What's the butt welding machine? What's the difference between it and welding?
Butt welding machine is flash butt welding machine. In construction, the welding of column reinforcement is useful. Flash butt welding machine using the instantaneous current arc ignition flux to produce high temperature melting steel joint, by pressurizing the two steel welded together.
Butt welding machine belongs to series of resistance welding machine. Broadly speaking, it also belongs to the category of electric welding machine.The upper and lower two water cooling electrodes are used for pressurizing, and a large current is used for a short time to cause the electrode to touch the parts to produce a nugget, and the no-load voltage is lower, so that the melting of the electrode and the bonding of the base metal are avoided. A welding process to the effect of welding.Narrow sense electric welding machine refers to the welding rod hand arc welding machine. Of or belonging to a fusion electrode (a welding electrode used as an electrode and fused and filled to form a weld). The no-load voltage and the working voltage are relatively high. The no-load voltage is high, easy to arc; the work voltage is high, easy to electrode (welding rod) melting. And ensure the weld penetration.
Generally, the welding machine does not use electrodes, and the two parts of the metal are welded togetherCommonly used resistance welding - the use of high contact resistance, in the case of electricity, so that the contact material temperature increased to the point near the melting point, and then pressurized to make it togetherThere is also friction welding, which uses two contact ends to rotate at high speed. The high temperature produced by friction causes the materials at the contact temperature to rise near the melting point and then press them together
