Q:What is the difference between an electric welding machine and a butt welding machine?

Electric welding machine is used in the two side of relatively high pressure (more than 60V) and large current to the electrode as welding materials arc welding; while the welder is used in two times of low voltage and large current (10V) with 2 pieces of metal on the electric arc welding or from the upper and lower welding head 2 pieces of iron with high current through the self pressure contact welding.

Q:Are you selling or renting?. Is this butt welder?... Can you butt 25MM's reinforcement?

As far as I know, welding machines are all two FireWire, and three items have not been heard yet.... I make wall screws

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:CNC butt welding machine, welding is not solid, no sparks, but check the power supply voltage and wiring are all right

1: small welding current.2: the welding time is too short.3: the top forging pressure is not enough.

Q:KW how many UN1-100 pairs of welding machines?

UN1-100 type butt welding machine is about 30KW.Specific parameters are as follows:The project | machine model UN1-125ARated capacity (KVA) 125Primary voltage (V) 380Primary no-load voltage (V) 4.06-8.04Maximum welding diameter (mm) 32Rated load duration (%) 20Maximum tension (kg/mm2) 50Number of welds per hour (times /h) 20-30

Q:The structure and working principle of each component inside the best can talk about, I am 22, only contact with the industry, only to learn more to ask, at present only mastered the knowledge of physics in high school, so I do not understand too deep. Thank you!I graduated from University, and now with the construction machinery sold at home, but just beginning to contact this line, a little fuzzy. On the first floor, what you are talking about is not a machine! I know it's called flash butt welding machine. For example, 100150... There are two things that produce a breakdown current. When they are short circuited, it seems that an arc is produced, and then the iron is melted. Do you understand? Don't be so complicated. I just want to make sure every component is clear. I don't repair the machine

UN butt welding machine is a series of resistance welding machines! The normal output no-load voltage is 3-8V, which is the working principle of high current generated by low voltage, welding the reinforcement! The welding machine often appears the breakdown is the contact is not good, but the welding is not firm. You can sell it with our universal butt welder in Shanghai, all copper! The failure rate is very low!

Q:What kind of reinforcement is needed for 32MM steel bars on Railway overpasses, what kind of welding machine is preferred for welding machines, what brand is selected and what type?. Please help users answer, thank you very much

1 、 using UN2-150 welder.2 、 flash butt welding is widely used for longitudinal connection of steel bars and welding of prestressed steel bars and screw end rods. The principle is the use of flash butt welding of reinforcing steel welding ends make contact through the high current low voltage, the steel is heated to a certain temperature to soften the axial pressure on the formation of forging, welding head. Flash butt welding of reinforcing steel, continuous flash welding, preheating flash welding and flash preheating flash welding. The fourth grade steel bar is sometimes treated with electric heating after welding.3, steel (Rebar) refers to reinforced concrete and prestressed reinforced concrete steel, its cross section is round, sometimes with rounded square. Including round steel bar, ribbed steel bar and twisted steel bar. Steel bars for concrete reinforcement is straight or strip steel plate reinforced concrete reinforcement steel, its shape is divided into round steel bar and deformed steel two, straight and coiled state for delivery two.

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:Construction steel butt welding or welding good?

First of all, consider the construction of steel products to be welded quantity and strength requirements.The butt welding belongs to pressure welding and is suitable for mass production in batches.Electric welding is melting welding, its operation is flexible, suitable for field welding, and the two welding methods are different in use, so they can not be replaced by each other.From the performance of the joint, the welded joint is well welded, so the quality of welding is higher than that of the welding.

Q:Technical parameters of butt welding machine

Electric welding machine technical parameters of you, is the actual design of a welding transformer, the transformer design is a very complex process, but, if you want a homemade welding transformer, can be a simple formula: 1, core area (core content) by welding power is selected, formula: square *0.7-1 power W; 2, block line window is determined by the winding and insulation materials occupy *1.2 sectional area; 3, the conductor cross-sectional area by the input / output current is determined by the *2-3; 4, the number of winding turns by the core area * flux (generally optional 8000-12000 Gauss) in addition to the input / output voltage input (usually from 380v/220v. The output of 50-80v).
