Benefits and characteristics of ultrasonic welding

The ultrasonic welding machine consists of five parts: program control and protection circuit, ultrasonic generator, ultrasonic sensor vibration and radiation system, pneumatic system and frame.

Benefits: 1. High fusion strength; close to cold working, no annealing of workpiece, no trace of oxidation; good electrical conductivity after welding, very low or close to zero resistance; low external requirements for welding metal, oxidation or electroplating;

2. The soldering time is short and does not require any flux, gas or solder.

3. Non-spark welding, environmentally safe.

Features:

1. The two welded parts are stacked and decomposed into a solid state by ultrasonic vibration crimping. The connection time is short, and the joint does not cause a forged structural defect (rough surface).

2. Compared with resistance welding, ultrasonic welding has the advantages of long service life, short mold repair and replacement time, and easy completion.

3. Ultrasonic welding can stop between different metals of the same metal, which consumes less energy than electrical welding.

4. Compared with residual pressure welding, the pressure required for ultrasonic welding is small and the variation is less than 10%, while the deformation of the cold welded workpiece is 40%-90%. 5. Ultrasonic welding does not require pre- and post-weld treatment outside the weld as other welds.

6. Ultrasonic welding requires no external marking, such as flux, metal filler, external heating, etc.

7. Ultrasonic welding minimizes the temperature effect of the material (the temperature in the weld zone does not exceed 50% of the relative melting temperature of the weld metal) to avoid changing the metal layout. It is a welding application that is very suitable for use in the electronics field. The voltage protection system (supply voltage range 180V~260V) does not affect the output power and operating frequency of the unit during automatic constant voltage.
