摘要
Ultrasonic brazing is an innovative application of power ultrasound in brazing. The conventional brazing processes are improved or even changed by the physical and chemical effects of ultrasound. Thus, ultrasonic brazing is used as a new method to achieve the bonding of dissimilar materials by using the mechanical vibration energy and static pressure of ultrasound frequency. The characteristics of power ultrasound and ultrasonic brazing are reviewed in this article. The mechanism of ultrasound in the brazing process is analyzed in detail. The latest ultrasonic brazing technologies are introduced. Applications of ultrasonic brazing in the joining of dissimilar materials are summarized emphatically. Besides, several shortcomings of current research are listed in this paper. Some recommendations for the future development of ultrasonic brazing are given.
