Q:Is there any environmental protection for soldering flux?: LZ, flux DXT-126A is environmentally friendly, environmentally friendly, environmentally friendly goods

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:Ratio of submerged arc welding wire and welding flux: Count on wastage and waste consumption, close to 1:1 in actual production.

Q:What are the roles of flux in soldering?: Remove the oxide skin and wet the matrix

Q:What is the soldering flux for aluminum: The principle is to use the soldering aluminum welding is not reliable, because aluminum is prone to oxidation. Regular soldering paste is fine if you want to weld

Q:I would like to manually wire lead end immersion tin, do not know what kind of flux selected, and the proportion of the flux does not know, check for a long time did not find, please heroes help ah?: No cleaning flux can be used. Manufacturers, models are many.

Q:What is the density of the soldering flux?: On the flux density due to flux for different products.But usually between 0.79-0.93.

Q:What subjects does the flux belong to in the accounting voucher?: Raw material auxiliary material (flux)

Q:What brand of soldering flux is of better quality?: Qualified flux is not good or bad, qualified flux is only suitable or not. Welding process, equipment, PCB (circuit board) quality, component quality, solder quality (tin content), operation staff proficiency are not the same, the choice of flux and requirements are also different.1, wave soldering should be selected for wave soldering flux, hand dip is another.2, using special flux spray coating process should be selected; using the process of hand dip coating is used spray type; foaming is another kind of.3, PCB, and the degree of oxidation of components is different, should be equipped with different activities of the strength of the flux.4, the purity of solder is different (tin content), should be equipped with different active strength of soldering flux.5, operation staff proficiency also determines the choice of soldering flux.Without proper selection of suitable flux, that is, the soldering flux can not achieve the best welding effect, and then the flux can only play the role of general flux.

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.
