- 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
- When the wire is determined (usually depends on the steel welding), supporting the use of the flux is a key material, it directly affects the mechanical properties of weld metal (especially plasticity and low temperature toughness), crack resistance, welding defect rate and welding productivity etc.. The match weight ratio between welding wire and flux is welding wire: flux =1.1 to 1.6, depending on type of welding joint, type of welding flux and welding specification parameter. Compared with the flux melting, sintering flux amount is saved, can use less about 20%.Our country uses flux at around 50 thousand tons, of which about 70% is smelting flux, and the other is non smelting flux. Developed countries in Europe and America are mainly non smelting flux, about 80% and more than 90%, but there are still smelting flux production, sale, smelting flux, this lasting productivity related to some of its inherent characteristics.
- Q:How about the soldering flux with the same side?
- The same side of the flux is only moderate, before the company is with the solid content is not too high, generally do not have to worry about the flux will cause adverse consequences, the control is safe in the following 60ML/MINIn welding, compared with foreign flux, a little bit worse, usually a little more than tin, see what you do products
- 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:What is a soldering flux?
- Flux: an agent used to insulate oxygen from oxidizing metal emulsions, including inert gases and low melting point substances. At the same time, there are increasing the different proportion of metal solution affinity, and insulation effect, such as borax and so on. Different fluxes are chosen according to different requirements.
- Q:Do solder paste fluxes make profit? How about profit?
- As long as the electronics industry, the general needs of the factory, do not want to use your, it depends on your own skills.
- 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'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:I have 52 degrees of liquor (now home to drink the rest of the O (a _ a), O~) and refined rosin, how much is the allocation ratio. Look, someone uses 1:1 on the Internet. It doesn't seem to work. You must do it or understand it. No irrigation. Good answer, 10 points. By the way, am I pure alcohol?.
- Ha,,, may 52 degrees slightly low, with the best 56 degrees or net.
- Q:What occasions are they used? What do we usually use when welding with iron iron?
- Solder PCB board will use solder paste. On other occasions, usually not
- Q:What are the commonly used fluxes?
- The most used is rosinThe flux function: rosin resin and surfactant flux in the production of chemical reaction at a certain temperature, can remove the welding metal surface oxidation film, and rosin purpose and can protect the surface of metal shed no longer oxidation at high temperatures. Flux can reduce the surface tension of molten solder, and it is beneficial to wetting and diffusion of solder
