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:What component of a soldering flux conducts electricity?
It is the main component of solder paste
Q:How do you confirm the spray status of the soldering flux?
The state of atomization mainly depends on the flame color of the torch flame. Besides, the seam sealing state of the weldment surface is smooth, plump and so on.
Q:The reason why solder tin does not solder to solder (flux)
The reason is that the PCB pad is oxidized, while the removal of the oxide film BG in the soldering flux results in poor tin plating.Flux: flux, solder paste and also, there are two kinds of liquid, in metallurgy is clean in a chemically welded metal surface for soldering, brazing or welding material, positioning. The use of different metal welding flux is also different, for example: the use of ammonium chloride or rosin soldering; welding galvanized iron and other zinc surface material with hydrochloric acid or zinc chloride; copper brazing or welding to black metal with borax. The welding material is easy to adhere to the corresponding welding metal surface after melting at high temperature, but the metal surface is easy to form oxide layer at high temperature, so that the welding material is difficult to adhere to the surface. The flux is stable at room temperature and has a strong reducibility at high temperatures. It can remove the oxide layer on the metal surface. In addition, the solder in soldering and brazing process can also play the role of wetting agent.
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:Ratio of submerged arc welding wire and welding flux
The ratio of welding wire to flux should be 1:1.2--1.4. If it is the construction site water tank ring submerged arc welding, in the range of 1:1.6.
Q:Why is flux etching copper plate?
May be afraid of tin line will break when it?
Q:What welding wire and flux are used for submerged arc welding of austenitic stainless steel?
Generally speaking, the selection of welding rod can refer to the material of base metal, and choose the electrode with the same or similar composition as the parent material. For example, A102 corresponds to 0Cr19Ni9, A137 corresponds to 1Cr18Ni9Ti, and so on.Stainless steel, corrosion resistance of stainless steel with increased carbon content decreased, therefore, the carbon content of most stainless steel are relatively low, the maximum of no more than 1.2%, some steel Wc (carbon) or even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), which is corrosion resistant only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is lower, the maximum is not more than 1.2%, and the Wc (carbon content) of some steel is even lower than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), which is corrosion resistant only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
Q:Can Q345E and Q345B be soldered together? What flux and wire are used?
If there is no specific performance requirements, just want to connect them together, then using manual electrode welding, selection of basic electrode J507 or acid electrode J422 is ok.
Q:I want to ask, before the flux, solder paste and red glue unopened, in the fridge, and food can be put together? Is there any harm to the human body?
Must not, and very unhappy
