Butt welding machine at field working in China is a kind of resistance welding machine. When welding steel ring, iron ring, aluminum ring, copper ring, D-ring, galvanized clasp, chain and other materials, some parameter settings are different. Keep adjusting the test welding to meet the requirements, but the welding process is basically the same.
But welding machine at field working in China
(1) Preloading preparation
The preloading is to establish a good and evenly distributed physical contact point. Therefore, the welding end face of the workpiece and the current introduction surface should be kept clean, and their end faces should be connected at 0 ° as far as possible to ensure that the initial contact point is as uniform as possible. For workpieces with large section difference, the shape and size of smaller workpieces shall be machined at the port of larger workpieces before welding, so that the temperature can reach uniform distribution quickly.
(2) Electrically heated
Resistance butt welding Under the combined action of pressure and resistance heat, the 2 end faces are rapidly heated and liquefied, making the contact area increase, and finally extend to the entire joint surface, so that the contact resistance tends to zero, and the workpiece resistance increases with the rise of temperature. 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, while under the action of pressure, the workpiece gradually produces plastic deformation and shortens.
(3) Upset forging
When the temperature of the end face of the workpiece tends to be uniform and a certain temperature distribution is formed along the depth of the end of the workpiece, the upset forging stage is started at this time, and the welding machine automatically stops energizing for upset forging.
In actual use, heating and upsetting are often completed automatically, and only the stop button is needed after the completion.
