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 !!!

What are the disadvantages of ultrasonic metal welding machine
Latest company news about What are the disadvantages of ultrasonic metal welding machine

Ultrasonic metal welding was discovered by accident in the 1930s. At that time, during the current spot welding electrode plus ultrasonic vibration test, it was found that it could be welded without current, so the ultrasonic metal cold welding technology was developed. Although ultrasonic welding has been discovered earlier, its mechanism of action is not very clear so far. Ultrasonic metal welding has also produced some drawbacks in its development process, which is worthy of attention and research and improvement. These shortcomings are manifested in the following aspects:

1. There are problems with the system
In the welding process of ultrasonic metal welding technology, it is necessary to realize the cooperation of multiple cooperative systems to form a tightly integrated overall system. This system includes an ultrasonic generator, an acoustic system and a mechanical system. If the coordination degree and coordination degree of the whole system are inconsistent, it will cause certain problems in the stability, operability and reliability of the system.

 

2. The welding machine is difficult to manufacture and its mechanism is not well understood.
Since the ultrasonic metal welding technology can weld high-density and high-thickness metals and dissimilar metals, the manufacturing requirements for welding machines that implement this technology are relatively high. Compared with traditional welding machines, the manufacturing process of ultrasonic metal welding machines is more difficult and costly, and because there are many factors that affect welding process parameters, it is not easy to understand and summarize the mechanism of welding machines.


3.'Openness' is poor and prone to high frequency vibration
The "openness" of the ultrasonic metal welding machine is relatively poor, and its extension size is strictly limited to the range allowed by welding, and its joint form is still limited to lap joints, and no further breakthroughs have been made in technology. At the same time, the welding point of the ultrasonic metal welding machine is prone to high-frequency vibration, which may cause damage to the edges of the product workpiece, especially hard and brittle materials.

 

4. Difficult to detect
For the current development of ultrasonic metal welding technology, it is still difficult to detect the quality of welding products, and the matching testing equipment has not been popularized, and the testing methods suitable for traditional welding technology cannot be applied to new technologies. If the detection technology cannot keep up, it creates certain difficulties for mass production.
