Q:Flash butt welding fixture? What are the advantages and disadvantages of semi-automatic flash butt welding machine and automatic flash butt welding machine? Do you have anyone who knows? Baidu half a day without fruit ah!!

Yes, I've heard nothing about it

Q:Figure U type workpiece, rings and the straight rod are made of cold drawn wire diameter 5.3! U ring and straight link is manual arc welding, now I have modified a pair of welding machine, the welding jig is two cylinder clamping! The welding power with the power of DN-10 type electric welding machine, the problems encountered are: butt straight rod contact type U ring almost melted, can contact U ring without signs of heating, fixture and release it, just fake welding, no nugget, touch off! Before the professional steel butt welder also tried the same problem, at first thought it was wrong to fixture, but after the good fixture, or the same problem, please master pointing, in the end is what causes the U ring is not heated, thank you!

One less push action.

Q:Do welding electrodes need to be used for the welding machine? Will there be smoke and dust in the welding process?

The welding machine does not need to use the welding rod, and the welding machine uses the welding flux as the common arc welding machine. In fact, it is a big welding rod. The soldering flux is added around the butt joint material, and there will be smoke and dust in the welding process.

Q:Consult 1 sets of 100KVA butt welding machines. What is the power? How much is the power consumption per hour?

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: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:How large can the saw welder be soldered?

The welding machine can generally weld 10*0.45mm to 150*1.25., which should also consider the power of welding machine. I use the factory are high-power, widest, weldable 150mm width, the thickness of the most thick, welded 1.25, and then a bit thick can also be welded.

Q:Senior fellow: for different grades of steel requirements with what electrode problems, I have learned. What I want to know now is whether there is any requirement for the power of the welding machine with different welding electrodes If there is, then this requirement is clear on the specification, or the actual operation of direct existence? If not, is that possible as long as the DC welder is available? For example, the site construction operation radius of 53m, then we have to choose more than 55m and tower type. Troublesome seniors!

E43 * * type is used for the connection between grade HPB235 steel bars and grade HPB235 and grade HRB335 steel bars.E50 * * type is used for the connection between grade HRB335 steel bars and grade HRB335 and grade HRB400 steel bars.E55 * * type is used for HRB400 grade steel barsThe reinforced material should be consistent with existing national standards, "the reinforcement of concrete hot rolled round bar" GB13013, "the reinforcement of concrete hot rolled ribbed bar" the provisions of GB1499, welding connection reinforced in the formal welding must according to the construction conditions of welding, welding process and quality according to the current standard of "national specification for welding and acceptance" JGJ182003 execution. Cold rolled ribbed steel bars are forbidden to be welded. All steels and bars shall be certified by the factory or qualified reports, and shall be checked and accepted according to the relevant national standards.

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:What's the biggest difference between domestic and imported steel cord welder? Besides price?

Domestic imports do not have to import
