Description:
Ultrasonic metal welding is a fast, clean and economical technology that is widely used in various automation industries.
The ultrasonic metal welding process is a process between cold press welding and friction welding that utilizes high density energy generated by high frequency mechanical vibration. The mechanical vibration of the welding head of the ultrasonic metal welding is parallel to the surface of the workpiece. During welding, the static pressure acts perpendicularly on the welding surface through the welding head, and at the same time superimposes the shearing force of the high-frequency vibration. When the shearing force exceeds the elastic limit of the material, the part of the contact surface of the workpiece begins to slip. This shearing force During the welding process, the direction is continuously changed at a frequency of tens of thousands of times per second, and the dirt on the surface of the workpiece is broken and removed. The surface of the pure metal begins to contact in multiple points. With the continuation of high-frequency vibration, the area of pure metal is continuously expanded. Until it expands into the entire weld zone, at the same time atom diffusion occurs on the contact surface, and the metal recrystallizes to form a fine grain structure and exhibits cold metal deformation characteristics.
Principle:
Ultrasonic metal welding uses high-frequency vibration waves to transmit to two metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other to form a joint between the molecular layers. The advantage is that it is fast, energy-saving, High fusion strength, good electrical conductivity, no spark, close to cold processing; the disadvantage is that the welded metal parts should not be too thick (generally less than or equal to 5mm), the solder joints should not be too large, and need to be pressurized.

Amplitude parameter:
The amplitude is a key parameter for the material to be soldered, which is equivalent to the temperature of the soldering iron. If the temperature is not reached, the welding will not be possible. If the temperature is too high, the raw material will be burnt or the structure will be destroyed and the strength will be deteriorated. Because the transducers selected by each company are different, the amplitude of the transducer output is different. After adapting the different ratios of the horn and the horn, the working amplitude of the horn can be corrected to meet the requirements. The output half-wavelength amplitude of the energy device is 5-10 microns, and the working half-wave amplitude is generally about 10-45 microns. The variation of the horn and the horn is related to the shape of the horn and the horn, the front-to-back area ratio and other factors. In terms of shape, such as exponential luffing, functional luffing, stepwise luffing, etc., the influence on the transformation ratio is large, and the front-to-back area ratio is proportional to the total transformation ratio. The different amplitudes required for welding different materials are generally determined experimentally to determine the desired amplitude.
