- Q:Why not use 422 electrodes and 502 electrodes on the site? (Shanghai Kunming Railway)
- J422 welding rod is lower than steel standard. The strength of J502 is the same as that of steel bar, which is the reason of using J502 welding rod.Different reinforcement materials, the electrode tensile strength is not the same. The strength of the steel bar must be the same as that of the steel bar. The strength of the welding rod once, the steel bar will appear the weld organization intensity is low and the crack; the welding rod strength is higher than the steel bar, the welding seam and the reinforcement will have the bigger peeling force, similarly will crack.Model: J422, brand: E4303 belongs to titanium calcium type low carbon structural steel welding rod. It is suitable for low carbon structural steel with welding tensile strength Q235.Model: J502: E5003, belongs to titanium calcium type low alloy structural steel welding rod. Low alloy structural steel suitable for welding tensile strength Q345 grade.
- Q:What enterprises use more welding electrodes?
- Shipyard, boiler plant, steel structure, locomotive, automobile, construction machineryBuilding construction; large building; exterior wall decoration.
- Q:Is it used for welding power plant construction?
- Base metal is 10, 20 steel with J427Stainless steel with A102
- Q:How to calculate the amount of electrode used in pipe welding?
- The number of welds can be multiplied by the amount of each opening. The dosage of the cut can be calculated by the quota method or the volume method. Generally, a ton of steel has an average number of electrodes.Carbon steel, stainless steel or alloy steel products are joined together with other products by welding electrodes when they are in production or construction. The seam of the welding rod between the product and the product is called the welding seam. Also called weld seam.
- Q:Don't long winded, concise, thank you!
- 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:How to keep the welding electrode well?
- 1., placed in a dedicated electrode oven, to prevent moisture, 2. categories placed, to prevent confusion of different electrodes
- Q:What is bubble welding? What's the difference between a common electrode and an ordinary one?
- Bubble welding, also called gas shielded welding, refers to the welding method of carbon dioxide or argon gas protection, without welding wire. CO2 welding efficiency is high, argon welding mainly welding aluminum, titanium, stainless steel and other materials.The difference between a common electrode and an ordinary one:General welding is generally AC welding machine, welding with electrode; bubble welding generally has SCR rectifier and inverter two, gas welding machine welding efficiency is high, using disk welding wire.
- Q:I want to buy a small inverter welder, I heard that welding machine is very light, how heavy is it? It's the kind of carry. And how much is the price?. I wonder if the welder can use an acid welding rod? When welding, is it the same as the feeling of communication? I used the DC blow, it seems a little big. It's not good at all.. There is also a big point of 315 inverter welding machine, how much is it?.
- Inverter welding machine can use acid welding rod, acid electrode: slag with acid oxide based electrode."Inversion" and "rectification" are two opposite concepts. Rectification is the process of converting alternating current into direct current, while inverter is the process of changing direct current into alternating current. The arc welding power source adopting inverter technology is called "inverter welding machine"".The working process of inverter welding and cutting equipment, is a three-phase or single-phase 50Hz AC rectifier, filter get a smoother DC inverter circuit composed of IGBT or fet the DC 15 ~ 100kHz AC, the main frequency step-down transformer, rectifier and filter to obtain stable DC output again the welding current (or again the required frequency of the inverter output AC). The control circuit of inverter welding and cutting equipment is given by the circuit and driver circuit etc., by processing the signals of voltage and current feedback loop control, realize the control technology, using pulse width modulation PWM as the core, constant current characteristic and excellent welding process effect to obtain rapid pulse width modulation.
- Q:What type of welding rod is needed for the construction of three grade steel bars used in construction?
- Go to the specifications, and the material list has a given name, such as 1499.2-2007
- Q:Is there any difference between E308 welding rod and 308?
- You are not engaged in welding, this problem is puzzling. E308 is the electrode type, that is, corresponding to the domestic A102 stainless steel electrode brand. 308, a single number, what does not mean ah, including E308, R308, A308, and so on, who knows what you mean?
