The application of ultrasonic welding technology in the metal processing industry is mainly reflected in the ultrasonic metal welding machine as well as various special metal welding machines, such as copper aluminum welding machine. Ultrasonic welding has the advantages of short time, low energy consumption, nondestructive workpiece and high efficiency. Therefore, ultrasonic metal welding is widely used for single point welding, multi-point welding and short strip welding of non-ferrous metals such as copper, silver, aluminum, nickel, etc.
