Q:Why not use 422 electrodes and 502 electrodes on the site? (Shanghai Kunming Railway): J422 welding rod is lower than steel standard. The strength of J502 is the same as that of steel bar, which is the reason of using J502 welding rod.Different reinforcement materials, the electrode tensile strength is not the same. The strength of the steel bar must be the same as that of the steel bar. The strength of the welding rod once, the steel bar will appear the weld organization intensity is low and the crack; the welding rod strength is higher than the steel bar, the welding seam and the reinforcement will have the bigger peeling force, similarly will crack.Model: J422, brand: E4303 belongs to titanium calcium type low carbon structural steel welding rod. It is suitable for low carbon structural steel with welding tensile strength Q235.Model: J502: E5003, belongs to titanium calcium type low alloy structural steel welding rod. Low alloy structural steel suitable for welding tensile strength Q345 grade.

Q:Does construction welding rod need to be re examined?: Don't want to do the material inspection (certificate and test report)

Q:When welding electrode, how to move the electrode, can you point it in detail?: What is the welding rod welding electrode Nie - composite motion: 1, which the feed movement of butt welding electrode2, the electrode moves along the center of the weld3, the repeated movement of the welding rod on the transverse direction of the weld or other ways of moving the strip

Q:How many kinds of welding rod do you have?: The electrode use is divided into 9 types: structural steel electrode (including carbon steel and alloy steel), molybdenum and chromium molybdenum steel electrode, stainless steel electrode, welding electrodes, low temperature steel electrodes, cast iron electrode, nickel and nickel alloy electrode, copper and copper alloy rods, aluminum and Aluminum Alloy electrode.

Q:Question Q235 weldability of carbon steel. What are the welding characteristics of those electrodes?: Preferably 58-1 basic electrode, the welding rod has high tensile strength, good toughness, can be AC and DC, all position welding

Q:What specification should be used for the three - step steel electroslag pressure welding electrode?: If the level of 32 thread steel bar is HRB335 (original two grade steel bar), E4303 shall be used for bar welding and lap weldingGrade HRB400 (original three grade steel), bar welding, lap welding using E5003Grade HRB335 (original two grade steel), groove welding using E5003Grade HRB400 (original three grade steel), groove welding using E5503

Q:What is the corresponding brand number of electrode model E55?: Welding rod model E55 * *, its brand is J55 * *, such as J507.

Q:What kind of steel bars are used for the two electrodes?: Their strength is different, J422 is 42 kg class, J502 is 50 kg class, steel model I don't understand. J502 welding thread steel is appropriate.

Q:Requirements for welding electrodes for temperature and humidity: Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.

Q:What is the cause of partial magnetic blow?: The magnetic lines of force around the arc may be evenly distributed;2) adjust the dip angle of the welding rod properly and tilt the electrode towards the blowing direction;3) the method of subsection retreat welding and short arc welding can effectively overcome the magnetic deviation blow;4) AC welding instead of direct current welding. When alternating current welding is used, the induced current is induced by the changing magnetic field in the conductor, and the magnetic field produced by the induced current weakens the magnetic field caused by welding current, thus controlling the magnetic bias blow;5) place a ferromagnetic material that produces a symmetrical magnetic field, so that the ferromagnetic material around the arc is uniformly distributed;6) reduce the residual magnetism on the weldment. The residual magnetism on the weldment is mainly caused by the orderly arrangement of atoms and domains. In order to reduce or prevent the magnetic deviation of the magnetic domain arrangement of the weldment, the part of the residual magnetism on the weldment can be locally heated, and the heating temperature is 250~300 degrees centigrade. After production, the demagnetizing effect is good. Moreover, in the residual magnetic field of the weldment, the applied magnet balances the magnetic field.7) reverse demagnetization. That is, a magnetic field is produced by the welding piece to counteract the residual magnetism on the weldment so as to overcome and eliminate the influence of the magnetic deviation blow on the welding arc.
