What are the components of ultrasonic metal welding machines, and what are the advantages and disadvantages of ultrasonic metal welding machines? Deep Source will tell you one by one

Release time:2019-09-30

Ultrasonic metal welding machineIt mainly consists of the following components:
Generator, pneumatic component, program control component, and transducer component.

The main function of the generator is to convert the 50Hz power supply into high-frequency (such as 20KHZ) high-voltage radio waves through electronic circuits.

The main function of pneumatic components is to complete pressure work such as pressurization and pressure holding during the machining process.

Program control controls the workflow of the entire machine to achieve consistent processing results.

The transducer converts the high-voltage electrical waves generated by the generator into mechanical vibrations, which are transmitted, amplified, and reach the machining surface.

The advantages of ultrasonic metal welding:

Fast welding speed;

High welding strength;

Low energy consumption required;

The welding process is convenient and pollution-free, without the need for other auxiliary equipment;

Welding equipment has a small volume and is convenient to use.

Disadvantages of ultrasonic metal welding:

1: Can only weld small amounts of metals such as aluminum, magnesium, and copper; 2: Can only weld metal sheets and thin metal wires; 3: High requirements for the shape of welding materials;

(1) The two welded objects overlap and are combined into a solid form through ultrasonic vibration pressure bonding. The bonding time is short, and the bonding part does not produce casting structure (rough surface) defects.

(2) Compared with resistance welding methods, ultrasonic welding has a longer mold life, less time for mold repair and replacement, and is easy to achieve automation.

(3) Ultrasonic welding can be performed between the same metal and different types of metal, which consumes much less energy compared to electrical welding.

(4) Compared with other pressure welding methods, ultrasonic welding requires lower pressure and less than 10% deformation, while cold pressure welding requires a workpiece deformation of 40% -90%.

(5) Ultrasonic welding does not require pre-treatment of the welded surface and post-weld treatment like other welding methods.

(6) Ultrasonic welding does not require external factors such as flux, metal filler, or external heating.

(7) Ultrasonic welding can minimize the temperature effect of materials (the temperature in the welding zone does not exceed 50% of the absolute melting temperature of the welded metal), thereby preventing changes in the metal structure, making it very suitable for welding applications in the electronic field. High fusion strength;

Near cold processing, no annealing of the workpiece, and no oxidation marks;

Good conductivity after welding, with extremely low or almost zero resistance coefficient;

Low requirements for welding metal surfaces, both oxidation and electroplating can be used for welding;

Short welding time, no need for any flux, gas, or solder.

Welding without sparks, environmentally friendly and safe. The welded metal parts should not be too thick, and the welding points should not be too large. Pressure should be applied.
