Description

Technical Field

[0002] The main principle of ultrasonic brazing is to directly apply the ultrasonic transducer to the surface of the workpiece near the welding position, transmit the ultrasonic vibration into the brazing material through the workpiece, and use the mechanical effect of ultrasound to make the brazing material spread and wet on the workpiece surface and combine with the parent material. This technology is mainly used for welding dissimilar metals. The use of ultrasonic cavitation in the atmospheric environment can remove the oxide film, improve production efficiency and reduce manufacturing costs.
