Q: Can A102 welding rod weld 316L?: 316L belongs to ultra low carbon austenitic stainless steel, and if using A102, weld metal will reduce the ability to resist intergranular corrosion, so in the relatively high requirements of equipment, as far as possible using A022 welding rod.

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: 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?: General electrode brand will see E308-15 or -16 or -17,Suffix 15 means that the electrode is alkaline, and the reverse polarity is welded;Suffix 16 means that the electrode can be an alkaline coating, or a titanium or a calcium titanium based coating for both hand and dc;The suffix 17 is a variant of the drug skin type 16, which means that the electrode is made of titanic acid type and can be used for both hand and DC purposes.The ingredients and operation characteristics of the rings 25 and 26 are similar to those of the electrode type 15 and 16. The specifications of the type 15 and 16 of the electrode type are also suitable for the type 25 and 26 of the coating types. According to the nature of the electrode coating, the electrode can be divided into two categories: acid electrode and basic electrode.Drug skin contains a large amount of acidic oxide (TiO2, SiO2, etc.) electrode, known as the "acid electrode.".The skin contains many basic oxides (CaO, Na2O, etc.) called alkaline electrode.Acid electrode can AC-DC, the welding process performance is better, but the weld mechanical properties, especially the impact toughness is poor, suitable for welding low alloy steel for low carbon steel and low strength, is the most widely used electrode.The basic electrode has strong desulfurization and dephosphorization ability, and the coating has the function of hydrogen removal. The hydrogen content of welding joint is very low, so it is also called low hydrogen type welding rod. Basic welding seam has good crack resistance and mechanical properties, but poor technology performance, general DC power supply welding, mainly used for important structures (such as boiler, pressure vessel and alloy steel welding etc.).

Q: Why do I use J422 electrode iron rail welding after their split seam. Later, the use of 506 electrodes did not have such a situation, I would like to ask what the rail contains? Yes. Is my J422 electrode fake? And... Is it my technique? Maybe the rails contain special ingredients? The person who knows it will answer immediately, "why does the seam split itself?": J422 is a titanium calcium type coating, acid electrode, tensile strength is more than 420MPa; the mechanical properties of rail, which is an indicator of tensile strength, mechanical properties of the rail are as follows:Steel tensile strength /MPa elongation / rail tread hardness% center line (HB)U71Mn, UIC900A = 880, 260~300 = 10PD3, BNbRE = 980, 280~320 = 9EN260 = 880 = 10 260~300 seen from the rail, the tensile strength is more than 880MPa, but the J422 tensile strength is more than 420MPa, so they will split the weld. J506 electrode for low hydrogen potassium type coating is added on the basis of the J507 formula in the arc stabilizing agent amount, the main welding electrode equivalent strength steel, low-alloy steel, ship steel and pressure vessels, such as 16Mn, 09Mn2Si etc.. Belong to the high manganese steel electrode, is the implementation of the "national standard" GB98485 surfacing electrode, electrode, the work hardening is particularly high, which improves the Mo crack resistance and wear resistance, hardened up to HB = 450-500. Higher than the rail 320, so the 506 welding rod welding rail, welding seam will not split.

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: J422 electrodes are marked with "THJ422". What does TH represent?: J422 is the brand of welding rod GB. As for the TH is the enterprise stipulated grades, the first letter T should be on behalf of the welding electrode (strip of the first letter); second letters H, should be related to the electrode trademark or manufacturer's name.
