Description: HJ107 is a kind of smelting-type non-Mn mid-Si and mid-F flux, which appears grey blue pumice-like particles with the mesh of 10-60 (2.0-0.3mm) or 8-40 (2.5-0.45mm) and uses direct-current supply.
When it is used under higher electric arc voltage, the penetration is shallow, the arc is stable and the appearance of weld is pleasing to the eye.
The consumption of flux is low and it is easy to detach the welding slag. As it contains much CaF2 and Cryolite is also added to, its ability of anti-porosity and anti-cracking is greatly improved.
The ingredient Cr2O3 not only plays the floating petrochemical role but also reduces the loss of Cr in the stainless steel welding process.
Usage: Excellent clad layers can be gained when it is used in the build-up welding in conjunction with appropriate welding wires or solder strips, such as HOCr21Ni10(AWS ER308), HOCr20Ni10Ti(AWS ER321), HOOCr21Ni10(AWS ER308L), HOOCr24Nb, HOCr16Mn16.
It is suitable for the build-up welding of petrochemical equipments' corrosion-proof layers, stain-less clad layers and pressure vessels.
In conjunction with HOCr16Mn16, it can be used in the build-up welding of the track switch of high manganese steel (Mn13) and welding of Nb-contained stainless steel, ect.
Performance of Surfacing Layers: It can be used in the transition-layer welding in conjunction with HOOCr26Ni12 and in the build-up welding of 50mm-thick 18MnMoNb steel plate in conjunction with HOOCr21Ni10 as the surface-layer welding band.
Cautions: 1.Impurities on the welding surface must be removed before welding, such as oil contamination, moisture, iron rust, etc. 2.The flux must be baked for 2 hours under the temperature of 250-300°C before it is used.
