Problems solved by technology

[0003] Ordinary spot welding of enameled wire is to use the upper and lower welding electrodes to puncture the enameled wire, and then weld. This welding method is easy to damage the enameled wire. Two side-by-side welding electrodes are fixed on the electrode holder, and the heads of the welding electrodes are connected into one body. When the welding electrodes are energized, the enameled wire is melted first, and then the welding operation is performed.

The current enameled wire welding basically uses this kind of welding electrode to solve the problem of enameled wire damage. However, the welding electrode itself connected to the head of this kind of enameled wire is a resistor, which has problems of shunt, loss and oxidation. The diameter of the usual enameled wire is in the Below 0.1mm, this cross-sectional area is much smaller than the cross-sectional area of ​​the welding electrode head connection. Since the voltage is the same, the larger the cross-sectional area, the smaller the resistance, the greater the current flowing, and the greater the shunt effect of the welding electrode head. The greater the energy loss at the same time, because the electrode bears most of the shunt, the welding electrode head is easily oxidized, and the loss is very fast. The loss of the welding electrode causes its cross-sectional area to change, and the resistance of the welding electrode head also changes, resulting in inconsistent welding parameters. The welding temperature is unstable due to stability, and welding parameters need to be adjusted frequently, so the welding efficiency is low, the welding consistency of the product is poor, and the qualified rate is low
