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:What electrode is used on the rails?
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:J422 electrodes are marked with "THJ422". What does TH represent?
TH: Tianjin Bridge Welding Materials Group Co. Ltd. manufacturer brands. J: stands for structural steel welding rod. 42: two figures indicate that the minimum value of tensile strength of deposited metal is 42kgf/mm2 (412MPa), and the minimum value of the yield strength of deposited metal is 34kgf/mm2 (430MPa). 2: third digit "2" indicates that the type of coating is titanium calcium type, direct current or AC power supply.
Q:What is the corresponding brand number of electrode model E55?
Welding rod model E55 * *, its brand is J55 * *, such as J507.
Q:Electrode whitening what reason?
What welding rod?
Q:What is the substance on the outside of the electrode?
The electrode coating consists of various minerals, such as iron alloy, organic substance, water glass and other raw materials.Composition of electrode according to their different functions can be divided into arc stabilizing agent, fluxing agent, gas forming agent, deoxidizing agent and alloy slag agent, dilute agent and binder etc..
Q:What type of pig iron electrode?
Pig iron electrode is cast iron electrode, the vernacular is the pig iron electrode.Cast iron electrode commonly used model:CMC-E46NDirect welding on cast iron is very effective for metal wear of stamping dies. The first layer of welded metal is austenitic, and the martensite is from the 2 layer, so the wear resistance is good. Flame hardened cast iron can also be directly welded.CMC-MS64NCast iron welding rod, high strength and good plasticity. Suitable for gray cast iron and nodular cast iron, and can be machined.CMC-E47NDirect welding on cast iron is very effective for metal wear of stamping dies. The first layer of welded metal is austenitic, and the martensite is from the 2 layer, so the wear resistance is good. Flame hardened cast iron can also be directly welded.CMC-E67NEspecially suitable for cast steel hardfaced making render buffer layer, cracking of welding, welding reconstruction.CMC-E65NCmc-e65n low temperature welding, low expansion coefficient, slight hardening, especially suitable for cast iron cast steel (fc.fcd) steel hardfaced making render buffer layer.CMC-E61NSuitable for welding all kinds of cast iron, alloy cast iron, steel and cast iron joint, nickel and its alloy, or welding of water proof die castings.WE777 special cast iron welding rodSuitable for the full range of cold welding welding, welding cast iron base material can almost all, and it is easy to achieve cast iron and carbon steel dissimilar metal welding, such as solving matrix fracture, crack, wear, hole filling defects after welding can be machined, many applications in the engine casing, cylinder head, casting machine, gear base the tooth of iron castings.
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.
Q:What's the difference between 506 electrode and 502 electrode?
502 is an acid welding rod, welding process is good, but the crack resistance of welds is not as good as 506. 506 is alkaline welding rod, welding process is slightly worse, the weld is low hydrogen type, crack resistance is good. Two kinds of welding rod can be AC and DC dual-use.
Q:How to weld stainless steel electrode?
Eighty hours in advance drying 400 hours, the current fast welding
