- Q:What kind of welding rod is used for No. 55 steel?
- No. 55 steel belongs to medium carbon steel and its weldability is poor. It should be preheated before welding. General structure arc welding using E4301, E4303, E4311, E4313, E4320 or J422 welding rod can be. The stress (main body) structure arc welding uses E4315, E4316, E5015, E5016 or J425 welding rod.
- Q:2.5, 3.2, 4, 1 kilograms of welding wire, how many branches?
- 2.5 a pack, 4.5 kilograms, 230 or so
- Q:What enterprises use more welding electrodes?
- A lot of chemical factory is that kind of production of high pressure boiler, non-standard tanks, cans and so on
- 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.
- Q:How long is the effective period of welding rod?
- If the stock period exceeds the prescribed time limit, the electrode, flux and flux cored wire must be re examined before the relevant functional departments can be issued and used. complexTest principle to check whether the welding material may affect the quality defects, generally limited to appearance and process performance test, but there are doubts on the performance of welding materials, can increase the necessary inspection item.The prescribed time limit may be determined by the following method from the date of production:A) the period of recommendation for welding materials, quality certificates or manuals;B) a low hydrogen type welding material for acid welding materials and moisture resistant packages, sealed for two years;C) graphite type welding materials and other welding materials for one year.
- 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 can't manual arc welding be performed with bare electrode?
- The crust is intended to weld the pool over the metal, forming a skin to protect the molten pool from contact with air. If there is no medicine, the skin will protect the blowhole.
- Q:Method for using welding rod heat preservation barrel
- Put in the electrode and plug into the power supply,Reach a certain time
- Q:2.5 what is the current of the welding rod sheet?
- Welding sheet iron generally use 43 kg class acid electrode J422, current in 80-100A, welding thin sheet iron current should not be too small, the current is too small, but easy to weld through.
- Q:What kind of material is the drill pipe and what kind of electrode?
- Oil drill pipe is a high carbon steel material, using WEWELDING 600 welding.Selection of electrodes of 3.2 mm diameter welding current, in 100-120A, the cold welding welding process can be.Application of WEWELDING600 special alloy steel welding rodSuitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.Technical parameters of WEWELDING600 special alloy steel welding rodTensile strength: 125000 psi (862MPa)Yield strength: 90000 psi (620MPa)Elongation: 35%Hardness after welding: HRC23 (work hardening up to HRC47)Power supply: AC and DC dual use, DC DC reverse connectionProcess parameters of WEWELDING600 special alloy steel electrodeDiameter (mm) Phi 2.5 Phi 3.2 Phi 4Current (Amperes) 40-80, 65-120, 90-150Packing weight (LBS) 222Applicable technology of WEWELDING600 special alloy steel welding rod1, WEWELDING 600 alloy steel electrode (referred to as WE600 or Wiodin 600 electrode) has very favorable thermal expansion and cold shrinkage, can make cracks and distortion minimum.2, it is an ideal choice to lower the weld seam when welding the metal which is sensitive to the crack.3, with thick parts, forming a 90 degree V groove.4, welding high carbon steel before preheating 200 degrees; welding spring steel to control the welding temperature, in case the spring softening.5. Maintain a short arc length and use a narrow bead to prevent overheating.6, before removing slag, let the welding site cooling.
