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

Welding machines work by electricity. The name literally means of welding machine is too deep for you to check the information!

Q:When the wiring of the motor is connected, how many transformers can be used for the welding machine, and the AC output of the transformer is also changed into direct current?

300W power is enough, I use the output of 35V is connected with a battery element on the line, and the voltage is adjustable easily.

Q:With steel wire welding, after welding, gently Wei, solder joint fractureReply immediately when you knowSpecific how to heat preservation, can say detailed point?

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: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

If you are alone here to ask you what is a principle, the wizards. Personal view: you don't have to make the construction and work of each component clear, because even the producer can't do it. In fact, you might as well work hard at the operation, or do some work in the maintenance or in the welding equipment. This may lead to more.

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

Continuous flash welded barsMaximum diameter (mm)10~1212~1616~2020~25Preheat Flash Welded reinforcementMaximum diameter (mm)20~2232~36FortyType of welderUN1-50UN1-75UN1-100UN2-150 welding machine model determined the largest!!!The brand does not need to ask this question, the price is different, the brand is certainly different, the principle is same with the purchase electrical appliance!!

Q:How many coarse copper core cables should be used for the butt welding machine for 100kW?

The temporary load rate of the welding machine is very short, although the power is short and the power is large, the current is:I = P/U = 100/0.38 = 263 (A)Because of its load rate of less than 10%, the transient overload of the wire will not be a problem, the experience data from the 16 square copper core wire can be loaded (in experience).

Q:What is the use of electroslag pressure welding machines, alternating current welding machines and flash butt welding machines?

Electroslag pressure welding machine: used in a column, used for vertical columns, extending from the bottom of the upward welding machine, 14-40MM, diameter 2, 3 barsAC welder may be arc welder, right?! The most common welding machine, what the overlap is basically the welderFlash butt welding machine: used in beams and boards, horizontal direction, so that it can save material, if it is overlap, then will use a lot of steel, suitable for the diameter of 10-40MM 1-3 and 10-25MM 4 grade steel bar

Q:How to choose welding leakage current

First calculate what your total power is, then select the leakage switch according to the power.The power / voltage is equal to the current. For example, the total power 4KW, then 4000/220=18A.The rated current of the leakage switch is greater than the load current.In general, the total leakage switch is selected by 1.5 times the load current, 18A*1.5=27A.There is no leakage switch for 27A, soThe leakage switch should select 32A.The leakage current is selected by 30MA.

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).

Q:What is the approximate power of the UN1-75 flash butt welder?

75 refers to the power, multiplied by 1000, power that is 75000 watts
