Characteristics of ultrasonic metal welding machine
Apr 09, 2018

(1) the two welded objects overlap, and the solid form is synthesized by the ultrasonic vibration pressure, the joint time is short, and the joint part does not produce the casting tissue (rough surface) defect.

(2) comparison between ultrasonic welding and resistance welding method, the die life is long, the mold is repaired and replaced with less time, and it is easy to realize automation.

(3) ultrasonic welding can be performed between different metals of the same metal, which is much less energy than electric welding.

(4) compared with other pressure welding, ultrasonic welding requires less pressure, and the variation volume is less than 10%, while the deformation of the workpiece is 40% to 90% under cold pressure welding.

(5) ultrasonic welding does not require the pretreatment of welding surface and post-welding after welding as other welding.

(6) external factors such as flux, metal filler and external heating are not required for ultrasonic welding.

(7), to minimize the effect of ultrasonic welding can make the temperature of the material (the weld area temperature not to exceed 50% by welding the absolute melting temperature of metal), so as to not make the metal structure change, so it's suitable for welding applications in the field of electronics.
