Welding Accessories Welding Electrode E7018
E7018 Welding Electrode is an iron powder, low hydrogen type welding electrode used for welding 490 MPa class high tensile steel.
The weld metal has excellent mechanical porperties, toughness and crack resistibility. E7018 contains mush ironpowder in its coating and highly efficient welding can be conducted.
• Much iron powder contained in the coating gives high efficiency.
• Produces the weld metal of excellent toughness and crack resistibility because of the characteristic peculiar to the low gydrogen type electrode.
• Good with both AC and DC.
• All position welding for 490 MPa class high tensile steel is performed, in the fields of ship building, machine and steel structural fabrications.
Product is available in Size 2.6mm, 3.2mm, 4.0mm, 5.0mm.
E7018 is a low-hydrogen electrode with a high deposition rate for mild steel.
-Superior welding performance with either DC or AC.
-Superior mechanical properties: constant tensile strength and high impact value.
-Superior crack resistibility.
- Q: 400A DC inverter welding machine, suitable for long welding electrode
- 3.2.................. But it depends on what you're welding
- Q: 2.5, 3.2, 4, 1 kilograms of welding wire, how many branches?
- 2.5 a pack, 4.5 kilograms, 230 or so
- Q: Welding specification whether welding rod needs experiment
- Need quality assurance from manufacturer
- Q: 3.2 how much is a package of bridge electrode
- This depends on what kind of electrode, such as J422 welding rod, 3.2mm package is five kg, the price is about twenty yuan. If it is J507 electrode and so on, the price will be higher, such as A132 and other stainless steel prices will be much higher.The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The core metal cored electrode, in order to ensure the quality and performance of the weld, there are strict rules on the contents of metal elements in the core, especially for harmful impurities (such as sulfur, phosphorus content, etc.) should be strictly restricted, better than the base metal. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.For welding of carbon steel and low alloy steel welding core, are mostly made of low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other components (see wire national standard GB1300 - 77). The reason of low carbon is a low carbon steel wire plastic, wire drawing is relatively easy, on the other hand can reduce the CO content of reducing gas, reduce spatter or porosity and increased weld metal solidification temperature, favorable for overhead welding. The addition of other alloy elements mainly guarantees the comprehensive mechanical properties of the weld, and also has some effect on the welding process performance and the removal of impurities.
- Q: What kind of welding rod used for cast steel?
- Cast steel can be divided according to the composition of low carbon steel, medium carbon steel, different components of the electrodes used is not the same, if it is a low carbon composition, the common electrode, such as E4303 (J422) on it; if it is steel components, should be used in high strength structural steel electrode, such as E5015 (J507) E5515 (J557), welding welding and preheating, to prevent cracks.
- Q: Why do I use J422 electrode iron rail welding after their split seam. Later, the use of 506 electrodes did not have such a situation, I would like to ask what the rail contains? Yes. Is my J422 electrode fake? And... Is it my technique? Maybe the rails contain special ingredients? The person who knows it will answer immediately, "why does the seam split itself?"
- J422 is a titanium calcium type coating, acid electrode, tensile strength is more than 420MPa; the mechanical properties of rail, which is an indicator of tensile strength, mechanical properties of the rail are as follows:Steel tensile strength /MPa elongation / rail tread hardness% center line (HB)U71Mn, UIC900A = 880, 260~300 = 10PD3, BNbRE = 980, 280~320 = 9EN260 = 880 = 10 260~300 seen from the rail, the tensile strength is more than 880MPa, but the J422 tensile strength is more than 420MPa, so they will split the weld. J506 electrode for low hydrogen potassium type coating is added on the basis of the J507 formula in the arc stabilizing agent amount, the main welding electrode equivalent strength steel, low-alloy steel, ship steel and pressure vessels, such as 16Mn, 09Mn2Si etc.. Belong to the high manganese steel electrode, is the implementation of the "national standard" GB98485 surfacing electrode, electrode, the work hardening is particularly high, which improves the Mo crack resistance and wear resistance, hardened up to HB = 450-500. Higher than the rail 320, so the 506 welding rod welding rail, welding seam will not split.
- Q: J422 electrodes are marked with "THJ422". What does TH represent?
- TH: Tianjin Bridge Welding Materials Group Co. Ltd. manufacturer brands. J: stands for structural steel welding rod. 42: two figures indicate that the minimum value of tensile strength of deposited metal is 42kgf/mm2 (412MPa), and the minimum value of the yield strength of deposited metal is 34kgf/mm2 (430MPa). 2: third digit "2" indicates that the type of coating is titanium calcium type, direct current or AC power supply.
- Q: What's the difference between two oxygen welding and common electrode welding? What are the advantages and disadvantages?
- Now, there are still two people suspected of welding costs?Do not know that science and technology is the primary productive force?!Said the first two welding material, welding wire electrode 8 dollars a kilogram, 6 yuan a kilo, looks cheap electrode.You have to see how much of the filler metal left in the weld after welding is equal to the price.1, the outside of the electrode coating, and finally the welding slag and protective gas, does not belong to the filler metal.2, each electrode has a welding rod head, at least 5 centimeters, have to throw away, does not belong to the filler metal.3, welding rod splash, splash of metal, does not belong to the filler metal.In addition, other costs, welding rod to dry, need oven, heat preservation barrel, heating electricity, throw away the welding rod.Let's talk about the same welding power, welding, welding heat input two is small, costs less power, more power inverter welder.What's more about efficiency and speed?.1, do not bake electrode, save time, minus a manual.2, do not change electrode, also need not from new arc, save time3, do not knock the welding slag off at least a coolie.4, for welding speed, two welding is three times of welding rod. (on this one, a welder can top three, you have to calculate how much money, artificial!)
- Q: Electrode E4300 what does it mean?
- 1, welding rod E4300 means.2, did you see the icon? Let me explain it to you.E - electrode,43- indicates that the minimum tensile strength of the deposited gold wire is 430MPa,0- indicates that the welding position is all position,Second, 0 indicates that the electrode coating is of special type.
- Q: What kind of welding rod does 1Cr13 steel plate use?
- 1Cr13 read: a chromium thirteen.Brand: G207; G217 (model: E410-15);Brand: A302; A307; A402; A407 (model: E309-16; E309-15; E310-16; E310-15) welding electrodes can be welded to the stainless steel material.Select the electrode diameter according to the thickness of the workpiece.According to the electrode diameter, packing box description, welding position and other factors, select the polarity of welding and welding current size.
