Q:2520 what type of welding rod is used for welding?
2520 plate is stainless steel sheet, that is, we often say 310S (American brand), because of nickel (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid resistance, salt resistance, high temperature performance. The corresponding electrode number is A402 (model E310-16), and the argon arc welding line is HCr25Ni20 (model ER310)
Q:How much is the electric welder with 4 mm electrode?
Hello, if you burn it for a short time, ZX7-250 will do, 250 of the sub 220V 380V and 220 380V dual voltage. If you burn for a long time, use ZX7-300
Q:Electrode E4300 what does it mean?
It is mediocre, mediocre, obviously don't know anything in this scribble. E4300 brand is J420G, welding high pressure steam pipe is dedicated pipe, all position welding rod, deposited metal high temperature resistance, high pressure, good slag removal, less spatter, slightly higher than 422 electrode viscosity
Q:Question Q235 weldability of carbon steel. What are the welding characteristics of those electrodes?
Q235 belongs to low carbon structural steel. Better welding process. The following welding electrodes can be used:1: Brand: J422, model: E4303 titanium calcium type low carbon structural steel welding rod. (acid electrode, AC and DC).2: Brand: J426, model: E4316, low hydrogen and low carbon structural steel welding rod. (basic electrode, AC and DC).3: Brand: J427, model: E4315 low hydrogen sodium type low carbon structural steel welding rod. Basic electrode. DC reverse connection).
Q:What does "E43" and "E50" mean by welding electrodes of steel bars? What is the exact shape?
E43 series:E43, the tensile strength of the deposited metal is greater than or equal to 42MPa (430kgf/cm2) E50 series:E50 series - the tensile strength of the deposited metal is greater than or equal to 49MPa (500kgf/cm2) Specific shape: conventional drug skin, hand welding electrode.Turn left and turn right |
Q:What type of welding machine is needed for welding 3.2mm electrode?
The electrode thickness with the welding machine type does not have what relation, mainly with the welding of the welding current on the size of the 3.2 electrode electrical machine above the amount of output current of 200A welding machine, 160A welding of thin sheet metal, can also be slightly bigger, the thickness is not.
Q:Difference between ordinary electrode and tungsten electrode
The common electrode: in the welding process, it is also the weld metal fill electrode, its edge welding edge melting, and to fill in the weld.Tungsten electrodes: non melting electrodes for manual argon arc welding. Or plasma melting non melting electrodes.
Q:What welding rod should be used for welding between No. 20 and No. 45 steel?
No. 20 steel and No. 45 steel belong to dissimilar metal welding. Recommended electrode: J506 or J507.Steel No. 20 belongs to low carbon structural steel. It can be made of low alloy structural steel electrode with J422, J426, J427 and other grade strength.No. 45 belongs to medium carbon steel. The strength level of the matched electrode is J555 J556.Can use J50 series grade intensity of basic electrode welding rod, the electrode is lower than 45 steel J55 welding rod one level, higher than 20 steel J42 welding rod one level.Recommendation: J506 (E5016) low hydrogen potassium alloy structural steel welding rod;Or: J507 (E5015) low hydrogen sodium type low alloy structural steel welding rod
Q:Shelf life of stainless steel electrode
Save good words is two years, do not damp, and if it is relatively high requirements, the use of baking, remove moisture.
Q:What type of welding rod is used for welding 16MnD?
Using J507RH welding rod.DC reverse connection.Preheat about 100 degrees before welding.When the plate thickness is less than or equal to 20mm, the V type groove is opened and the U groove is used when the plate thickness is greater than 20mm.Current: Phi 3,2 welding rod A=130-150, Phi 4 electrode A=180-200, Phi 5 electrode A=230-250.Conditional, should be done after welding stress treatment.
