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:How about the soldering flux with the same side?
Flux can not be good or bad, comments can only say that it is not suitable. No matter what the flux, as long as suitable for their own is the best, in the same industry, Yantai solid light liquid flux has a higher reputation, it is recommended to use.
Q:How to use the photovoltaic flux?
The welding belt and the battery sheet are connected together and belong to the function of auxiliary welding. Before soldering, the soldering flux is applied to the grid line of the battery plate, and the solder on the welding band is easy to stick on the battery sheet.
Q:How do you remove the soldering flux on the PCB circuit board? The use of absolute ethyl alcohol is useless
Ethanol causes polishing treatment.
Q:Is flux harmful to people's health?
No, that's just general combustion support
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.
Q:The reason why solder tin does not solder to solder (flux)
The reason is that the PCB pad is oxidized, while the removal of the oxide film BG in the soldering flux results in poor tin plating.Flux: flux, solder paste and also, there are two kinds of liquid, in metallurgy is clean in a chemically welded metal surface for soldering, brazing or welding material, positioning. The use of different metal welding flux is also different, for example: the use of ammonium chloride or rosin soldering; welding galvanized iron and other zinc surface material with hydrochloric acid or zinc chloride; copper brazing or welding to black metal with borax. The welding material is easy to adhere to the corresponding welding metal surface after melting at high temperature, but the metal surface is easy to form oxide layer at high temperature, so that the welding material is difficult to adhere to the surface. The flux is stable at room temperature and has a strong reducibility at high temperatures. It can remove the oxide layer on the metal surface. In addition, the solder in soldering and brazing process can also play the role of wetting agent.
Q:Who has electronic factory alcohol, washing board water, soldering flux, wiping machine water four kinds of MSDS to me, thank you, any document will do, PDF can also
You really save it, what version will do, people can do it, you can use it? Do it yourself, your own product parameters are more clear, our company is doing their own drops.
Q:Excuse me: why does the chip capacitor touch the soldering flux and it doesn't work?
Are you sure the capacitor is broken? I don't have much experience in this area. But if the flux is too high or the pad is oxidized high and the melting time is insufficient, the problem will be obvious
Q:Where will the industrial flux be sold?
Large electronic materials market
Q:What is the density of the soldering flux?
On the flux density due to flux for different products.But usually between 0.79-0.93.
Our company has powerful technical force and qualified special group for developing products as per customer. The product have passed the approval of China Certification System, ISO9001:2008 Quality System, reached international leading level and have been sold to many countries and regions like South America, Southeast Asia, Middle East etc. Guaranteed with the reliable quality and after-sale service, you will be delighted to find that imported directly from us is so easy and simple as you buy from your local suppliers but with very competitive prices and more choice.
