Ultrasonic metal welding is a special method of connecting the same metal or dissimilar metals by using the mechanical vibration energy of ultrasonic frequency. When the metal is ultrasonically welded, neither the current is supplied to the workpiece nor the high-temperature heat source is applied to the workpiece, but the vibration energy of the frame is converted into the friction work, the deformation energy and the limited temperature rise of the work chamber under static pressure. . The metallurgical bond between the joints is a solid state welding realized without the base material melting. Therefore, it effectively overcomes the phenomenon of spatter and oxidation generated during resistance welding. Ultrasonic metal welding machine can perform single point welding, multi-point welding and short strip welding on filament or sheet material of non-ferrous metals such as copper, silver, aluminum and nickel. Can be widely used in thyristor leads, fuse sheets, electrical leads, lithium battery pole pieces, pole welding.
Any company's ultrasonic welding machine has a center frequency, such as 20Khz, 40khz, etc. The working frequency of the welding machine is mainly determined by the mechanical resonance frequency of the transducer, the horn, and the welding head. The frequency of the generator is based on the mechanical resonance. The frequency is adjusted to achieve consistency, so that the horn operates in a resonant state, and each part is designed as a half-wavelength resonator. Both the generator and the mechanical resonance frequency have a resonant operating range, such as a general setting of ±0.5Khz, in which the welding machine can basically work normally. When we make each welding head, we will adjust the resonant frequency. It is required that the resonant frequency and design frequency error is less than 0.1khz. For example, the 20khz welding head, the frequency of our welding head will be controlled at 19.9-20.1khz, and the error is less than 5%.
