Disadvantages of ultrasonic metal welding equipment
1. Problems exist in the combination system
Ultrasonic metal welding technology in the welding process, it is necessary to realize the coordination of various cooperative systems to form a closely integrated overall system, which includes ultrasonic generator, acoustic system and mechanical system. If the coordination degree of the whole system is not consistent, it will lead to some problems in the stability, operability and reliability of the system.
2, welding machine manufacturing difficulties and insufficient understanding of its mechanism. Because ultrasonic metal welding technology can weld high density, high thickness of metal and dissimilar metal, so for the realization of this technology welding machine manufacturing requirements are higher. Compared with the traditional welding machine, the manufacturing process of ultrasonic metal welding machine is more difficult and higher cost, and because of many factors affecting the welding process parameters, it is not easy to understand and summarize the mechanism of welding machine.
3, the openness is poor and easy to high-frequency vibration
Ultrasonic metal welding equipment "openness" is poor, its extension size is strictly limited to the welding allowed range, and its joint form is still limited to lap joint, has not made further breakthroughs in technology. At the same time, ultrasonic metal welding machine in the process of welding joints prone to high-frequency vibration, may cause damage to the edge of the workpiece, especially hard and brittle materials.
4. Detection is difficult
For the current development of ultrasonic metal welding technology, it is difficult to detect the quality of welding products, and its matching testing equipment has not been popularized, and the detection method suitable for traditional welding technology can not be applied to the new technology. Detection technology can not keep up with mass production made certain difficulties.
