Description of the working principle of flash butt welding machine-Xinxing Welding
Release time:2022.01.13
Summary of information:
There are many flash butt welding machines on the Internet that explain the principle of the flash butt welding machine relatively simply. The editor of Xinxing Welding specially wrote a detailed version so that everyone can have an intuitive feeling. I hope you like it.
Flash butt welding machineThe basic principle is the same as resistance welding, which uses the resistance heat generated when current passes through the workpiece to heat the weldment, and then upsets (extrudes) it to achieve the purpose of welding. When a current passes between two workpieces, due to the large resistance between the contact points of the two workpieces, the end surface is rapidly heated due to the electrothermal effect. The contact surface between the two workpieces is microscopically uneven, so the first contact is some protruding points. These contact points are instantly heated to a molten state after being energized, thus forming multiple liquid metal lintels between the workpiece contact surfaces. These lintels are "exploded" and destroyed during the further heating process, causing the molten metal to fly out from the gaps in the workpiece contact surfaces, forming a flash. At the same time, the workpiece is further heated. The workpiece passes throughWith the action of continuous heating and continuous flash, the temperature of the end face of the workpiece gradually becomes uniform, forming a thin layer of molten metal.layer to prevent the intrusion of surrounding gases. At the same time, the upsetting force is quickly applied to force the welding surfaces to squeeze each other, so that the fire mouth formed during the flash is fully closed, and all the liquid metal is squeezed out, and the two workpieces are welded into one.
Wuxi Xinxing Welding Equipment Factory was founded in 1993 and has been a manufacturer of resistance welding machines for 28 years. Its products include: spot welding machines, AC spot welding machines, DC spot welding machines, secondary rectifier spot welding machines,Medium frequency spot welding machine, automatic spot welding machine, energy storage spot welding machine, butt welding machine, steel bar butt welding machine, steel pipe automatic butt welding machine, flange flash butt welding machine, aluminum alloy hydraulic butt welding machine, fully automatic butt welding machine, row welding machine (multi-head mesh welding machine), multi-strand wire welding machine, cage bone welding machine, special customized butt spot welding machine, etc., more than 300 kinds, with excellent quality, favorable price, many videos, welcome to consult and purchase!

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
