Advantages and disadvantages of ultrasonic metal welding machine
Features:
1. The two objects to be welded are overlapped and joined by ultrasonic vibration and pressure to form a solid form. 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 absolute melting temperature of the welded metal), so that the metal structure does not change, so it is very suitable for welding applications in the electronic field.
advantage:
High fusion strength
close to cold processing, the workpiece is not annealed, and there is no trace of oxidation;
has good electrical conductivity after welding, and the resistivity is very low or almost zero;
has low requirements on the surface of the weld metal, and can be welded by oxidation or electroplating;
Any flux, gas, solder is required.
Welding without sparks, environmental protection and safety.
Disadvantages:
The metal parts to be welded should not be too thick, and the solder joints should not be too large, requiring pressure.
