- Q: Air conditioning copper pipe welding problems, how to weld well, and what electrode to use?
- Brazing with 3%-5% silver electrode. A copper pipe is inserted into the other by means of flaring or necking.
- 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: Requirements for welding electrodes for temperature and humidity
- Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.
- Q: Does the welding rod have a shelf life?
- This does not necessarily depend on your preservation of the environment and the variety of electrodes, and some electrodes have been preserved for more than ten years, the use of performance is still very good. As long as it is not damp and the skin falls off, it can continue to be used.Material shelf life is not strictly required, the pressure vessel required if more than one year, should carry on the inspection, inspection qualified can continue to use, every year to conduct a test, you can still continue to use qualified.If the welding pool conditions, welding save no moisture, no deterioration, after inspection and acceptance, can still be used.If not assured, you can downgrade to adopt. There is not willing to do more information (welding rod to continue inspection of qualified data), can also be downgraded. Other industries, did not see the relevant standards requirements.Our welding wire has been produced in Japan in 1949. The welding rod has been produced in Japan in 60s and 70s. It has been well preserved. Now the chemical field inspection and maintenance are still in use. The effect is very good and the quality is not a problem.
- Q: When welding electrode, how to move the electrode, can you point it in detail?
- You see what the welding welding or welding with transverse welding point
- 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: It's expired. What color is it? It's better to have screenshots
- I checked the relevant information about electrode idle period narrative is not found, only the storage warehouse ventilation requirements. Electrode drying. No harmful gas and corrosive medium. The temperature 10-25 degrees, humidity fifty percent. To damp. Drug skin discoloration. Core rust after drying of the electrode to assess the quality of the performance indicators meet the requirements, can be assured.From the point of view of the situation (I used to put blind, for six years), medicine skin color. There are core electrode drying after rust still use, do not feel abnormal, (of course not weld inspection index). But there have been coating stripping or drying after stripping, can not use.Cast iron electrode used before heating up to 150 degrees, heat preservation 2 hours, and then use how much, how much can be used, or else there will be a lot of pores,
- Q: Welding rod heat preservation barrel should be clamped in the welding machine
- The output terminal of welding machine (or welding machine quick socket) is suitable for welding electrode barrel.
- 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 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 |
