- Q: How are the electrodes made up?
- Answer: welding rod is coated with the skin of the power supply arc welding melting electrode. It is composed of two parts covering and core wire. (L) cores. 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 energy; two welding core melting filler fused with the parent metal weld formation. The special steel wire used for welding can be divided into three categories: carbon structural steel, steel wire, alloy structural steel wire and stainless steel wire. (2) medicine skin. The pressure on the surface of electrode coating called coating. A coating of various minerals, such as minerals, is coated on the outside of the electrode to stabilize the arc and improve the quality of the weld. Some reducing agents should be added into the coating to restore the oxide to ensure the quality of the weld. Because of the high temperature of the arc, some of the alloying elements contained in the weld metal are burned (oxidized or nitrided), which reduces the mechanical properties of the weld. By adding ferrous alloy or pure alloy element to the electrode coating, it can be transferred to the weld metal with the melting of the coating, so as to compensate for the burning of the alloy elements and to improve the mechanical properties of the weld metal. It can improve the welding process performance, make the arc stable combustion, less spatter, good weld formation, easy slag removal and high deposition efficiency. In short, the role of the drug skin is to ensure that the weld metal to obtain the required chemical composition and mechanical properties, and make the welding rod has good welding process performance.
- Q: Where to buy electrodes, how to buy online, welding rod is always not assured
- If the special electrode used for maintenance, the use of special technology, and Wiodin (Tianjin) Welding Technology Co., Ltd. get in touch
- Q: What wire and electrode are used for the welding of 0Cr18Ni10Ti stainless steel pipes? Thank you
- With corresponding 347 electrode and welding wire
- Q: Does the welding rod have a shelf life?
- Must have ah, Pro is generally two or three years, but save the good words, do not let him wet, you can put many years of welding rod, afraid of moisture, and what problems can ask me again
- Q: Is there any difference between welding wire and welding rod? What is the production process of welding wire? What kind of equipment do you need?
- Rod and wire are welding materials, before only electrode, later with the development of science, some of the drawbacks of the electrode show out, such as weld joints more slow, wire appear to make up for some of the drawbacks of the electrode, but now there are some electrode to his advantage, but the annual output has been wire phagocytosis, especially the flux cored wire is the main direction of future development.As for the production process, first of all, the raw material processing, peeling, phosphating, through the mold drawing, pickling, washing, copper plating, polishing, etc..
- Q: 304 generally use A102 welding rod,321 generally use A132 welding rod,Dissimilar steel A302 welding rod,May I ask if 304 can use A132 welding rod? Why?
- 1, no, in addition to welding and to achieve the parent material and other strong mother, but sometimes need to consider the toughness of the weld zone, with high strength instead of reducing the performance of materials.2, A132 is a kind of Cr19Ni10Nb stainless steel welding rod containing Nb stabilizer. It has excellent intergranular corrosion resistance and good mechanical properties. With excellent welding process and anti porosity property, drug Pinai redness, anti cracking, but the ac-dc.3, 304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry. 304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.
- Q: Why do welding electrodes need heating?
- Prevent welding rod from wettingPreheat the cores, enhance electrode weldabilityIt's also a welding processThe electrode (covered electrode) welding or welding filler metal in melting joint welding of the workpiece.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: What brand of carbon steel electrode is the best?
- For welding rod:Domestic brands, then, the best in the Atlantic, where the CHE58-1 is simply a classic product.Foreign brands, then, Lincoln, Esab and so on are also classic brands, Olin Kang is the best.
- Q: When welding, the welding rod sometimes can easily stick to the weldment, and it is not easy to arc. The ignition is also easy to extinguish. Why is that? What happens when this happens?
- 1, welding current is too small.Please refer to the instruction of welding current in electrode box, choose the suitable welding current according to the welding position.2 basic electrode welding with AC welder.J426, J506 and other low hydrogen potassium welding electrodes must be welded with BX series alternating current welding machine with no-load voltage above 70V. The lower the no-load voltage of the welder, the easier it is to stick the welding rod.3, the welding rod model is wrong.J427, J507 and other low hydrogen sodium welding rod, unlike low hydrogen potassium electrode containing arc stabilizer, the welding rod must be welded by DC welding machine. AC welding machine will stick welding rod, cannot arc.4, improper operation. Basic electrode (low hydrogen potassium welding rod, low hydrogen sodium welding rod, etc.) shall adopt the method of striking and striking arc. Just as a match, the end of the welding rod and the construction of contact, a slight rub can ignite the welding arc. If the direct striking method is used, the welding rod is unavoidable.5, technical problems. The arc welding rod should lift the arc 1-3 millimeters rapidly and enter the normal welding mode. Otherwise, long time welding rod and workpiece short-circuit will dip electrode.
- Q: What type of welding rod is applied to Q345 steel plate?
- E50 series (E5001~E5048) welding rod can be. To adapt to the requirements and welding of steel used in SMAW electrode, using the intensity principle of E50 series E55 series above right above strength, high cost, comprehensive strength and economic aspects, should choose E50 series of electrode.
