Introduction

Ultrasonic welding is a widely adopted technique for joining materials using high-frequency ultrasonic acoustic vibrations. This article provides an in-depth look at how ultrasonic card welders function, the solutions offered by Powersonic, and the technical parameters involved.

Principles of Ultrasonic Welding

Ultrasonic welding uses high-frequency vibrations to generate heat and join materials. It involves converting electrical energy into mechanical vibrations, which create localized heat through friction, fusing the materials at the interface.

Working Mechanism of Ultrasonic Card Welder

An ultrasonic card welder operates based on the application of ultrasonic frequencies, typically ranging from 20 kHz to 40 kHz. These frequencies are applied through a welding horn, which precisely directs the vibrations to the materials being joined. The welding process consists of the following steps:

1. Clamping: The materials are held together under pressure using a fixture that ensures proper alignment.
2. Vibration: The ultrasonic horn applies high-frequency vibrations, causing the material molecules to intermingle at the joint interface.
3. Welding: Friction generates heat that softens the material, forming a solid-state weld without melting the top layer.
4. Cooling: The pressure is maintained as the material cools and solidifies, ensuring a robust joint.

The efficiency of ultrasonic welding depends on factors such as material thickness, amplitude of vibration, and duration of welding.

• Precision: Enables precise control over weld parameters, ensuring consistent results.

It is widely applied in industries such as electronics, automotive, and medical device manufacturing, where precision and speed are crucial.

Numerical Analysis

The performance of ultrasonic card welders can be analyzed using specific parameters. For instance, a typical ultrasonic welder might operate at:

• Frequency: 20 kHz
• Amplitude: 10-50 µm
• Welding Time: 0.1 to 1 second
• Power Output: 500 to 5000 watts

By optimizing these parameters, manufacturers can achieve optimal joint strength and efficiency.
