3.Grain size:of 8-40(2.5-0.45mm) and 14-40(1.5-0.45mm) meshes
4.Current:alternating or direct current(welding wires must be connected with the positive electrode when direct current is used)
Usage:
1.for low-carbon and low-alloy steels like 16Mn and 15MnV, as well as ships, boilers and high-pressure vessels[applied to welding wires such as H08A(AWS EL8), H08MnA(AWS EM12) and H10MnSi(AWS EM13K)]
2.for electro-slag and copper welding.
Cautions:
1.The oil stain, moisture, iron rust and other impurities must be removed from the surface;
2.Flux must be baked under 250~300°C for 2 hours before welding.

- Q:What is a soldering flux?
- Which can improve the electronic components soldering agent, can make strong bright spot,
- Q:How do you clean the soldering flux when you are not careful with it?
- Conditional first washed with alcohol, and then wash with soap, no alcohol around, direct cleaning with soap can also be
- Q:What is sintered flux?
- Sintered flux is a kind of high quality, high efficiency, energy saving and environmental friendly flux. The welding flux is smokeless, tasteless, arc free and without spatter when welding. The manufacturing process has no environmental pollution, low energy consumption, the use of raw materials. The preparation of scientific spirit full of sintered flux, welding process, strong adaptability, can be used for welding of thin plate, angle weld and super standard, high speed, multi wire, anti blowhole, narrow gap, deep groove under various working conditions, good slag detachability, weld good forming. Most of the sintered flux products are spherical and granular, which facilitates the delivery and recycling of solder flux in the welding process.
- Q:For example, the 7300 card chip, the oxidation of the fierce, and ordinary welding did not work, with 8205 plus welding can not blow the chip, and finally blown out, the normal situation of welding, it is easy to blow
- You can try the same side maintenance special flux
- Q:What are the roles of flux in soldering?
- Play a catalytic role in speeding up solder melting.
- Q:How to choose welding rod, welding wire and flux
- Selection 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.
- 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: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
- Previously, we have been submerged arc welding according to the quality of wire 1.4 times, may be a bit moreRecently, with pole overlaying welding, it has been found that the ratio of flux and welding band 0.9 is enough
- Q:Welding point and button carbon oil on the same side, do not want to put into the jig.
- Do not use the wave carrier, it is not to use high temperature yellow tape paste it? We use the same side of the country's well-known brands, but also good
- Q:Can Q345E and Q345B be soldered together? What flux and wire are used?
- Sure。 With H10Mn2 wire and flux SJ101
