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: In welding, do you want to re engineer the welding process if the change of the flux grade, such as SJ101, becomes SJ301?
- Yes, flux is the primary factor and needs to be re evaluated after the change
- Q: How can I use the submerged arc welding flux?
- There are many holes and the current is big. The flux can be screened and can be used again. I am the leader of the automatic welding group of the boiler factory. I believe it
- Q: The stainless steel ring is dipped in Rosin when soldering, and there is a yellow stain on the surface. After washing with alcohol, there will be obvious marksThis regular code can be wiped off completely. It can not be polished
- Stainless steel welding has not been heard to use rosin flux ah. Do not know what specific stainless steel material you?However, due to the large heat welding of stainless steel welding itself, the weld edge will produce a layer of red or black oxide layer. The welding of stainless steel pipe, need to charge protection of Ar gas tube is in, in order to prevent the emergence of this oxide layer. Usually the pipe outside slightly the oxide layer on the surface of polishing sheet for grinding off OK.Does not recommend the use of rosin, because in the process of welding, high calorie, rosin as organic solvent, containing C and H ions. Hydrogen ions are easy to crack, carbon and stainless steel in Cr ion can happen carbonation precipitation of chromium carbide, corrosion resistance of stainless steel.
- Q: The manual is 63/37 260 welding tin furnace temperature after other joints are not only full of gun patch due to the cost of tin is used disposable flux please analyze the reasons in detail a bit if there is a better solution
- The reason is that the PCB chip pad oxide, and flux in BG lead to remove the oxide film on the tin side, Fu Xinda technology to provide professional hand dipped flux samples for your test!
- Q: What occasions are they used? What do we usually use when welding with iron iron?
- The main composition of flux and its function:A. activator (Activation): the composition is mainly used to remove the PCB copper film pad surface and parts of the welding parts of the role of oxidation substances, but also has to reduce tin, lead surface tension effect;B. thixotropic agent (Thixotropic): this component is mainly to regulate the viscosity of solder paste and printing performance, play a role in printing to prevent trailing, adhesion and other phenomena;C. resin (Resins): this component is mainly used to increase the adhesion of solder paste, and to protect and prevent the re oxidation of PCB after welding. This component plays an important role in the fixation of parts;D. solvent (Solvent): this component is the solvent of the flux composition. It plays a uniform role in the mixing process of solder paste, and has a certain influence on the life of solder paste;
- Q: What are the commonly used fluxes?
- To help dry flux, rosin rosin alcohol. 15 grams of 70 grams of bromide anhydrous alcohol salicylic acid 15 grams...Neutral flux, Vaseline 100 grams, triethanolamine 10 grams, anhydrous alcohol 40 grams. Water 10 grams of acid...Acid is not suitable for welding circuit boards, this can be usedThe most commonly used are rosin, solder paste,
- Q: How to choose welding rod, welding wire and flux
- Selection of flux must be carried out simultaneously with the choice of welding wire, because of the different combinations of flux and wire, it is possible to obtain different properties or different chemical composition of deposited metal. Flux and wire used for submerged arc welding are usually selected according to the material of the metal being welded and the performance requirements of the weld metal.
- Q: Say alcohol, then alcohol is industrial or medical, or do not pay attention to ah?I just made some today, but why is the rosin insoluble in it? It's always settling. It doesn't work. How can I get it? I can't wash it off. It's disgustingNo matter how I clean my hands, I'll do something about itThe point is, I hope the kind person can tell me how to mix the flux with video, so I can understand it more easilyThank you very much
- You can buy that kind of wire with rosin inside it. You don't need to dip it in one side with the rosin
- Q: The flux is sprayed on the PCB board. There is a lot of yellow on the solder joint. Which is the reason for the flux?
- There may be problems in the spraying process, or it may be the quality of the soldering flux. This is also an experiment to do the analysis of defective products
- Q: When the cylinder is preheated, the welding temperature is about 170 degrees Celsius. The welding time is 2 hours. The time of hydrogen removal is about 600 DEG C. Why did the penetration crack occur? If you want to change the wire flux, what should be replaced?
- This wire does not normally require hydrogen removal, etc. if it is Cr_Mo steel welding, you will need these steps (hydrogen removal, etc.).600 degrees, usually with a special heat treatment equipment, ordinary flame heating, you can not maintain such a high temperature. You can test the ring seam when you are heating. Is the temperature very uneven around it?.The material and thickness of base metal? The base material of this welding flux should be Q345 and so on. If it is thick enough to keep warm, there will be no problem between the interlayer and the rear heat.If the parent material is Cr_Mo steel, then there is no crack in the crack, and you use the wire is not correct, even if used for the right, this material is also prone to cracks.
