Advantages of ultrasonic metal welding machine
Except that the metal parts to be welded should not be too thick and the solder joints should not be too large, the need to pressurize this limitation is unexpected. Compared with other welding techniques, modern ultrasonic metal welding machines have many irreplaceable advantages. The editor of Dezhalnick lists them one by one below.
1. Guaranteed quality and high reliability
Through time, energy, power and high limit monitoring, to ensure excellent process control, ensure welding accuracy, vertical (non-sector) pressure system, two objects to be welded overlap, they are connected by ultrasonic vibration to form a solid connection, and the joining time is short and No casting structure (rough surface) defects are produced in the joint part, the welding position is uniform and the adjustment is simple.
2. Long life of welding mold
Ultrasonic metal welding machine tools are processed by high-quality tool steel. They have excellent wear resistance, easy installation and high welding accuracy; compared with resistance welding methods, the mold life is long, the mold repair and replacement time is less, and it is easy to achieve 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 economical welding technology.
4. Low temperature cold welding
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 as not to change the metal structure, so it will not anneal the metal workpiece and will not make the plastic shell It melts and does not 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 type of metal and different types of metal, which consumes much less energy than electric welding.
5. High efficiency and high degree of automation
The typical welding time of the ultrasonic metal welding machine is less than 0.5 seconds, the size is small, the maintenance workload is less, and the adaptability is strong, making the ultrasonic equipment the first choice for the automated assembly line;
6. Dissimilar metal welding can be realized
Ultrasonic welding has excellent welding penetration and mixing effect for different types or similar metals (such as copper, copper or aluminum copper).
7. The welding process is convenient and easy
Ultrasonic metal welding machine processing ultrasonic welding does not require external factors such as flux, metal filler, external heating, etc. In most cases, the high frequency friction of ultrasonic welding makes it unnecessary to clean the surface of the workpiece.
Finally, the conductivity is good after welding, and the resistivity is extremely low or nearly zero. No sparks during welding, environmental protection and safety. These two are also the advantages of modern ultrasonic metal welding machines.
