Copper and aluminum pipes are also called sleeve joints and copper-aluminum connecting pipes. They are mainly welded with special butt welding machines, such as pneumatic copper and aluminum pipe welding machines and automatic copper and aluminum pipe butt welding machines produced by Xinxing Welding. They are mainly used in refrigeration industries such as refrigerators and air conditioners. Their requirements are relatively high and there are many inspection items.

Before looking at the welding process of the copper-aluminum pipe butt welding machine, let's talk about why we use copper-aluminum pipes. It is to weld a section of copper pipe, that is, a copper-aluminum pipe, at both ends of the aluminum pipe. In this way, the copper pipe is still connected to the copper valve during installation, because there will be no corrosion problems.

The welding process of Xinxing copper and aluminum pipe butt welding machine is the action state of each component. It includes several different actions in completing an action cycle, and then determines the switching signal after each action.

The copper-aluminum pipe butt welding machine in the resistance pneumatic butt welding machine is widely used in refrigeration industries such as refrigerators and automobile air conditioners. It is a special equipment for welding copper and aluminum pipe joints. There are standard machines, non-standard machines and high-end machines.

Why do some spot welding machines have the same power but different welding workpiece specifications?

Everyone knows that logistics in our country is getting faster and faster, and prices are becoming more and more affordable. If it were you, would it be efficient if you opened branches across the country? Is it affordable? The same is true for butt welding machine manufacturers.

Copper and aluminum pipe butt welding machines are a type of resistance welding machine. Due to the use of pneumatic pressure, also known as pneumatic butt welding machines, they can weld copper and aluminum pipes in seconds, but not all copper and aluminum pipes can be welded together.

The Xinxing copper and aluminum pipe butt welding machine is different from the semi-automatic butt welding machine in that it has a more complex and intelligent control system, waterway system and pneumatic system. It is also called a cabinet type pneumatic butt welding machine. Its control system adopts digital closed-loop control to automatically control the welding process, thereby reducing the labor intensity of the welder, ensuring the welding quality, and reducing the operational technical requirements for the welder.

In addition to being able to butt copper and aluminum pipes, the Xinxing copper and aluminum pipe butt welding machine can also butt metal bars, flat materials, etc. by replacing the electrodes. It uses compressed gas to press upset and water-cool for heat dissipation, so it is also called a water-cooled pneumatic butt welder. The structure is relatively complex, the automation process is high, and it is difficult to malfunction.
