Description of Welding Flux For Hardfacing: 

JN-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 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 of Welding Flux For Hardfacing:  

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, etc.


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 withHOOCr21Ni10(AWS ER308L) as the surface-layer welding band.



1.Impurities on the welding surface must be removed before welding, such as oil soil, moisture, iron rust, etc.


2.The flux must be baked for 2 hours under the temperature of 250-300°C before it is used.

Q:What flux is used for 1% silver wire?
It's OK to weld it with rosin ribs
Q:What happens when soldering fluxes are always sprayed out of flame brazing?
The temperature should be controlled well
Q:What flux should be used in the national standard for nickel plated products?
I think good east Xintai solder that depends on your product material, first sample
Q:Solid rosin can be placed inside the flux or solder it?? What's the function?
What is solid rosin? Isn't that just to protect the solder from being oxidized and to restore the solder that has been oxidized? So it's better to put it in the soldering flux. But this is not to say that it is not allowed to put in the stove inside, because the excess solder also need to protect and restore[answer added]:In practice, it is convenient to use rosin containing solder wire!
Q:How did the hand soak in the soldering flux?
First rinse with alcohol, then dry with a cloth and rinse with soap and water
Q:What are the concepts of solder paste and soldering flux, and their range of two is large
Solder paste: used for patch welding of circuit boards. Solder paste is a paste of a mixture of tin, silver, alloy particles and soldering flux.Soldering flux: a kind of auxiliary welding material. The main component is rosin. A surface oxide used to clean the metal of a welded part.These two substances are nothing at all!
Q:How do you distinguish flux from alcohol?It tastes about the same. What's the easiest way to distinguish between them in reality?
Some flux solvent can be used alcohol as solvent, but for lead-free solder, the welding temperature is 200-250 degrees, the boiling point of alcohol is too low, only as part of the mixed solvent, less amount. Because soldering flux must not be allowed to burn under welding temperature, you can distinguish it from this
Q:What brand of soldering flux is of better quality?
The United States ITW Chemtronics this brand is not bad, there are two agents at home level
Q:Excuse me: is the special flux for steel electroslag pressure welding called "residue"?
It's called the dregs, but there's no detail. The hardware store is available
Q:Remove the flux residue on the heating platform
The heating flux on the platform under high temperature continuously, almost residue carbonization and oxidation flux, flux contact platform will become black or black and yellow, it is unable to use clean ordinary method. The first to use chemical solvents (ethanol or toluene, acetone and so on) the flux residue clean, the oxide layer on top of the platform color is deep, wiping several times with dilute hydrochloric acid 5%-10%, can a new clean, then rinse clean. Attention must be put on protective gloves and protective glasses, so as to avoid accidents.
