900w Ultrasonic Handheld Spot Welding Machine in 20Khz with Customized Titanium Welding Horn
Description:
QRsonic can supply 20khz, 28khz, 30khz, 35khz, 40khz ultrasonic spot welding machine with digital generator.
Ultrasound can be used not only to weld hard thermoplastics, but also to fabrics and films. The main components of a set of ultrasonic welding systems include ultrasonic generators, transducer/amplifier/welding head triples, molds and frames.
The principle of Ultrasonic spot welder welding is to convert 50/60 Hz current into 20, 28, 35 kHz electric energy through ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into a mechanical motion of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude.
The horn transfers the received vibrational energy to the joint of the workpiece to be welded, in which the vibrational energy is converted into thermal energy by friction to melt the plastic.

What are the characteristics of ultrasound?
Our ears can only distinguish sounds with a frequency of 20 to 20,000 Hz. Sound waves with a frequency higher than the human hearing frequency range are one of the categories of sounds. They belong to mechanical waves. Sound waves mean that the human ear can feel a kind of longitudinal wave. The frequency range is 16Hz-20KHz. When the frequency of sound waves is lower than 16Hz, it is called infrasound wave. When it is higher than 20KHz, it is called ultrasonic sound wave. Ultrasonic wave has the following characteristics:
1. Ultrasonic waves can be effectively propagated in media such as gases, liquids, solids, and solid solutions.
2. Ultrasound can transmit very strong energy.
3. Ultrasound produces reflection, interference, superposition and resonance.
4. When ultrasonic waves propagate in a liquid medium, strong impact and cavitation can occur at the interface.
