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 stage 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.
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.
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.
