Ultrasonic metal welder is used in the automotive and electronics industries to produce batteries, cable connections, copper wire welding etc. In metal welding, metals are welded in high temperatures, for instance.
Ultrasonic metal welding is mainly suitable for copper and aluminum connections. The process is fast and requires little ultrasonic energy.Components joined by ultrasonic metal welding equipment have high strength and excellent electrical conductivity, since the vibrations destroy oxide layers and remove impurities on metal surfaces. Contact resistances, such as those taking place during soldering or crimping do not occur. Reproducibility of the process sequences is important for precise and efficient production with a high degree of quality monitoring.
Ultrasonic welding offers numerous advantages over conventional metal welding:
Environmentally friendly: The weld process requires less energy compared to classic types of metal welding.
Precise: Ultrasonic welding is precise. This is important above all when welding very small metal parts, e.g. in batteries.
Gentle: Ultrasonic welding works without extremely hot temperatures. This ensures that the metals and other materials are not damaged.
Cost efficient: Ultrasonic welding is fast and does not require any additional tools such as solder.
Ultrasonic welding technology for nonferrous metals
In ultrasonic welding, it is mainly nonferrous metals such as aluminum, silver, copper and nickel which are used. Nonferrous metals are all pure metals apart from iron as well as alloys (compounds of various metals), which have an iron proportion of 50% of less. Pure ferrous metals are not used in ultrasonic welding.
Ultrasonic welding of aluminum and copper,Can aluminum be ultrasonically welded?
Ultrasonic Welding aluminum and copper is becoming ever more important, especially due to the constantly growing market for lithium-ion batteries. These are being used more and more as for power storage, especially in the electric car industry.
Aluminum and copper are primarily welded for cable and terminal connections in electronics and the automotive industry. A highly precise and reliable welding method is crucial here. Ultrasonic welding can do exactly that. And advantages include the short weld time, high energy efficiency and durability of the end products.
