1.JN-HJ431 is a kind of high manganese and silicon, low fluorine fused flux
2.Color:red brown to light yellow
3.Grain size:of 8-40(2.5-0.45mm) and 14-40(1.5-0.45mm) meshes
4.Current:alternating or direct current(welding wires must be connected with the positive electrode when direct current is used)
Usage:
1.for low-carbon and low-alloy steels like 16Mn and 15MnV, as well as ships, boilers and high-pressure vessels[applied to welding wires such as H08A(AWS EL8), H08MnA(AWS EM12) and H10MnSi(AWS EM13K)]
2.for electro-slag and copper welding.
Cautions:
1.The oil stain, moisture, iron rust and other impurities must be removed from the surface;
2.Flux must be baked under 250~300°C for 2 hours before welding.

- Q: Urgently!!! The plating of nickel plating meets the soldering flux when soldering. The reaction result in the surface of the electroplated parts is pale yellow and black. How can I deal with this problem effectively and make the electroplated parts come back to its original appearance? Online results
- There are two possible reasons that flux change nickel layer:First, nickel layer of high temperature discoloration, the need to use acid activation, sulfuric acid and hydrofluoric acid can be used;Two, the flux of organic residues, which need to be cleaned with organic solvents, such as alcohol, gasoline, acetone and so on.
- 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?
- Where the tin is stained, the product is oxidized,Abnormal handling of the product: re - oxidize the product to the tinIf the terminal is to solve this problem, only professional wire flux will be changed
- Q: I am an electronics factory in charge, there is a sticky feeling dip to complete the PCBA, we use the non cleaning flux, do not know the film does not affect the quality of products, there is no need to wash the plate? Please expert advice!What should I do with it? Is alcohol all right? By the way, what welding wire do you use when you repair welding? I think the solder wire inside the flux will also have such a problem!
- This is my specialty. I have been in engineering and management in an electronic factory for over ten years. I have been doing technical and managerial work in 6 years. Most people give advice that is one-sided and does not take on practical significance. Of course, they are sincere in their zeal. Many electronic engineers have always been partial to flux knowledge, and they can not get some specialized knowledge of flux.Disposable flux is relative, you ask the supplier what is the definition of flux, that is disposable after welding without cleaning, it is dangerous to generalize. Several factors:1. what kind of products do you have (circuit characteristics: high voltage, low voltage, high frequency, low frequency)?.2. surface insulation impedance parameter of flux. (true, don't Scribble data)3. customer requirements for PCB surface cleanliness.4. working environment of products.Disposable solder wire resin material or resin solid content, good safety, can not accept the appearance of cleaning, improper cleaning will produce white powder.Flux welding after the residue of many, sticky hands (some cold after it does not stick) is not the reason for cleaning, this is the appearance of the layman's point of view.

- Q: What flux is better for welding copper strip?
- T-201D zinc alloy flux: it can weld copper flux and copper alloy flux with T-318 welding wire in the range of 150 DEG C to 320 DEG C.T-201D zinc alloy flux: it can be brazed with T-318 welding wire in the range of 150 DEG C to 320 DEG C.
- Q: Can the flux soldering solenoid valve be maintained?
- LZ, I suggest you take the repair shop there to see it, they know how to solve with you
- Q: In the process of producing pressure vessel, if we know the break angle a, open the V gap with a flat edge, the edge height is h, the crack depth is H, and the gap of the weld is B. How do we calculate the total flux required for the L long bead? If detailed calculation formula is the best. Thank you
- Submerged arc welding (including submerged arc welding and electroslag welding etc.) is a kind of important welding method, its inherent stable welding quality, high welding productivity, no arc and smoke rarely etc., make it become the pressure vessel and pipe manufacturing, box beam and other important steel production in the main welding method. In recent years, many new welding methods with high efficiency and high quality have appeared, but the application of submerged arc welding is still not affected. From the point of view of the proportion of deposited metal weight in various welding methods, submerged arc welding accounts for about 10%, and has not changed much over the years.
- Q: How about Jin Yuancheng's soldering flux and bath water?
- Have time to try for Western Beijing and integrity of electronic flux, plate washer water, especially after welding flux, if not clean, the water can be removed (non water-soluble flux), such as with warm water better. Type: CX414 / CX2012
- Q: 180 degrees of high temperature solder line, what flux effect is good?
- Landlord recommended wire rod bar to try to see it, dedicated
- Q: Is carbon dioxide gas shielded welding wire a flux cored wire?What is the explanation of solid cored wire?.
- Flux cored wire is used as flux cored wireSolid welding wire, as the name suggests, is no core, that is, wire drawn into welding wire, the surface will do some anti rust treatment, and sometimes copper plating, but certainly not anticorrosive paint. Paint is harmful to welding, it will produce pores
- 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
