Q: What is the difference between A302 stainless steel electrode and A402 stainless steel electrode?: A302 is Cr23Ni13 stainless steel electrode titanium calcium type coating for welding, the same type of stainless steel, lining stainless steels (Cr19Ni9 low carbon steel and high chromium steel and high manganese steel) etc.. A402 is Cr26Ni21 pure titanium calcium type austenitic stainless steel electrode coating, for the same type of heat-resistant stainless steel under high temperature welding, can also be used for large steel hardening (such as Cr 5 mo, Cr 9 mo, Cr 13, Cr 28) and welding of dissimilar steel.

Q: In addition, when the basic electrode is DCEP welding, the hydrogen content is lower than that of DCEN?: Because of the alkaline electrode contains a lot of calcium fluoride (CaF), the decomposition of fluorine in the arc under the ionization potential of fluorine is high, not easily ionized, and the outermost layer of fluorine has seven electrons, cannot lose electrons to become positive ions, but easy to get electrons becomes negatively charged, if the answer is that will, fluorine ion mass to welding pool movement, so will increase caused by splash, arc burning instability. The reverse, however, and when using the reverse connection, positive ion electron in hydrogen, in the molten pool is formed on the surface of HF, the surface can be greatly reduced in welding seam hydrogen.

Q: What type of welding rod is used for welding 16MnD?: Using J507RH welding rod.DC reverse connection.Preheat about 100 degrees before welding.When the plate thickness is less than or equal to 20mm, the V type groove is opened and the U groove is used when the plate thickness is greater than 20mm.Current: Phi 3,2 welding rod A=130-150, Phi 4 electrode A=180-200, Phi 5 electrode A=230-250.Conditional, should be done after welding stress treatment.

Q: What kind of welding rod needs baking?: Ordinary carbon steel electrode without baking, it is necessary to roast pig iron electrode can improve the quality of welding electrode 2, the storage time is too long when damp, but not the core rust, coating without deterioration, electrode after drying, can keep the original performance and does not affect the use.The electrode drying conditions of various types of drug skins are as follows (reference value):The baking temperature of acid welding rod is 150~200 1HThe baking temperature of alkaline welding rod is 350~400 1HThe baking temperature of cellulose electrode is 80 DEG C and the temperature is 1.5 ~ 2HThe baking temperature of graphite type electrode is 200 1HNOUN interpretation:ElectrodeThe electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece. Consists of two parts covering and core wire. Depending on the melting of the crust and filling the metal into the weld, it becomes the main component of the weld metal, which is called a welding rod.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.

Q: Can ordinary electrode be used for welding cast iron?: Yes, just increase the current

Q: Welding Q345C steel plate with ordinary electrode?: Yes. Ordinary structural steel electrode can be used, but attention should be paid to the strength of the steel. Q345 steel corresponding welding rod should be 500MPa class, that is, E50 * * * or J50 * grade electrodes, such as E5003 (or J502), E5015 (J502) and so on.

Q: Where is the difference between 422 electrode and E50 electrode? HRB335 steel cage can use 422 electrode: Tensile strength is mainly different, HRB335 steel bar should be allowed to use 422 electrodes,

Q: What kind of welding rod is used to weld Mn13 steel plate with ordinary high quality structural steel?: At first glance it was copied. The first half is true, and the lower half is ZGMn13, that is cast steel Mn13. Landlord asked clearly, is rolling Mn13 welding, D256 or D266 welding rod can be, D256 cheaper, and welding layer wear-resistant; most commonly used manual arc welding is very good, gas welding and other methods are not, can not be welded. With A202, A302 welding rod can also, but not wear-resistant, only the role of connection. Shanghai Yao rate specializing in rolling Mn13.

Q: How do you make holes in the steel plate with the welding rod?: 1, the following general 10MM board directly to the plate electrode for an empty blow through, must further expand air through the air, need more air electrode with air to air around the suitable size, but the steel bottom board should be suspended, is conducive to the burning capacity of molten iron flow, general space only with electrode blowing, too small to empty is not blowing to using electric drill.2, 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.
