4.25Kgs / PP woven bag

5.MOQ: 1 ton

 

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.

 

Cautions:  

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's the use of soldering flux?
The function of flux mainly includes auxiliary heat transfer, removing oxide and reducing surface tension of welded material". Soldering flux is usually a mixture of rosin as the main component, which guarantees the smooth welding process
Q:The soldering flux is good or good hydrochloric acid with sulfuric acidWhat is the sulfuric acid soldering flux or hydrochloric acid, which is easy to use?
Sulfuric acid and hydrochloric acid are not suitable for welding flux, you want to see what, in general the rosin flux is best, but you have to solder iron, such as enamel basin, a class of things can use the solder paste, can certainly use diluted hydrochloric acid to remove rust, welding effect will be better.
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
Alcohol, washing board water, soldering flux, MSDS for wiping machine water, we can press the latest regulations to come out, once to help you succeed. This needs to be done according to the specific circumstances, there is no ready-made online.
Q:How does solder paste blanch after soldering?!
Because the flux in the solder paste melts at high temperature and volatilize. When the solder paste reaches a certain temperature, the solder paste will melt and become liquid, and the flux will break down and diffuse on the surface and periphery of the tin bath. When the temperature drops, the tin liquid solidifies into tin, and the flux does not decompose and volatilize, and remains. The residue is usually yellow or white.
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:What is the soldering flux for aluminum
You can try soldering flux for Sn-Zn lead-free solder
Q:What is the difference between submerged arc welding flux and electroslag welding flux?
Submerged arc welding arc as the heat source, the flux mainly mechanical protection and metallurgy; electroslag welding in the slag pool as a heat source, in addition to the flux to protect the weld pool and the metallurgical effect, the main point is the thermal effect (slag resistance heat).The flux is also called flux, the definition is very broad, including molten salt, organic matter, active gas and metal vapor, remove the mother material and solder, refers to the third kinds of all substances used to reduce the interfacial tension of the solder and base metal.The functional part of the flux can be divided into three:1. Remove the oxide of welding surface, reduce the melting point and surface tension of solder, and reach the brazing temperature as soon as possible.2. Protect the weld metal from the harmful gases in the surrounding air when it is in liquid state.3 make the liquid solder have proper flow velocity to fill the brazing seam.
Q:What happens when soldering fluxes are always sprayed out of flame brazing?
Isn't there a baffle?
Q:The core wire twisting wire peeling after soldering, using disposable flux, lead-free solder, tin products place several days will be black, what is the problem? How to solve?
Flux acid value is too high, it is recommended to change the flux, or add appropriate amount of diluent. There may be tin impurities exceed the standard.
Q:Is there any environmental protection for soldering flux?
The flux itself does not contain the banned substance of ROHS, but REACH is not necessary.
