Welding

1.It is a type of Mid-Mn High-Si Low-F smelting flux.

2.Green to celadon with the of 7-20 meshes. It is like transparent vitreous.

3.Application: particularly used in the electroslag pressure welding for vertical rebar.

4.Advantage:It's easy to start arc, to build slag pool, and to slag off. The process of electroslag is stable. What's more, the surface is bright and its fore rate is high.

7.Cautions:

Before the construction of reinforced do try to pull parts used to determine the best parameters.

Reinforced fluctuation concentric, two plane to level off.

Should not dirt, grease joint and high corrosion.

Flux should not in the rain, H2O ≤0.1%

The power supply voltage change should adjust welding standard.

Q: Urgently!!! The plating of nickel plating meets the soldering flux when soldering. The reaction result in the surface of the electroplated parts is pale yellow and black. How can I deal with this problem effectively and make the electroplated parts come back to its original appearance? Online results: There are two possible reasons that flux change nickel layer:First, nickel layer of high temperature discoloration, the need to use acid activation, sulfuric acid and hydrofluoric acid can be used;Two, the flux of organic residues, which need to be cleaned with organic solvents, such as alcohol, gasoline, acetone and so on.

Q: Wash the water after washing, very sticky after washing, alcohol after washing pan white: After welding, usually with DT-78A or DT-68A to clean, these two cleaning agents in the electronic plate cleaning is generally relatively clean, and manual cleaning, pay attention to the direction of the product.The flux is in the process of welding to welding and insulation effect of the welding flux in the later, and no clean flux is not only to help, and after welding surface clean, no special requirements without flux plate washing.Advantages of no cleaning flux:1., good weldability, solder joints are full, no welding beads, bridges and other undesirable2. non-toxic, no pollution to the environment, safe operation3. after welding, the board surface is dry, non corrosive and non stick4. after welding, on-line testing ability5. match the material of SMD and PCB board6. after welding there is a specified surface insulation resistance value (SIR)7. adapt to welding process (dip, spray coating, foam, etc.

Q: Is the flux poisonous?: On line but not tin solder resist yo problem is written: chemical products lead-free flux on the body is more or less a lot of influences of flux type Oh, see what is flux components, and then to find

Q: Solid rosin can be placed inside the flux or solder it?? What's the function?: What do you want to achieve? I'll fix it for you.

Q: What occasions are they used? What do we usually use when welding with iron iron?: The main composition of flux and its function:A. activator (Activation): the composition is mainly used to remove the PCB copper film pad surface and parts of the welding parts of the role of oxidation substances, but also has to reduce tin, lead surface tension effect;B. thixotropic agent (Thixotropic): this component is mainly to regulate the viscosity of solder paste and printing performance, play a role in printing to prevent trailing, adhesion and other phenomena;C. resin (Resins): this component is mainly used to increase the adhesion of solder paste, and to protect and prevent the re oxidation of PCB after welding. This component plays an important role in the fixation of parts;D. solvent (Solvent): this component is the solvent of the flux composition. It plays a uniform role in the mixing process of solder paste, and has a certain influence on the life of solder paste;

Q: Influence of flux granularity on process: In simple terms, the degree of fine particle flux flux welding the weld smooth, large particle flux welding the weld rough, sometimes seen in the weld surface pits, but the flux particles too small, welding when the exhaust air is blocked, the surface or near surface gas hole to weld, so now the use of granular flux the basic 10~40 head in this range

Q: How to use the photovoltaic flux?: Method for using photovoltaic flux:The use of foam, the liquid flux is higher than that of PV foam tube of about 3 cm, adjust the pressure of air compressor to control the foaming height, remove excess flux by air, to give full play to the PV flux solution, PV flux in work should pay attention to check the concentration of flux, adding appropriate diluent to keep flux flux of photovoltaic PV the activity should be checked regularly and discharge the moisture in the air for air compressor, the replacement of new PV flux flux generally work in foaming groove for 48 hours after.

Q: What component of a soldering flux conducts electricity?: It is the main component of solder paste

Q: What are the hazards of soldering flux?: 1, the substrate has a certain corrosive;2, reduce conductivity, resulting in migration or short-circuit;3. Non conductive solid such as the contact part of the invading element can cause poor bonding;4, resin residue is too much, adhesion, dust and debris;5, affect the reliability of the product.

Q: What effect does flux add to rosin? Effect?: Rosin itself is weak, long before people is to help with rosin, and later with the development of electronic products and the quality requirements, also slowly so that a small part of the cost of raw material, rosin flux.Adding rosin flux, tin, but the surface is dirty, so in the process of using rosin, there are advantages and disadvantages. Do you want to use rosin mainly depends on the requirements of customers, to help decide.Flux (flux): a chemical that helps and promotes welding processes and has a protective effect and prevents oxidation reactions in welding processes. Flux can be divided into solid, liquid and gas. The main 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 and other aspects, in several aspects of the key role of the two is: "to remove oxides and" to reduce the surface tension of welding material".
