Ultrasonic Wire Terminals Welding Machine
Because Ultrasonic wire terminals welding machine can generate high-frequency vibrations, we can use it to weld non-ferrous metals. Wire harness: The wire harness is a carrier that provides power or signals for a certain load source.
Because Ultrasonic wire terminals welding machine can generate high-frequency vibrations, we can use it to weld non-ferrous metals. Wire harness: The wire harness is a carrier that provides power or signals for a certain load source. It is widely distributed inside the device like blood vessels and neural networks, and transmits energy and control signals. It is generally believed that in the initial stage of the ultrasonic process of wire terminals welding machine , the tangential vibration removes the oxides on the metal surface, and causes the protruding parts of the rough surface to produce repeated micro-welding, deformation and damage to increase the contact area and increase the temperature of the welding zone. High, plastic deformation occurs at the interface of the weldment. Wire harnesses made of copper materials are the most widely used.

FAQ
Q: Why is ultrasound more suitable for welding power battery packs?
A: In order to meet the voltage and power output requirements of different types of automobiles, lithium-ion power batteries are often combined into power battery packs in various series and parallel modes; therefore, in the process of manufacturing power packs, it is necessary to combine multiple lithium-ion power battery poles. The ears (current collector) are connected. The connection of multiple lithium-ion power battery tabs can be riveted, bolted, and welded. Among them, the reliability of the riveted and bolted joints is insufficient, and they may become loose due to vibration, which may increase the internal resistance of the battery pack and cause safety problems such as thermal failure.
Q: How about the future development needs of Ultrasonic Wire Terminals Welding Machine?
A: From the earliest resistance welding machine, to the pulse energy storage welding machine, and then to the current automatic spot welding machine, including the double-sided spot welding machine.
Spot welding is relatively the earliest and most mature process. At present, most of the connection combinations of cylindrical batteries still use spot welding.
Spot welding requirements for batteries: clean surface, no stains, dust, etc., to avoid sparking, frying or false welding.
Requirements for welding materials: mostly metal nickel strips or nickel-plated steel strips are used for good welding effect. Generally, small cylindrical batteries use nickel strips with a thickness of 0.1~0.2mm. No matter how thick it is, it is easy to weld. Spot welding cannot weld aluminum foil, and the direct welding effect of copper strip is not good. High-power welding machine can be used to weld nickel-plated copper strip, but the effect is still not as good as that of nickel strip. The nickel sheet and the welding surface should be attached as firmly as possible, and the welding effect will be better.
