Q:How to calculate power for butt welding machine
The most conservative approach: welding work, clamp the power supply current: A*V is power (W), if it is three-phase welding machine, then *1.4.
Q:What kind of power supply is common for welding machines used on site?
General steel welding machine about 100KVA input power, big have 150KVA, small have 63KVA.
Q:Construction steel butt welding or welding good?
If you have to choose the resistance butt welding electrode arc welding steel bar, then resistance butt welding.However, the power consumption of resistance butt welding is great, and the rate of welding finished products is lower than that of electroslag welding. The efficiency of electrode welding is low.Vertical electroslag welding of steel bars is better. Welding machine load rate is not less than 60%,However, welding machine at least 500A, the maximum can be welded 25 mm diameter steel bar,630A can weld steel bars of 32 millimeters in diameter.Welding efficiency of welding rod is low.
Q:Will the frame beam longitudinal stress, steel E55 electrode, the power requirements of the welding machine?
Specific requirements for you to see what the problem of choosing motor electrode, are required, what do you use for electrode current and what specific requirements, the electrode that has will help you choose what what current high current motor
Q:Is the spot welding machine good or DC?
AC welding machine is the wire package step-down transformer using welding rod, this machine, old technology, power consumption, copper consumption.The DC welding machine includes thyristor, inverter (MOS tube, IGBT single tube and IGBT module), and the technology is more and more advanced.The inverter is a new technology that has appeared in the last 10 years, saving more than 35%. Because there is no large transformer, a great deal of copper is saved, and the transformer consumption is also reduced a lot. The disadvantage of DC is that the magnetic deviation blows, and the other is all advantages. Arc stability, weld formation is good, and there is welding rod, general acid welding rod is AC and DC can use, alkaline welding rod recommend DC, cellulose electrode, seems to only dc.
Q:Who can tell how many volts are needed for the two welding voltage of the welding machine. The weldment is wall thickness 1.5mm diameter 21mm round tube T type butt joint. How many ampere current is needed?
Two no-load voltage, ranging from 4-12V. The power is large and the load is high. In general, 5-10A current per square millimeter is required.
Q:Fixture for flash butt welding? Advantages and disadvantages of semi-automatic flash butt welding machine and automatic
Semi automatic butt welding machine has high working efficiency! Reliable welding quality! Long service life! The labor intensity of the workers is low! Easy management! Ten hours of manual welding, the 300 joints are out of order. Semi automatic, easy to weld 700-800. Automatic welding is of the best quality. But now based on the production level and components of poor stability, work conditions and other reasons, the failure rate is higher. If you have a large amount of welding, I suggest you choose semi automatic butt welder.UN2 series semi automatic welding machine is the Hebei province Zhuozhou City Pine shop Welder Factory (03123952090) for reinforced butt welding meet the construction requirements of the industry in the UN17-150 automatic welding machine and UN series of manual welding machine based on the new development of improved energy-saving products.UN2 series semi automatic welding machine by UN17-150 automatic welder of aerodynamic clamping and pneumatic forging principle, and uses the UN series of manual welder manual feeding, preheating burnt structure, with electrification control action program and parameters in the welding process. When welding, the end contact heating is adopted, and pneumatic welding, manual preheating, manual flash and automatic upsetting are used for welding. Rated capacity of 150KVA and 200KVA. Suitable for welding low carbon steel, medium carbon steel and high speed steel strip, rods and tubes and other components, welding steel bar diameter with 14- with 40mm. When welding, depending on the size and shape of the workpiece, resistance welding or preheating flash welding can be used. The key parts of the whole machine, such as solenoid valve, cylinder and SCR, are imported or domestic factory parts. The name of the main transformer factory, silicon steel and copper, high insulation, good heat dissipation effect can work for a long time.
Q:For welding with steel wire, what method do not let it break
Do you weld low carbon steel?And the principle of equal strength used in welding rod and weldment, or the principle of equal composition?Try the ingredients principle!After the welding is finished, after annealing, you try
Q:What is the reason that the welding band saw blade is not firmly used after two years of flash butt welding machine? How to solve?
It is suggested that the new jaw be replaced and the two maintenance of transformer shall be carried out. Our company will do the maintenance and maintenance of old machines for the major steel wire rope and steel cord industry all year round
Q:UN1-125 type butt welding machine working principle, who knows, I encountered the problem is welding power, but can not work, who can give I I answer?
Now domestic welding machine number is quite confusing. First of all, would you like to tell me whether it's pneumatic or manual?. Separately, it is simply that the machine uses no compressed air as the source of air.Then, the problem you describe is relatively simple, and the welder doesn't work on power. What you mean by "electrify" means that the control box has electricity or other display power is on. Or is there a connection between the two electrodes, and there is no electricity through the work room? You can explain it in detail so that I can explain it to you.
Our factory has a senior technical team engaged in plastic pipe welding equipment research and design. The guideline of our enterprise is "user's need is our pursuit; the product quality is the lifeline of our enterprise". Our aim is to be a world-famous factory. Our products include TGH multi-angle welding machines, DQJ multi-angle cutting machines and RDH hot-melt welding machines.
