What are the reasons why a fire or explosion may occur during use of a resistance welding machine?
Release time:2021.12.31
Summary of information:
The current CNC resistance welding machine has greatly suppressed spark splash, but a lot of sparks will still be generated on some special metal materials, such as galvanized sheets. In order to remove unevenness and impurities on the port and achieve smaller interface scars, the flash butt welding machine does not turn on the spark suppression function, which can easily cause fire or explosion accidents.

AndFlash butt welding machineIn order to remove the unevenness and dirt on the port and achieve smaller interface scars, the spark suppression function is not turned on, which can easily cause fire or explosion accidents.
What are the causes of fire or explosion accidents?
1）There are flammable and explosive items or gases near the work area and they are not cleaned before work. During operation, it may be ignited by flying metal sparks or hot molten liquid, or there may be a short-term strong wind in the working area, causing a fire or explosion accident. Failure to carefully check whether there is any residual fire after work.
2）The insulation of the welding cable or the welding machine itself has been damaged and caused a short circuit, causing a fire. The grease or paint on the workpiece to be welded has not been removed before welding.
3）If there is a certain concentration of dust (such as sulfur powder, flour, wood powder, coal powder, magnesium powder) in the working area, fire or explosion accidents may also occur during resistance welding operations.
4）Resistance welding machineThe operator did not use the welding machine according to the load endurance rate, and carried out overloading and overloading for a long time, which induced the temperature of the welding machine itself to rise, premature aging of the insulation, and even caused a short circuit in the coil and caused a fire.
5）The ground return line of the welding machine itself is overlapping in a disorderly manner. Due to poor contact, the resistance heat increases, which may also cause a fire or explosion accident, or a fire or explosion accident caused by the return line overlapping on a pipeline of flammable gas or liquid.
6）Resistance welding machineThe surface of the connection between the wires or the edge connection between the wire and the wiring board is rough and uneven, and there is oxide scale or the connection is loose, causing the local contact resistance to increase sharply and overheating, causing the copper core of the wire to discolor or even melt, causing a fire or explosion accident.

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.
