The converters corresponding to your INVOICE NO. HS2015021 work very well. We would like to order more

—— Peter

I'm very happy with your good communication skills as well as follow up and good deal. I will definitely inform you my further program for further coo

—— Vinay

We tested it and it worked.  I will let you know about future purchases soon.

—— Alvin

Thank you! It is a pleasure, to work with a company that wants to make it right for the customer :) many times i deal with Chinese companies that do not care about the customer and long term business. I think I made the right decision going with you and Altrasonic !!!

Why Can Ultrasonics Weld Metal Products?


In today's digital age, electronic products are not very unfamiliar to everyone, and may be often used in ordinary times, and the core part of them is completed by metal welding.


Nowadays, metal welding is not just simple welding, but is carried out by ultrasonic waves. What is the difference between this welding technology and some traditional welding technologies, and how should it be operated?


Why ultrasonic can be used for welding?


Ultrasonic welding is the conversion of 50/60 Hz current into 15, 20, 30 or 40KHz high frequency electrical energy through an ultrasonic generator. The converted high-frequency electrical energy is converted into mechanical motion of the same frequency again by the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded, where the vibration energy is converted into heat energy by friction, melting the plastic. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer/horn/horn triplet, die and frame.


The principle of ultrasonic metal welding is a special method of using the mechanical vibration energy of ultrasonic frequency (over 16KHz) to connect the same metal or dissimilar metal. When the metal is ultrasonically welded, it neither transmits current to the workpiece nor applies a high temperature heat source to the workpiece, but under static pressure, the wire frame vibration energy is converted into friction work, deformation energy and limited temperature rise between the workpieces. . The metallurgical bond between the joints is a solid-state welding realized without the base metal melting. Therefore, it effectively overcomes the phenomenon of spatter and oxidation during resistance welding. Ultrasonic metal welding machine can perform single-point welding, multi-point welding and short-strip welding of copper, silver, aluminum, nickel and other non-ferrous metal filaments or sheet materials. It can be widely used in the welding of thyristor leads, fuse pieces, electrical leads, lithium battery pole pieces and tabs.


Welding products will involve more and more areas, and the technology will continue to improve. In metal welding, ultrasonic welding will become the mainstream trend in the future and be widely used.
