The iron ring and copper ring pneumatic butt welding machine isResistance welding machineOne of them, when welding different materials such as steel rings, iron rings, aluminum rings, copper rings, D-rings, galvanized buckles, chains, etc.
, some parameter settings are different, and trial welding must be constantly adjusted to meet the requirements, but the welding process is basically the same.
Let’s take a look with the editor of Xinxing Welding The welding process of iron ring copper ring pneumatic butt welding machine is mainly divided into three stages (1) Preload preparation 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) Electric heating 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 (pushing) 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.
