Q: 422 what does "electrode" mean?: 422 electrode is commonly called, corresponding to international standard brand E4303. It is a kind of acid welding rod, the coating is made of titanium and calcium, and J stands for structural steel welding rod. 42 is the tensile strength of 42kg/mm2 weld metal. The tensile strength of molten steel is not less than 420MPa, and the yield point is greater than 330MPa.Main application: used for welding low carbon steel structures with low strength and low strength. They are generally used for welding steel structures and welding of ordinary carbon steel pipes.My answer hopes to help you! Please click on the adoption bar! Thanks!

Q: What's the difference between 507 and 422 electrodes?: The main difference is the intensity, a difference; another 507 are low hydrogen alkaline electrode, DC reverse; 422 is an acid welding rod, AC and DC dual-use

Q: Is it used for welding power plant construction?: Base metal is 10, 20 steel with J427Stainless steel with A102

Q: Welding specification whether welding rod needs experiment: Enterprises need: welding rod, welding flux, welding wire must be dry, heat preservation treatment, and need to do some process evaluation, can determine whether the welding rod suitable for such welding, process evaluation is more important.

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: Drawings require E43 electrodes, the market says 422 of the electrode, the package is written on the CFE422! Q235B seamless steel pipe should be welded. Can you tell me what kind of electrode should be used then?: You buy the electrode is right, you say E43 is GB model, 422 is the manufacturer's brand, you can weld Q235B steel pipe.

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.

Q: Why can DC welding machine weld any electrode?: Direct current, especially the direct current produced by the inverter DC welding machine, is relative to the power frequency AC welding machine. The arc is stable, the spatter is very small, and the arc is not easy to break. The welding parameters have almost no fluctuation under the influence of input voltage. Three phase welding machine also supports thrust current, hot arc ignition function. It can avoid sticking electrode when arc welding with basic electrode. If there is no frequency exchange of AC, it is difficult to weld slag hole. A metal with a high sensitivity to carbon is not susceptible to cracks in heat sensitive metals.Basic electrode J426 J506 can be AC DC welder dual-use. These two kinds of welding rod contain arc stabilizer. However, from the quality of welding, DC welding machine is much better quality than AC welder.

Q: What kind of welding rod is used for No. 55 steel?: To choose J506 or J507 welding rod, preheat 150~200 degrees before welding, heat preservation after welding. Or choose the electrode with higher strength grade

Q: What are the functions of E506 structural steel welding rod, which material is suitable for processing?: Compared with J507, one is low hydrogen potassium type, one is low hydrogen sodium type, and 506 because of adding arc stabilizer, it can be AC and DC dual-use.
