Q:How to select welding rod for welding Q245R Q345R?
In the choice, should pay attention to the following points: Q245R and Q345R manual welding can use E5015 J507 welding rod, embedded welding H08MnA welding wire. Carbon wire and low alloy steel welding wire are adopted by welding wire model ER50-6, standard GB/T8110-2008 gas shielded arc welding.
Q:What kind of welding rod used for cast steel?
Cast steel can be divided according to the composition of low carbon steel, medium carbon steel, different components of the electrodes used is not the same, if it is a low carbon composition, the common electrode, such as E4303 (J422) on it; if it is steel components, should be used in high strength structural steel electrode, such as E5015 (J507) E5515 (J557), welding welding and preheating, to prevent cracks.
Q:Why not use 422 electrodes and 502 electrodes on the site? (Shanghai Kunming Railway)
422 is common steel electrode, 502 is manganese steel welding rod. They have different welding materials. The simple point is that if the 422 manganese steel is used, the weld seam will crack and will not be welded.
Q:What does E4315 mean on the electrode?
E stands for "43" electrode, the tensile strength of the minimum value, "1" means 0 and 1 indicate the position of welding, suitable for all position welding, suitable for welding and 2 horizontal fillet welding, 4 for vertical down welding, welding current "5" type and type of coating.In fact, J427 low hydrogen electrode
Q:Please say a bit more detailed, you can weld the boiler's welding rod varieties, models are said...
Welding furnace electrode is the most commonly used J422 and J507 two.Because often used in boiler manufacture, commonly used steel is: sheet --Q245R (20g) and Q345R (16Mng)Profiles --20# (GB3087) tubing 20# (GB699)Among them, the electrode matching Q345R (16Mng) is J507, and the other three kinds of materials match with J422 electrode.
Q:How much is one kilogram for common electrode?
Huajin welding materials group has so electrodes and are wholesale price
Q:What are the characteristics of welding rod E6010? What are the main points of operation?
E6010 type welding rod belongs to all position welding rod of cellulose, which has great arc blowing force. When using, direct current welding machine and reverse polarity welding method are adopted, the lower welding is fast, and the welding speed is faster.
Q:T107 purple copper electrode welding with what
The arc welding of AC welding machine is unstable using inverter direct current welder.Instrument introductionInverter DC welderInverter direct current welding machine is a kind of high-efficiency energy-saving welding machine developed on the basis of absorbing the same advanced technology internationally. The inverter direct current welding machine adopts imported famous brand IGBT module and advanced inverter technology. It has fast dynamic response, easy arc starting, stable current, small welding spatter and beautiful weld formation. It has the functions of preset current presetting, arc striking current and thrust current adjustment, so that welding operation is easier. The automatic compensation of the power network and the protection function of over current, over voltage, under voltage and over heating make the welder more safe and reliable.Inverter direct current welding machine is a kind of high-efficiency energy-saving welding machine developed on the basis of absorbing the same advanced technology internationally.

Q:400A DC inverter welding machine, suitable for long welding electrode
Diameter 4 electrode.Inverter welding machine load rate is generally 60%, 60%, load rate of about 250 or above. Electrode selection current formula is the diameter of the welding rod x (33-55) times = welding current.220 the maximum electrode current is about 4. Current output of welding machine.
Q:What kind of material is the drill pipe and what kind of electrode?
Oil drilling pipe performs API 5DP standardCommonly used steel grade S135, G105, X95, E75. The usual specifications are 60.373, 88.9, 101.6, 114.3127 and so onIt is suggested to use Baosteel brand petroleum drill pipe
