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: Welding point and button carbon oil on the same side, do not want to put into the jig.: Do not use wave soldering tools, use high temperature adhesive tape, but this way, viscose paper, adhesive tape will not be less investment. At the same time, the key is generally in the wave soldering after manual welding (your process seems unreasonable), because the keys can not be cleaned

Q: What is the brazing flux: When the flux of low melting point, called soldering, such as soldering; when the flux of high melting point, called brazing, such as brazingSoldering flux is usually a mixture of rosin as the main component. It is an auxiliary material to ensure the smooth progress of welding process. Welding is the main process in electronics assembly process, flux is used in welding materials, the main role is to remove the solder and flux of materials to be welded on the surface of the oxide, the metal surface to achieve the necessary cleanliness. It again to prevent surface oxidation during welding, reduce the surface tension of welding material, improve the welding performance of flux. The quality directly affects the quality of the electronic products.

Q: Can the flux soldering solenoid valve be maintained?: As long as the coil does not burn, it can be repaired, but it will not take long to suggest a replacement.

Q: What is the appearance of a solder pit in a sj101 flux?: Not clear about your problems, you can call the Shenzhen siristrong solder products factory consultation, can be found online contact

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: Remove the flux residue on the heating platform: The heating flux on the platform under high temperature continuously, almost residue carbonization and oxidation flux, flux contact platform will become black or black and yellow, it is unable to use clean ordinary method. The first to use chemical solvents (ethanol or toluene, acetone and so on) the flux residue clean, the oxide layer on top of the platform color is deep, wiping several times with dilute hydrochloric acid 5%-10%, can a new clean, then rinse clean. Attention must be put on protective gloves and protective glasses, so as to avoid accidents.

Q: Rosin is an insulator. Why is rosin used as a soldering flux in industry? Doesn't that lead to electricity in the wire? When the teacher taught me, he always coated the wires with a layer of rosin, coated with a tin of solder, and soldered the wires to the circuit board with solder. In this way, the rosin on the head does not conduct electricity, will it not affect the circuit?: As the metal surface and air contact, it will produce a layer of oxide film, the higher the temperature, the thicker the oxide layer. This film to prevent liquid solder on the metal infiltration like glass coated with oil will make water cannot infiltration glass flux is a kind of special material to remove the oxide film also called flux rosin in solder wettability. The metal can remove the oxide film on the surface... Now there are special solder paste, rosin less used.

Q: How can I test the acid value of the flux? What criteria do you use? Which agency does it go to?: Scaling powder！！ Is it for cast welding machines? I don't know how to test this, but I know this can cut the skin off your fingers. This stuff is very corrosive

Q: I bought the wrong one and asked for advice: Flux is used to assist welding, and washing water is used to clean the soldering flux. How can the flux be used when washing the board?
