The welding process of the resistance welding machine is completed in 2 seconds. The editor of Xinxing often thinks that it is a simple matter, but it consists of 4 main stages: 1. Pre-pressure 2. Welding time 3. Maintenance time 4. Rest time

Why do we need to understand the heat distribution when welding with resistance welding machine? This allows everyone to better control them and equip them with suitable electrodes and cooling methods to weld good products faster and better.

Welding pressure is one of the three main factors of resistance welding machine. The relationship between resistance and pressure is not complicated. Let’s understand it with Xinxing editor.

In addition to flash butt welding machines, whether it is spot welding machine, projection welding machine, butt welding machine or seam welding machine, Xinxing says that the surface of the workpiece must be cleaned before operation. Why?

Not to mention that the small electrodes on the resistance welding machine are very useful, come in various styles, and require high materials. If they are worn, they often need to be repaired and replaced. They are consumable items on the welding machine.

Only by installing a more intelligent controller-type resistance welding machine can the butt welding machine have constant current control, constant voltage control and constant heat control. Xinxing's pneumatic spot welders, pneumatic butt welders, pneumatic projection welders, pneumatic seam welders and automatic welders all have this function.

Resistance welding includes: spot welding, butt welding, projection welding, and seam welding. Its principle is: place two metal workpieces between electrodes, press them tightly and then energize them. The current flows through the welding area and then uses the resistance heat of the workpiece itself to heat the workpiece, so that the welded part reaches a local melting or high-temperature plastic state.

For friends who have used resistance welding machines and butt welding machines, it goes without saying that they know the advantages, but they may not know them all. It is better to take a look with a novice.

Theoretically, almost all steel and non-ferrous metals can be flash butt welded, but to obtain high-quality joints, Xinxing Welding recommends taking necessary process measures based on the relevant characteristics of the metal.
