What are the types of ultrasonic metal welder?

Table of Contents

There are many different types of ultrasonic metal welding machines, each ultrasonic metal welder with its own specific application and advantages. By understanding different types and applying them, you can better improve your work efficiency and quality.

Ultrasonic metal welding machines with different frequencies

Ultrasonic metal welding machines are divided into three categories according to the frequency of the ultrasonic vibration they produce:

High frequency ultrasonic metal welder

High-frequency ultrasonic metal welding machines typically operate at frequencies above 50,000 hertz (50 kHz).

Higher frequencies allow for better control of the welding process, making these machines ideal for applications involving thin materials or precision parts. High frequencies enable precise and controlled welding where fine detail and accuracy are critical.

Common applications for high-frequency ultrasonic metal welding machines include microelectronics, medical equipment, and other industries that require precise joining of small or complex parts.

Medium frequency ultrasonic metal welder

Medium frequency ultrasonic metal welding machines operate at a frequency of 30,000 to 40,000 hertz (30-40 kHz).

This type of welding machine strikes a balance between precision and power. Medium frequency welding machines are typically chosen to join components of medium thickness, providing efficient and reliable welding in a variety of industrial environments.

Mid-frequency ultrasonic metal welding machines are suitable for a wide range of applications, including automotive, aerospace and electronics, where a combination of weld strength and detail is required.

Low frequency ultrasonic metal welder

Low-frequency ultrasonic metal welding machines operate at approximately 20,000 hertz (20 kHz).

Lower frequencies allow for greater material penetration, making low-frequency machines ideal for challenging welding scenarios involving large metal thicknesses, such as welding thicker materials or larger parts requiring higher power.

Common applications include the assembly of automotive parts, construction materials, and other situations where strong welding is required.

Ultrasonic metal welding machines for different uses

According to use, ultrasonic metal welding machine can be divided into: ultrasonic metal spot welding machine, ultrasonic metal seam welding machine, ultrasonic metal sealing and cutting machine, ultrasonic metal wire harness welding machine, referred to as spot welding, seam welding, sealing and cutting, wire harness.

Ultrasonic Metal Wire Harness Welding Machine

Wire harness welding machines are designed for connecting fine wires to metal surfaces, typically in electronics applications. These machines are widely used in the semiconductor industry for wire bonding, ensuring strong and reliable electrical connections.

Ultrasonic Metal Spot Welding Machine

Ultrasonic metal spot welding machines are designed for spot welding, where two metal components are held together, and a localized area is subjected to high-frequency vibrations and pressure. It’s commonly used in industries such as automotive, aerospace, and electronics for joining small or delicate parts.

Ultrasonic Metal Seam Welding Machine

Seam welding machines are used for creating continuous, hermetic welds along the length of two metal edges. These machines find applications in the manufacturing of pipes, tanks, and other cylindrical structures, providing leak-proof and durable welds for structural integrity.

Ultrasonic Metal Sealing Machine

Ultrasonic metal sealing machine is utilized for sealing metal tubes or components. It creates hermetic welds between metal parts, ensuring a tight seal. Industries such as pharmaceuticals, food processing, and cosmetics commonly use ultrasonic metal sealing and cutting machines to prevent leakage and contamination.

Ultrasonic Rolling Welding Machine

Ultrasonic rolling welding machines use ultrasonic vibrations in rolling motion to form strong and seamless bonds between metal parts. This innovative welding process is particularly effective for joining tubular or cylindrical structures, offering advantages in terms of efficiency and precision.

Ultrasonic rolling welding machines excel at joining metal pipes in oil and gas, automotive and construction applications. Furthermore, its versatility extends to battery manufacturing, heat exchanger production, aerospace components and even the assembly of solar panels for high-efficiency solar collector tubes.

Ultrasonic Rolling Welding Machine

Ultrasonic metal welding machines of different sizes

According to the size and operation method of the machine, it can be divided into:

Handheld ultrasonic metal welding machine

The handheld ultrasonic metal welder is a portable and lightweight device that can be easily carried around. Variants may include handheld spot welders, welders for fine wire applications, and compact devices for complex welding tasks.

Handheld welders are suitable for applications where mobility and flexibility are critical, allowing operators to perform precise welds in different positions, often used to weld small or complex metal parts.
Ideal for on-site repairs, small-scale production or where the welder needs to be brought to the workpiece, it is commonly used in industries such as electronics, jewelry and automotive repair.

Desktop Ultrasonic Metal Welding Machine

Benchtop welders are designed to be placed on a workbench or table. They are generally more stationary than handheld devices, providing a stable platform for performing metal welding operations. Compared with handheld welding machines, it has higher precision and is suitable for fine and complex welding.

Benchtop ultrasonic metal welders are ideal for applications that require a stable and controlled welding environment. Mainly used in laboratories, workshops and small and medium-sized production environments. Because desktop ultrasonic metal welders are often equipped with better control and precision features, they are suitable for applications such as electronics manufacturing, medical device assembly, and research and development.

Large ultrasonic welding machine

Large ultrasonic welding machines are industrial grade equipment designed to handle higher volume workloads and larger metal parts with high throughput and efficiency. Different configurations are available depending on the specific industrial application, including seam welding machines for continuous welding of metal strips, robotic welding systems for complex assemblies, and customized machines for specific mass production needs.

Large ultrasonic welding machines are typically automated or semi-automated and are suitable for high-volume production environments where efficiency and consistency are critical. Commonly used in automobile manufacturing, home appliance production, construction and other industries.
