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:What kind of soldering flux, because the welding surface is the key
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:Use free cleaning flux and do not use boards?
I suggest you wash good Xintai solder cleaning plate with DT-78A water or cleaning agent DT-68A ultrasonic cleaning, welding surface water, flux residues should be caused by too much
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:What is flux and what is its use?
In the soldering of the circuit board, the solder is as follows: 1, reduce the point of solder. 2 increase the liquidity of the solder, the solder joints weld, and good surface gloss.The above is only the main function, and there are other functions (don't need to know)
Q:Where do I work with lead flux for chronic lead poisoning?
Lead flux is the flux used for lead solder, and the soldering flux itself does not contain lead.To worry is chronic lead poisoning lead tin lead in sublimation, poisoning and flux itself (chronic alcohol anesthesia)
Q:Why solder flux is needed for submerged arc welding?
First of all, submerged arc welding is also arc welding. Arc welding is characterized by the melting of metals. In the process of metal melting, if there is no separation from the air, there will be excess oxides in the weld, alloy elements are reduced, there are many nitrides and so on. In order to reduce the harmful effects of oxygen and nitrogen, the molten metal must be separated from the air during welding. The separation of liquid metal from air by means of gas and slag produced by flux.Role of welding flux:1) improve the electric conductivity of arc, make arc easy, stable arc;2) to form molten slag, to protect the transition droplets, to protect the molten pool, to cover the upper surface of the bead, and to avoid the excessive cooling of the weld;3) the metallurgical effect on the dissolution bath, between the metal and slag, through the ferromanganese and ferrosilicon reaction deoxygenation;4) alloying action, adding Si and Mn, Cr, Ni, Mo and other elements.
Q:Is flux harmful to people's health?
The flux inhalation toxicity to human body harm is extremely low, mainly is the brain central nervous inhibition, can cause dizziness and nausea, flux of high concentration can lead to loss of consciousness of human skin direct contact with liquid may cause mild skin irritation. Rinse with water. Flux to human eyes: 1.300ppm vapors irritate the eyes, and liquids can cause irritation to the eyes. If eating flux will cause sore throat, nausea and diarrhea. May be inhaled into the lungs and cause serious lung irritation when vomiting, destruction of lung tissue and chronic death: dissolve skin oils, long-term exposure may cause irritation. The main symptoms of dermatitis: nausea, vomiting, headache
Q:What flux is used in the casting welding of batteries?,
If the parts are cast welding as long as preheating can obtain good welding effect, the disadvantage is if there is a coating, the coating is easy to change, so you want to control a suitable temperature, we have been doing. Different fluxes have been tried, but in view of the ease of introducing impurities into the battery, they are not used at all.
Q:How about the soldering flux with the same side?
Flux can not be good or bad, comments can only say that it is not suitable. No matter what the flux, as long as suitable for their own is the best, in the same industry, Yantai solid light liquid flux has a higher reputation, it is recommended to use.
