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 is the difference between THJ506 welding rod and THJ422 electrode?
Fine, thanks for the answer
Q:What does "E7016" mean? What should I pay attention to when welding? Can I weld the pressure vessel (pressure 1Mpa)?
The electrode E7016 is American Welding Society AWS grades, the tensile strength of 470MPa, yield strength is 390MPa, the impact toughness of 100J (-50 C) section, the elongation is 30%, and the yield strength and tensile strength of the national standard J507 (E5015), so this electrode can replace J507 (E5015) electrode, is resistant to ultra low moisture absorption hydrogen electrode, excellent low temperature impact properties, using direct reverse, used for all position welding. Look at the electrode welding electrode has not expired, no quality problem, and then the electrode drying (350 DEG C for 1 hours), more than 3mm thick plate to groove, welding parts to rust, water, oil, dirt, can pressure vessel welding Q345R, 16MnDR strength is plate (as for the pressure, according to the the design requirements of 1MPa or greater pressure can be, but the thickness is different).
Q:Is the electrode electrically conductive?
An electrode is a conductor. The electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire. When welding, the welding core has two functions: one is the conduction of the welding current, arc energy converted into heat, two cores melting as the formation of the weld filler metal and liquid base metal fusion.Electrode welding, welding core metal part of the weld metal. The chemical composition of cores, directly affect the quality of the welding seam. Therefore, the steel wire used as the core of the electrode has its brand and its composition separately. If used for automatic submerged arc welding, electroslag welding, gas welding, gas welding and other welding methods for the filler metal, known as the wire.The coating layer is coated on the surface of coating is the core. In the course of welding, the coating is decomposed and melted to form gas and slag, which play a role in mechanical protection, metallurgical treatment and technological performance improvement. Composition of coating material: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.). For example, a light electrode without a coating is not easy to ignite the arc. Even if ignited, it can not burn steadily. In the electrode coating, usually contains potassium, sodium, calcium and other ionization potential of low substances, which can improve the stability of the arc, to ensure that the welding process continues.
Q:What's the difference between 507 and 422 electrodes?
507 is the welding manganese steel material, and the 422 is the general steel, that is, low carbon steel
Q:What wire and electrode are used for welding between s32168 and s31603?
Electrode grade: A132 or A022 (for high requirement) A022Wire type: ER347 or ER316L (for high requirement) ER316L
Q:What specification should be used for the three - step steel electroslag pressure welding electrode?
Welding wire with diameter 3mm
Q:What kind of welding rod is Mt -12?
MT-12 is a kind of low carbon steel welding rod, is Chinese more than 5 Minerals Import & Export Corporation Tianjin branch (hereinafter referred to as Minmetals Tianjin Corporation) brand products, its chemical composition is (%): C 0.09 Mn 0.40 Si 0.20 P 0.019 S 0.015Contrast chemical components, similar to J421, but higher than J421
Q:What electrodes can be used to weld boilers?
Welding furnace electrode is the most commonly used J422 and J507 two.Because often used in boiler manufacture, commonly used steel is: sheet --Q245R (20g) and Q345R (16Mng)Profiles --20# (GB3087) tubing 20# (GB699)Among them, the electrode matching Q345R (16Mng) is J507, and the other three kinds of materials match with J422 electrode.
Q:Welding Q345C steel plate with ordinary electrode?
Common electrode.You should say that the J422 structure of low carbon steel electrode, this kind of welding rod can only weld Q235 and lower grade low carbon steel material.Q345C belongs to low alloy steel (16Mn), only J50 series welding rod can be used. Such as acid welding electrode J502, the important structure using J506, J507 and other basic electrode.
