The principle of ultrasonic metal welding process
During the metal welding process, tens of thousands of high-frequency vibration waves per second is transferred to two metal workpiece surface, and then impose a certain pressure on it, so that the metal surface friction and the formation of fusion between molecular layers, to achieve the purpose of metal welding.
The advantages of ultrasonic metal welding machine
1. Ultrasonic metal welding has high fusion strength;
2. The metal welding process is close to cold processing, workpiece no annealing, no oxidation trace;
3. After metal welding, the electrical conductivity is good, and the resistance is better than other welding processes
4. It has low requirements for welding metal surface, and oxidation or electroplating can be welded;
5. The metal welding time is short and the working effiency is high. Do not need any flux, gas, solder.
6. The whole metal welding process does’n have spark, it is eco-friendly.
The disadvantages of ultrasonic metal welding machine
The welded metal can not be too thick, solder joints can not be too large, need to be pressurized.
The application of ultrasonic metal welder
Ultrasonic metal welding machine can weld copper, silver, aluminum, nickel and other non-ferrous metal wire or thin sheet materials for single point welding, multi-point welding and short strip welding. Ultrasonic welders can be widely used in silicon controlled lead, fuse piece, electrical lead, lithium battery pole piece, pole ear welding.
