Ultrasonic Transducer for Welder
Ultrasonic transducer is a piezoelectric ceramic resonant to ultrasonic frequency, which converts electrical signals into mechanical vibration by the piezoelectric effect of the material.
When the ultrasonic plastic welding machine is welding plastic workpieces, the plastic workpieces need high-frequency longitudinal vibration, so that the upper and lower molds of the plastic workpieces can be melted by high-frequency vibration, forming the welding effect. Therefore, the ultrasonic transducer for welder generally selects the longitudinal composite type. The structure of the transducer is relatively simple. There are two metal cover plates on both sides of the head and tail, and the middle is composed of piezoelectric ceramic crystal stacks. These crystal stacks are generally circular tubes with longitudinal polarization or circular holes. Of course, they may also be circular tubes with radial polarization. These three parts are tightly fixed by a stress screw.
FAQ：
Q：Why do ultrasonic transducer for welder often break?
There are only three reasons:
1. The quality of ultrasonic welding machine is defective;
2. In the process of use (due to the failure to adjust the mold before the use of the ultrasonic welding machine, or the long-term overload operation, or the poor quality of the mold), the transducer is seriously heated.
3. There are three reasons why the handle is broken. It is recommended to use the hand welding machine of jiayuanda company. The welding wire of the hand welding machine of jiayuanda is imported lead-free solder wire, which is not easy to fall off. The handle is made of engineering plastic, which is resistant to high temperature and beating. In addition, the high-quality transducer is selected, so the failure rate of the handle is very low.

Q: Will the ultrasonic generator break when turned on without connecting to the Ultrasonic Transducer for Welder
Yes. (1) The indicator light of the ultrasonic generator is not on, the fan does not turn: the power switch is broken; The power fuse is blown.
(2) The indicator light of the ultrasonic generator is on, the fan is running normally, and there is no ultrasonic: the connection plug between the ultrasonic transducer and the ultrasonic output is loose; DC fuse blown; The bridge of the ultrasonic generator is damaged; The IGBT of the ultrasonic generator power tube is damaged; Short circuit of ultrasonic transducer.
(3) Turn on the power switch of the ultrasonic generator, and the overload light will be on: the insulation resistance of the ultrasonic transducer is too low; Short circuit or grounding of the cable connecting the ultrasonic transducer; Short circuit of boost transformer.
Q：What is the smoke between the mold head and the ultrasonic transducer machine ?
It may be that the transducer is broken. Just check it and remove the mold and detect the sound wave. And then you can quickly judge it
