What preparations should be made for the workpiece before using the multifunctional butt welding machine?
Release time:2022.05.09
Summary of information:
Before using the multi-function butt welding machine, you must first keep the welding end faces of the two workpieces at least 3-5mm identical in shape and size to ensure consistent heating and plastic deformation of the workpieces.
UseMultifunctional butt welding machineBefore welding, we must first keep the welding end faces of the two workpieces at least 3-5mm identical in shape and size to ensure consistent heating and plastic deformation of the workpieces.
2. The end face of the workpiece and the surface in contact with the fixture must be strictly cleaned. Oxides and stains on the end surface will directly affect the quality of the joint. Oxides and stains on the surface of the workpiece in contact with the fixture will increase the resistance at the contact, cause surface burns on the workpiece, aggravate jaw wear, and increase power loss.
3. To clean the workpiece, you can use mechanical means such as sandpaper, polisher, wire brush, or pickling.
4. Oxide inclusions are easy to occur in manual butt welding joints. For metals with high welding quality requirements, flash butt welding machines should be used.
5. Workpiece protrusion length preparation: that is, the length of the workpiece protruding from the electrode end surface of the fixture. When choosing overhang length, there are two factors to consider:
Stability of the workpiece and heat dissipation to the electrode fixture during upsetting. If the extension is too long, the workpiece will become unstable and distorted during upsetting. If the extension is too short, it will be caused byDue to the enhanced heat dissipation to the jaws, the workpiece is cooled too quickly, which will increase the difficulty of plastic deformation. The protruding length of the workpiece is generally calculated as a multiple of the diameter of the workpiece. The commonly used formula is low carbon steel: lo=(0. 5-1)d, aluminum and brass: lo=(1-2)d, copper: 1o= (1.5-2. 5)d.

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.

Is the flash of automatic iron pipe flash butt welding machine dangerous?
Summary of information:
Automatic iron pipe flash butt welding machine is most often used to butt square pipes, round pipes, and stainless steel pipes in furniture manufacturing, pipeline engineering, boiler manufacturing, and petroleum equipment production. Its advantage lies in flash. If the pipe port is uneven or has burrs, uneven spots, rust, oxides, etc., these can be flashed away during the flashing process. Flashing
The automatic iron pipe flash butt welding machine is most often used to butt square pipes, round pipes, and stainless steel pipes in furniture manufacturing, pipeline engineering, boiler manufacturing, and petroleum equipment production. Its advantage lies in flash.
If the pipe port is uneven or has burrs, uneven spots, rust, oxides, etc., these can be flashed away during the flashing process. The flashing time is generally between 1 and 2 seconds. Only this time consumes electricity. The rest are mechanical or pneumatic actions, which do not consume electricity and are very energy-saving. Moreover, the welding seam is as small as 0.1mm, the heat affected zone is small, the firmness is better, and the workpiece is beautiful.
The welding seam is small, and the natural grinding is faster, saving another labor force. As for flash hazards?
The editor often sees it, and I have to say that the front is very dangerous. If I accidentally take a video, the phone will be burned out by sparks. I donât know if you have seen it, but the automatic flash butt welding machine only needs one button to operate. The welding button is on the upper right side, and you only need to operate it on the side. Of course, if the employees work on a piece basis and it takes time to move, then a hinge-type baffle can be made and hung in the front, and welded with the cover to prevent splashing.
Generally speaking, any equipment has advantages and disadvantages. Just like water, water can sail or capsize a boat. As long as we make good use of the advantages, we will definitely make the quality of the product better.
