What should be the protruding length of the workpiece when using the flash butt welding machine?
Release time:2022.01.20
Summary of information:
Resistance butt welding, pneumatic butt welding, automatic butt welding, medium frequency butt welding, and flash butt welding all have the problem of workpiece protrusion length. Different materials have different values. Today, let’s take a look at the workpiece protrusion length in flash butt welding machines with the editor of Xinxing Welding.
Extended length: refers to the length of the workpiece extended from the electrode jaws before welding.
inFlash butt welding machineDuring operation, the selection of the protruding length of the workpiece should increase with the increase of the workpiece grade and the diameter of the workpiece. The length should also be adjusted according to the type of each metal. The longer the protrusion, the greater the impedance and the greater the power required. Generally speaking, the protrusion length of rods and thick-walled pipes = 0.7~1 times the diameter, while the protrusion length of thin plates is 1-4mm. In order to be more stable during upsetting, 4-5 times the length is generally left.
If it is butt welding of different metals, in order to make the temperature distribution on the two workpieces consistent, the metal with poor electrical and thermal conductivity usually has a shorter protrusion, and conversely, the metal with good electrical and thermal conductivity has a longer protrusion.
So what is the best protrusion length for butt welding of different metals? Please see the picture below

DBZ medium frequency resistance spot welding machine
Xinxing medium frequency inverter pneumatic resistance spot welding machine is a three-phase alternating current that is rectified into DC, and then through an inverter circuit composed of IGBT power devices, it is converted into an intermediate frequency 1000-4000HZ AC square wave output. After being stepped down by a transformer, it is rectified into DC and supplied to the electrode for welding the workpiece. Current feedback and pulse width modulation (PWM) are used to obtain stable current output. It is one of the cutting-edge resistance welding methods today. The medium-frequency resistance spot welding machine can be used for spot welding and multi-point projection welding of ordinary low carbon steel plates, stainless steel plates, galvanized sheets, aluminum plates and wires. It can also be used for spot welding and nut projection welding of high-strength steel and hot-formed steel in the automobile manufacturing industry, as well as resistance brazing and spot welding of copper wires in the high and low voltage electrical industry, brazing of silver points and copper plates, composite silver point welding, etc. Please read below for advantages and features
