Superior Quality of Full Mixed Blended Flux E7018.

1)All position welding

2)Extra low hydrogen potassium type coating.

We are a experienced factory specailly manufacturing mixed flux and various welding electrodes.

1) To select superior quanity of raw materials .

2) Our engineer designed particular formulation of flux in long term practice.

We would like to design formulation according to client's welding electrodes.

E7018 is an outstand quality all positon welding electrodes covered with extra low hydrogen potassium type coating for welding high tensile steels and low alloy steels. It's nominal welding efficiency is about 110% due to iron powder is contained.The weld metal shows an excellent low temperature toughness and high crack-resistance.

Application: It is widely used in important projects of ships ,boilers, high press vessels, bridge, skyscrapers,offshore drilling platforms,nuclear powder stations etc.

Q: What welding flux for electroslag welding material Q345B: H08Mn or H10Mn2345 material with Mn, if it is in welding technology melting mouth electroslag welding machine, welding wire with flux is 2.5, 431, if it is in welding technology with wire electrode electroslag welding, welding wire is 1.6, with Mn and Mo, the flux is generally JF600, if not, you can use 431 instead

Q: The core wire twisting wire peeling after soldering, using disposable flux, lead-free solder, tin products place several days will be black, what is the problem? How to solve?: Where the tin is stained, the product is oxidized,Abnormal handling of the product: re - oxidize the product to the tinIf the terminal is to solve this problem, only professional wire flux will be changed

Q: I made a soldering box for myself. The stainless steel had a problem. After that, it lost a lot of soldering flux. I only took some sticky things. Please ask the teachers. What's the problem?Thank you for your answer, I have done an experiment, the general rose in this flux box, the solder has only changed color, not volatile, because previously rose fixed box role: The flux box is used to hold the soldering flux, not to preserve the soldering flux. Your tightness is too bad, of course, the solvent may not be good, volatile too quickly.

Q: The stainless steel ring is dipped in Rosin when soldering, and there is a yellow stain on the surface. After washing with alcohol, there will be obvious marksThis regular code can be wiped off completely. It can not be polished: Try toluene and dichloromethane (poisonous). Stainless steel cleaner (with polishing) is not allowed". Use Baidu Search

Q: In the process of producing pressure vessel, if we know the break angle a, open the V gap with a flat edge, the edge height is h, the crack depth is H, and the gap of the weld is B. How do we calculate the total flux required for the L long bead? If detailed calculation formula is the best. Thank you: When the wire is determined (usually depends on the steel welding), supporting the use of the flux is a key material, it directly affects the mechanical properties of weld metal (especially plasticity and low temperature toughness), crack resistance, welding defect rate and welding productivity etc.. The match weight ratio between welding wire and flux is welding wire: flux =1.1 to 1.6, depending on type of welding joint, type of welding flux and welding specification parameter. Compared with the flux melting, sintering flux amount is saved, can use less about 20%.Our country uses flux at around 50 thousand tons, of which about 70% is smelting flux, and the other is non smelting flux. Developed countries in Europe and America are mainly non smelting flux, about 80% and more than 90%, but there are still smelting flux production, sale, smelting flux, this lasting productivity related to some of its inherent characteristics.

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: Solar photovoltaic, how to blow welding tape, that is, to weld the band to the flux, and then fish out drying, and seek specific operations and some skills!: Soak the interconnecting bars in a soaking box filled with flux for 3~5 minutes, remove and dry (120 minutes, 5 minutes) or blow dry. The flux should be soaked with a fully uniform interconnect bar. (it is recommended that the flux surface exceed the interconnect surface 1cm) when soaking. Note that the interconnect bars of different lengths are separated. How can they be written in 100 words?

Q: Influence of flux granularity on process: The more particles, the less strong welding mouth.

Q: What subjects does the flux belong to in the accounting voucher?: Auxiliary production cost

Q: How to use aluminum welding flux?: Aluminum welding flux in the electrode and electrode welding together on the line.Cleaning method of 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.

With good skill, advanced equipment, strict management and hard work of our staff, we specially manufacture high quality of welding products. Our leading product has passed the approvals of the authorities at home and abroad. The quality of our products has reached international leading level. Our products have been used in many areas such as shipping, bridge, engineering & machinery, chemical industry, pressure vessel and architecture.
