Whether it is a fixed spot welding machine, a handheld spot welding machine, a hanging spot welding machine, a semi-automatic butt welding machine or a flash butt welding machine, its joints are all different and each has its own characteristics. Let’s take a look.

The power supplies of flash butt welding machines, classic butt welding machines, pneumatic spot welding machines, etc. have evolved from gear type to stepless type and then to inverter type. They are constantly upgraded. They are getting smaller and smaller, lighter and lighter. They have more and more advantages and are becoming more and more popular among large enterprises!

The electrical appliances of flash butt welding machines and CNC butt welding machines are controlled by traditional relays, contactors and gear switches. They are upgraded to digital controllers + thyristor contactless switches. There are many advantages. Please see for details.

As the name suggests, the oil-water separator is a device that separates oil and water. It is also called a two-part device. When the flash butt welding machine is used, the compressed air passes through it, causing a sharp change in the flow direction and speed. Relying on the action of inertia, the oil-water separator separates oil droplets and water droplets that are denser than the compressed air.

The water flow diversion monitor in the flash butt welding machine, some are also called diversion controllers or water drains, have precise scales to display the temperature and better regulate the water flow. Please come with me to see the details.

Whether it is resistance spot welding, butt welding, arc welding, laser welding, etc., the workpiece is heated and cooled unevenly during the welding process, resulting in different degrees of thermal expansion and cooling contraction of the welded piece, resulting in stress and deformation. So how to prevent and eliminate it?

When the flash butt welding machine butts the workpieces, it goes through the preheating stage, enters the flash stage and then enters the upsetting stage. A series of actions complete the welding. What is their basic function?

The upsetting force and cylinder clamping force of flash butt welding machines are actually very demanding, especially the clamping force, which is 1.5-4 times the upsetting force. This requires the cylinder to be larger than that of ordinary pneumatic butt welding machines and pneumatic spot welders. However, there are really not many flash butt welding machines on the market that meet the requirements. So what are the specific parameters?

The flash speed and upsetting speed in the flash butt welding machine must be adjusted slowly according to the material and size of the workpiece. So what is the required standard speed? There is still a lot of data, so let’s take a look at the detailed data with the editor of Xinxing Welding.
