What are the 7 characteristic functions of an ultrasonic metal welding machine
7 features of ultrasonic metal welding machine. Ultrasonic metal welding was discovered by accident in the 1830s. It is similar to friction welding, but there are differences. Ultrasonic welding takes a short time and the temperature is lower than recrystallization; it is also different from pressure welding.
(1). The two objects to be welded are overlapped and joined into a solid form by ultrasonic vibration and pressure. The joining time is short and the joining part does not produce cast structure (rough surface) defects.
(2) Compared with ultrasonic welding and resistance welding, the mold life is long, the mold repair and replacement time is less, and it is easy to realize automation.
(3) Ultrasonic welding can be carried out between the same metal and different metals, which consumes much less energy than electric welding.
(4) Compared with other pressure welding, ultrasonic welding requires less pressure, and the deformation amount is less than 10%, while the deformation of the workpiece in cold pressure welding is 40%-90%.
(5) Ultrasonic welding does not require pre-treatment of the welded surface and post-weld treatment like other welding.
(6), processing ultrasonic welding does not require external factors such as flux, metal filler, external heating, etc.
(7) Ultrasonic welding can minimize the temperature effect of the material (the temperature of the welding zone does not exceed 50% of the melting temperature of the welded metal), so as not to change the metal structure, so it is very suitable for welding applications in the electronic field.
