Ultrasound usually refers to a vibration wave with a frequency higher than 16kHz, that is, higher than the upper limit of artificial hearing frequency. The upper frequency range of the ultrasonic is mainly determined by the generator, and the actual use is within 5000MHz. Ultrasound, like sound waves, can propagate in gas, liquid and solid media, but due to its high frequency, short wavelength, and large energy, reflection, refraction, resonance and loss are significant during propagation.
Ultrasound has the following main properties
1.It can transmit very strong energy, and its energy density can reach more than 100W/m2;
2.It has a cavitation effect, that is, when the ultrasonic wave propagates in the liquid medium, it will locally produce a great impact force, instantaneous high temperature, material dispersion, crushing and various physical and chemical effects;
3.When passing through different media, there will be a sudden wave speed change at the interface, resulting in wave reflection, transmission and refraction;
4.It has sharp directivity, that is, when the ultrasonic transducer is set as a small disc, the sound intensity in the center normal direction is extremely large, and when it deviates from this direction, the sound intensity will be weakened;
5.Under certain conditions, interference and resonance of waves will occur.
Ultrasonic processing, also known as ultrasonic processing, can not only process brittle and hard metal materials, but also suitable for processing semiconductors and non-conductors such as glass and ceramics. At the same time, it can also be used in welding, cleaning, etc.
Ultrasonic processing has many applications in welding and cleaning. Ultrasonic welding is a pressure welding method in which two weldments are under pressure, using the high-frequency oscillation of ultrasonic waves to produce strong friction on the contact surface of the weldment, the surface is cleaned, and the welding is locally heated to increase the temperature. When used for plastic welding, the direction of ultrasonic vibration is the same as the direction of static pressure, while in metal welding, the direction of ultrasonic vibration is perpendicular to the direction of static pressure. Vibration modes include longitudinal vibration, bending vibration, torsional vibration and so on. The joint can be a solder joint, which overlaps the solder joints to form a continuous welding seam. The linear sonotrode is welded into a straight weld at a time, and the ring sonotrode is welded into a circular ring, a box shape, and other closed welds at one time. Corresponding welding machines include ultrasonic spot welding machine, seam welding machine, wire welding machine, and girth welding machine. Ultrasonic welding is suitable for welding metals with high electrical conductivity and high thermal conductivity, as well as welding dissimilar metals, metals and non-metals, plastics, etc., and can also weld gold foil as thin as 2μm. It is widely used in microelectronics, micromotors, aluminum products industry and aviation , Aerospace field.
