Three stages of the welding process of CNC metal wire butt welding machine
Release time:2022.03.03
Summary of information:
CNC metal wire butt welding machine is a new type of CNC resistance butt welding machine, single wire butt welding machine, and mobile butt welding machine. The model of Xinxing Welding is UN3S. The procedures in the welding process are mainly three stages: pre-pressure, heating, and upsetting. 1. Preloading stage
CNC metal wire butt welding machine is a new type of CNC resistance butt welding machine, single wire butt welding machine,Mobile butt welding machineOne of them, the model used by Xinxing Welding is UN3S. The procedures during the welding process are mainly three stages: pre-pressing, heating, and upsetting.
Preloading is to establish good and evenly distributed physical contact points. Therefore, the welding end face of the workpiece and the surface where the current is introduced should be kept clean, and their end faces should be connected at 0 degrees as much as possible to ensure that the initial contact points are as uniform as possible. For workpieces with large cross-section differences, the shape and size of the smaller workpiece should be processed in advance at the port of the larger workpiece before welding, so that the temperature can reach a uniform distribution quickly.
2. Heating stage
Under the combined action of pressure and resistance heat, the two end faces of resistance butt welding are rapidly heated and liquefied, causing the contact area to increase and finally expand to the entireA joint surface, so that the contact resistance tends to zero, while the workpiece resistance increases as the temperature rises. Under the action of heat conduction, the end surface temperature tends to be uniform, and a certain temperature distribution is formed along the depth of the end of the workpiece. At the same time, under the action of pressure, the workpiece gradually undergoes plastic deformation and shortens.
3. Upsetting stage
When the temperature of the end face of the workpiece tends to be uniform and a certain uniform temperature distribution is formed along the depth of the end of the workpiece, it enters the upsetting stage. At this time, the welding machine automatically stops powering for upsetting.
In actual use, heating and upsetting are often completed automatically. After completion, just press the stop button.

What should be done to the workpiece before using the UN6 water-cooled butt welding machine?
Summary of information:
The UN6 water-cooled butt welding machine can connect a lot of metal materials, such as copper rods, aluminum rods, titanium rods, steel rods, copper tubes, aluminum tubes, copper aluminum tubes, steel tubes, flat iron flanges, steel rows, copper rows, iron rings, copper rings, aluminum rings, etc. Because it is widely used for welding copper and aluminum pipes, it is called a copper-aluminum pipe welding machine in the factory. Before using this butt welding machine, the workpiece is usually
The UN6 water-cooled butt welding machine can connect a lot of metal materials, such as copper rods, aluminum rods, titanium rods, steel rods, copper tubes, aluminum tubes, copper aluminum tubes, steel tubes, flat iron flanges, steel rows, copper rows, iron rings, copper rings, aluminum rings, etc. Because it is widely used for welding copper and aluminum pipes, it is called a copper-aluminum pipe welding machine in the factory. Before using this butt welding machine, the workpiece usually needs to do the following work:
1. Pay attention to the end face geometry
When butt welding, the geometric shape and size of the butt surfaces of the two workpieces should be basically consistent for at least 2mm. Otherwise, it will be difficult to achieve thermal balance and the heating and plastic deformation of the two workpieces cannot be guaranteed to be consistent, which will affect the quality of the joint. In production, the difference in diameter of round workpieces should not exceed 15%, and the difference between square workpieces and tubular workpieces should not exceed 10%.
2. Precautions for welding dissimilar metals
When welding different metals, the length of the metal with better thermal conductivity extending out of the clamp should be longer, so that the current can pass through the longer metal and increase heat generation, thereby achieving thermal balance. Metals with lower melting points should also extend longer because they burn faster. When copper and aluminum pipes are connected, the copper pipe mouth should be narrowed to keep it close to the aluminum pipe.
3. Clean the docking port surface
Clean the oxides on the workpiece port, such as rust stains, which have poor electrical and thermal conductivity, affect the flow of current, and the quality of the interface will deteriorate.
