- Q:Please tell me the current corresponding to various types of welding electrodes in detail!
- Empirical formula for welding current and electrode diameter: I=dk I--- welding current (A); d--- electrode diameter (mm); k--- empirical coefficient (30~50)Welding current of phi 2.5 electrode is 50A ~ 80AWelding current of phi 3.2 electrode is 100A ~ 130AWelding current of phi 4 electrode is 160A ~ 200AMore than 4 of the diameter welding current is 200A ~ 250A
- Q:Can 50Mn2 casting be welded with 507 electrodes?
- 50Mn2 is medium carbon steel, while J507 electrode is a low carbon component. If 507 electrodes are used to weld, the carbon content of the weld seam is lower, which will reduce the joint strength. Therefore, the welding of 50Mn2 steel with J507 welding rod can not guarantee the strength of the weld seam. It only applies to the welding of the weld when the strength of the joint is not high.
- Q:How are the electrodes made up?
- Answer: welding rod is coated with the skin of the power supply arc welding melting electrode. It is composed of two parts covering and core wire. (L) cores. The electrode is metal cored coating called cores. The core is generally a certain length and diameter of the steel wire. When welding, the welding core has two functions: one is the conduction of the welding current, arc energy converted into heat energy; two welding core melting filler fused with the parent metal weld formation. The special steel wire used for welding can be divided into three categories: carbon structural steel, steel wire, alloy structural steel wire and stainless steel wire. (2) medicine skin. The pressure on the surface of electrode coating called coating. A coating of various minerals, such as minerals, is coated on the outside of the electrode to stabilize the arc and improve the quality of the weld. Some reducing agents should be added into the coating to restore the oxide to ensure the quality of the weld. Because of the high temperature of the arc, some of the alloying elements contained in the weld metal are burned (oxidized or nitrided), which reduces the mechanical properties of the weld. By adding ferrous alloy or pure alloy element to the electrode coating, it can be transferred to the weld metal with the melting of the coating, so as to compensate for the burning of the alloy elements and to improve the mechanical properties of the weld metal. It can improve the welding process performance, make the arc stable combustion, less spatter, good weld formation, easy slag removal and high deposition efficiency. In short, the role of the drug skin is to ensure that the weld metal to obtain the required chemical composition and mechanical properties, and make the welding rod has good welding process performance.
- 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:What is the difference between A507 welding rod and J507?
- The A507 electrode is austenitic stainless steel electrode, J507 is carbon steel electrode, both low hydrogen basic electrode coating, estimation of similar components, the core is not the same, one is a carbon steel, stainless steel.
- Q:What kind of welding rod is used for No. 55 steel?
- No. 55 steel is made of genuine WEWELDING 600 welding rod.Because the 55 steel for high strength steel, treated with surface hardness and high strength, plasticity and toughness but poor machinability of medium, weldability, hardenability, water quenching is the tendency for crack formation, welding crack resistance of the need for a very ideal electrode to WEWELDING 600 welding, ensure tensile strength requirements of crack resistance and use of the process after welding.Characteristics of WEWELDING 600 special alloy steel welding rodWEWELDING 600 is a low heat output, suitable for special nickel chromium alloy steel electrode welded all-round, universal design is extremely wide, the general strength of parent materials with high strength, excellent welding performance, stable arc, beautiful shape of seam, in oil, water and rust conditions can welding effect is excellent, can be welded different steel.Application of WEWELDING 600 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 WEWELDING 600 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 connection
- Q:When 507560 electrodes are used at the same time, which electrode should be selected?
- 1, J506 welding rod, J507 are basic electrode.2, J506 welding rod can be AC and DC dual-use.3, J507 welding rod can only use DC welder.4, if there is no DC welding machine should use J506, if J506 arc difficult, you can consider using J502.5, J507 welding rod crack performance is better than J506.
- Q:Can ordinary 422 electrode welding pig iron?
- Not welding, easy to fall off after welding, resulting in more defects more defects. Can use cast iron welding rod Z308, the worst to use A302.
- Q:What kind of welding rod is A137?
- A137 is austenitic stainless steel electrode, belonging to chromium nickel stainless steel electrode.Grade A- indicates austenitic stainless steel; 13- is the chemical composition code; 7- represents alkaline welding rod; DC power supply welding.It is used in the welding of more important corrosion resistant and 0Cr18Ni11Ti stainless steel containing titanium.
- Q:How can I distinguish the basic electrode or the acid welding electrode from the welding rod number?What are the basic electrode models?What are the types of acid electrodes?
- The number of electrodes from 0 to 6 is acidic, and 7 to 9 is alkaline
