In addition to the limitation that the welded metal parts cannot be too thick, the welding spot cannot be too large, and the need to pressurize is unexpected. Compared with other welding technologies, modern ultrasonic metal welding machines have many irreplaceable advantages. Below, we will make a small series of ultrasonic waves to list them.

　1. Quality assurance and high reliability

　Through time, energy star, power and high limit monitoring, excellent process control and welding accuracy can be guaranteed. Vertical (non sector) pressurization system can overlap two objects to be welded, and ultrasonic vibration pressurization can be used to synthesize solid connection. The bonding time is short and the bonding part does not produce casting fabric (rough surface) defects. The welding position is uniform and easy to adjust. 

    2. Long service life of welding die

　Ultrasonic metal welding machine tools are made of high-quality tool steel, with excellent wear resistance, easy installation and high welding accuracy; Compared with the resistance welding method, the die has a long service life, less time for die repair and replacement, and is easy to realize automation.

　3. Low energy consumption and cost saving

　Ultrasonic metal welding machine avoids consumables such as solder, flux, bending and brass materials, making ultrasonic welding the most cost-effective welding technology. 

    4. Low temperature cold welding

　Ultrasonic welding can minimize the temperature effect of materials (the temperature of the welding area does not exceed 50% of the absolute melting temperature of the metal to be welded), so that the metal structure will not change. Therefore, it will not anneal the metal workpiece, melt the plastic shell, or require cooling water, so it is very suitable for welding applications in the electronic field. In terms of energy consumption, ultrasonic welding can be carried out between the same metal and different metals, which consumes much less energy than electrical welding.

　5. High efficiency and automation

　The typical welding time of ultrasonic metal welding machine is less than 0.5 seconds, with small size, less maintenance workload and strong adaptability, making ultrasonic equipment the first choice for automatic assembly line;

　6. It can realize welding of dissimilar metals

　Ultrasonic welding has excellent welding penetration and mixing effect for different or similar metals (such as copper copper or aluminum copper). 7. Easy and convenient welding

　Ultrasonic metal welding machine can handle ultrasonic welding without external factors such as flux, metal filler, external heating, etc. In most cases, the high-frequency friction of ultrasonic welding makes it unnecessary to pre clean the workpiece surface.

　Finally, after welding, the conductivity is good, and the resistance coefficient is very low or near zero. No spark in welding, environmental protection and safety. These two are also advantages of modern ultrasonic metal welding machine.
