type sintered flux, Basicity factor is 1.6-1.8,Gray ball-type particles and its particle size is 2.0-0.28mm(10-60meshs),it can used with AC and DC.When DC welding ,the welding wire should connected to the positive electrode, the maximum welding current up to 1200A.The welding arc stability, easy to slag off, deposited metal of pure, weld appearance, has good moisture resistance, high impact toughness at low temperature,The flux can meet the transportation, storage and welding process of the recycling use.

Usage:  

With suitable welding wires(H08MnA.H08MnMoA.H08Mn.2MoA.HioMn2),it can welding a variety of low alloy structural steel,used for important products’ welding, like the boiler and pressure vessel,piping etc,it also can be used for multiple wire submerged arc welding, especially suitable for large diameter vessel single-sided welding

Note:

1.Before welding should bake 2 hour with 300-350 degree.

2.Before welding must remove the rust,oil,water and other impurities.
