Q:What is the J422 electrode core material
Steel wire core is general, steel wire
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:How much current does 4 of welding rod use?
You ask more generalWelding rod arc welding barIn general, the electrode is selected according to the thickness of the workpiece and the form of assemblyAfter the electrode is selected, the current is determined according to the diameter of the welding rod2.5 electrodes generally 75~903.2 electrodes generally 110~1404 electrodes generally 160~190This is a generally flat position
Q:Why stainless steel electrode is relatively short?
The reason is that the stainless steel electrode relative to the general structure of the electrode, the resistance is relatively large, if it is too long, lead to resistance heat is too large, welding electrode to the final red too much, the performance can not be guaranteed!
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:304 can I use A022 welding rod?
Sure。 304 stainless steel, A022 stainless steel electrode.
Q:2.5, 3.2, 4, 1 kilograms of welding wire, how many branches?
4 mm welding rod, a package of 5 kilograms, how many roots?
Q:A022 what kind of material is the welding rod?
Brand A022 welding rod model is E316L-16, can weld 0Cr18Ni12Mo2Ti material (recommended according to JB/T4709)
Q:What are the functions of E506 structural steel welding rod, which material is suitable for processing?
Electrode brand: J506, model: E5016 (E506 is wrong writing). It belongs to low alloy structural steel welding rod.Welding rod brand: J506, model: E5016 belongs to the low hydrogen potassium alloy structural steel welding rod. Good crack resistance. All position welding. Polarity welding requirements: AC welder (no-load voltage is not lower than 70V, the load rate of not less than 60%, the output of the welder welding current is not less than 300 Amperes) reverse DC (ground electrode connected to the positive electrode welding -, +).For 16Mn low-alloy structural steel, 09Mn2Si welding.
Q:Why is the welding of important structure using alkaline electrode?
Alkaline is a low hydrogen electrode, which can control the hydrogen content in the weld, avoid hydrogen embrittlement and lead to structural failure. Hydrogen embrittlement is the sudden breaking of the weld force
