Функція зварювальної машини опору

The main function of resistance welding machine is to weld metals by the principle of resistance heat. Specifically, the resistance welding machine applies a certain pressure to the workpiece to be welded and passes a large current at the same time, so that the resistance between the contact surfaces of the workpieces generates heat. This heat is enough to melt the metal on the contact surface and form a weld, thereby Досягнення зварювання .
