Q: 422 what does "electrode" mean?: J422 carbon steel welding rod profile, J422 welding rod is common name (also known as brand), corresponding to international standards, welding rod model E4303. It is a kind of acid electrode, titanium calcium coating, J structural steel electrode, the tensile strength is 42 42kg/mm - weld metal, weld metal tensile strength of not less than 420MPa.

Q: What is the difference between A302 stainless steel electrode and A402 stainless steel electrode?: One for 309SThe other one is used in 310S

Q: 304 can I use A022 welding rod?: Strictly speaking, you can not, the electrode class is too high, A022 welding rod is used in 316L, and 304 should use A102

Q: J422 welding rod, 10MM steel plate.: A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.

Q: What is the J422 electrode core material: Steel wire core is general, steel wire

Q: How can I distinguish the basic electrode or the acid welding electrode from the welding rod number?What are the basic electrode models?What are the types of acid electrodes?: The number of electrodes from 0 to 6 is acidic, and 7 to 9 is alkaline

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: Please say a bit more detailed, you can weld the boiler's welding rod varieties, models are said...: 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: What does "E43" and "E50" mean by welding electrodes of steel bars? What is the exact shape?: Minimum tensile strength of E43xx deposited metal 430MPa;Minimum tensile strength of E50xx deposited metal 500MPa.
