- Q: What welding flux for electroslag welding material Q345B
- H10Mn2Mo (A) is used as the welding wire for electroslag weldingFlux selection HJ431Electroslag welding refers to the use of electric current through the slag generated by the heat of resistance, as the heat source, the filler metal and base metal melting, solidification, forming a solid connection between the metal atoms. At the start of the weld, the welding wire and welding short circuit arc groove, constantly adding a small amount of solid flux melts by arc heat, the formation of liquid slag, slag to reach a certain depth, increasing the feed rate of welding wire, and reduce the voltage, so that the welding wire into the slag pool, arc extinguished, and transferred to the electro slag welding process.It is the shortcomings of the large heat input weld joint, long residence time, near easily overheat under high temperature, the weld metal is cast microstructure of coarse crystalline, low impact toughness, welding after welding generally require the normalizing and tempering heat treatment.Electroslag welding is suitable for the joint of vertical or oblique (inclined in 4:1 range) steel bars in cast-in-place concrete structures, especially for columns and walls of high-rise buildings. The utility model is also suitable for thick plate splicing, vertical welding of a blast furnace in a steel plant, welding of large castings and forgings, and tubular electroslag welder mainly used for the welding of the partition of the steel structure of the building and the welding of flanges. In PWR nuclear power plant, the core of the reactor pressure vessels (RPV, low carbon alloy steel) stainless steel lining of electroslag welding.
- 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: Is the flux poisonous?
- The flux and is toxic, flammable, strong solder you can answer more questions
- Q: Why does the flux leak?
- The main reason is that the formula of the flux is unreasonable, and the content of organic acids and halogens is over standard, which leads to the decrease of the insulating impedance of the residue and leakage of electricity.
- Q: Solid rosin can be placed inside the flux or solder it?? What's the function?
- In general, rosin is a kind of flux used in electronic welding. It belongs to resin flux and has better effect than inorganic and organic fluxes. It is one of the most commonly used fluxes.Rosin is put in solid flux, the welding flux has 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 of "and so on, especially the first two, to improve the welding the effect of great help.
- Q: Because of my article is aluminum solid core, it is not with the flux? Is there any need to add it?I am the aluminum tube in the fridge and welded to the aluminum tube
- The aluminum tube and the aluminum pipe welding can be welded with ALCU-Q303, and can search the "copper aluminum welding video" in the Baidu net ALCU-Q303 how to weld the copper aluminum pipe joint
- Q: When welding, the mold has the crystallization, is not easy to clear, whether has the crystallization flux?
- The battery does not need any soldering flux when casting welding.
- Q: Remove the flux residue on the heating platform
- Did you buy detergent in your house? Or washing board water? Yes, try it.
- Q: Silver copper phosphorus brazing welding electrode and a copper tube with no flux? Which one, or not?
- The copper tube and the copper tube do not need welding flux when welding the copper tube and the brass piece
- 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.
