Q: What’s the metal welding?
A: Ultrasonic metal welding was discovered by chance in the 1930s. It is similar to friction welding, but with the difference that the ultrasonic welding time is short and the temperature is lower than recrystallization; it is not the same as pressure welding because the static pressure applied is much smaller than that of pressure welding. It is generally believed that in the initial stage of the ultrasonic welding process, the oxide is tangentially vibrated out of the metal surface, and the protruding portion of the rough surface generates repeated micro-welding and destruction processes to increase the contact area and simultaneously increase the temperature of the soldering zone. High, plastic deformation occurs at the interface of the weldment. In this way, under the action of the contact pressure, the solder joints are formed when they approach each other to a distance at which the atomic attraction can act. The welding time is too long, or the ultrasonic amplitude is too large, so that the welding strength is reduced or even destroyed.
