Ultrasonic metal spot welder
Jun 11 , 2021
Ultrasonic metal spot welder: It is similar to friction welding, but there are difference, Ultrasonic welding takes a short time and the temperature is lower than recrystallization; It is also different from pressure welding because the static pressure applied is much less than pressure welding. It is generally believed that in the initial stage of the ultrasonic welding process, the tangential vi...
