Q:How to choose welding rod, welding wire and flux
Selection of fluxSelection 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. The general said on structural steel (including high strength carbon steel and low alloy steel) welding, is used to match the strength of base metal wire; welding of heat resistant steel, stainless steel, is used to match with the composition of base metal wire; welding should be according to the requirements of surfacing technology, using the properties of selected alloys system and similar components of welding wire. Then choose the welding flux which is suitable for the product structure and can be well matched with the welding wire. In addition to the steel grades, the welding technology requirements and welding process factors should be taken into account when selecting the flux. Because of the different types of flux process performance, crack resistance and anti porosity performance is different. For example: welding of low alloy steel and high strength low temperature toughness good, it should be selected with high basicity flux, narrow groove butt welding thick multi-layer welds, should choose the good performance of the slag removal flux.
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 to fit soldering flux?
The rosin must be crushed, the alcohol should be used 99%, and the foam will be reconciled for some time. Medicine alcohol is 75% dissolved on the poor, long storage time, the concentration is even lower, more difficult to dissolve. The simple way is to heat the rosin and melt it into the alcohol, which is available at the moment. (video impossible to find)
Q:Why is flux etching copper plate?
The use of flux is:1. auxiliary heat conduction2. remove the oxide. Reduce the surface tension of the welded material3. remove the oil on the surface of the welding material and increase the welding area4. prevent reoxidation
Q:The flux is sprayed on the PCB board. There is a lot of yellow on the solder joint. Which is the reason for the flux?
LZ, I suggest you let the supplier re debug, see it, make some improvements in the preparation
Q:How do you distinguish flux from alcohol?It tastes about the same. What's the easiest way to distinguish between them in reality?
The general flux ingredients are rosin, of course, there is no rosin; sprinkle essence is only alcohol, cleaning mechanism is organic to organic, but the degree of cleaning is different
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:Method for producing rosin flux
Younger brother, to use more than 99.5 degrees, with 10% of rosin, on the line, ha ha!
Q:Is carbon dioxide gas shielded welding wire a flux cored wire?What is the explanation of solid cored wire?.
Now carbon dioxide gas shielded welding wire is divided into solid welding wire and flux cored wire.Solid wire: is H08 a bar or wire drawing to the specified size or not made of copper coated copper wire.Flux cored wire: the alloy powder is coated with a steel band to draw the wire to the specified sizeThey all use carbon dioxide as a protective gasIn general, gas shielded welding requires no soldering flux. Submerged arc welding is used only.
Q:What are the hazards of soldering flux?
Which is so serious? Let me show you the authoritative informationI've been doing this for ten years and I don't see any problemsWhen exposed to gas inhalation may cause dyspnea, dizziness, weakness, fatigue, nausea, headache and other symptoms. Pain reactions may be delayed for several hours.Constant exposure to the skin can cause tingling, skin wrinkling and dermatitis
