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:Production of flux (raw materials such as anhydrous ethanol, flammable substances, belonging to dangerous chemicals), whether the need for safe production license?
If there's too much dangerous stuff, you can't do it. It depends on what chemicals you have! Suggest handling!
Q:How do you confirm the spray status of the soldering flux?
Is soldering flux used for wave soldering? If it is, visual inspection can be, and then according to the tin after the furnace to be adjusted to achieve the best results
Q:Is there any corrosion in the soldering flux? How do you use it to solder?
Due to the strict restriction of solid content and corrosive flux, the welding performance is necessarily limited. In order to obtain good welding quality, new requirements for welding equipment must be put forward with inert gas protection function. In addition to the above measures, the cleaning process also requires more stringent control of the welding process parameters, including welding temperature, welding time, PCB, tin depth and PCB transmission angle. Different cleaning parameters of wave soldering equipment should be adjusted according to different cleaning fluxes, so as to achieve satisfactory cleaning effect.
Q:How does solder paste blanch after soldering?!
There is a problem with the solder paste, and you need to consult the manufacturer of solder paste.
Q:What flux is used for 1% silver wire?
Can help to buy some pens or buy low solid content of flux, if after welding residual, with cleaning agent.As for what flux well, I don't have a good answer for you, if you say I'm advertising, of course it is best not to sell the market to buy the best buy accessories, big brands, such as Alfa, 1000, Kester., is this a few international brands.
Q:Which is better, soldering flux or rosin?
1, good rosin, flux although convenient, with a certain corrosion, damage to circuit boards and components.2, flux (flux): in the welding process can help and promote the welding process, and has a protective effect, and prevent oxidation reaction of chemical substances. Flux can be divided into solid, liquid and gas. The main auxiliary heat conduction, removing the oxide, reduce the surface tension of welding material, welding material removal is surface oil, increase the welding area, prevent oxidation and other aspects, in several aspects of the key role of the two is: "to remove oxides and" to reduce the surface tension of welding material".3, rosin, refers to pine resin as raw material, through different processing methods of non volatile natural resin. Rosin is an important chemical raw material, widely used in soap, paper making, painting, rubber and other industries.
Q:How to judge the quality of a soldering flux?
Specific gravity. The specific weight should be 0.80-0.82
Q:What kind of soldering flux, because the welding surface is the key
Do not use the wave carrier, it is not to use high temperature yellow tape paste it? We use the same side of the country's well-known brands, but also good
Q:What happens when soldering fluxes are always sprayed out of flame brazing?
Isn't there a baffle?
