20KHZ 2000W Digital Ultrasonic Metal Welding Machine For Welding Electrical Wire Splicing 

Characteristics of metal welding
It does not need flux and external heating, does not deform due to heating, has no residual stress, and does not require high pre welding treatment on the surface of weldment. Not only the same metals, but also dissimilar metals can be welded. Thin plates or wires can be welded to thick plates. The energy of ultrasonic welding good conductor is much less than that of current welding, which is often used in the welding of transistor or integrated circuit lead. When it is used for the seal welding of drugs and explosive materials, it can avoid the contamination of drugs due to dissolved objects in general welding, and it will not explode due to heating, etc.
Working principle and principle

Ultrasonic wave metal spot welder: it is similar to friction welding, but has some differences. The ultrasonic welding time is very short, and the temperature is lower than recrystallization. It is also different from pressure welding, because the static pressure is much smaller than pressure welding. It is generally believed that in the initial stage of ultrasonic welding process, the tangential vibration can remove the oxide on the metal surface, which is the process of repeated micro welding and damage of the protruding part of the rough surface, resulting in the increase of the contact area, the increase of the temperature of the welding area, and the plastic deformation at the interface of the weldment. In this way, under the action of contact pressure, when they are close to the distance where atomic gravity can act, the solder joint is formed. If the welding time is too long or the ultrasonic amplitude is too large, the welding strength will decrease or even damage. Ultrasonic metal welding machine is an advanced high-tech equipment which converts high-frequency electric energy into mechanical vibration energy through transducer and acts on the workpiece, generating high-frequency friction between the two workpiece surfaces until the two workpiece surfaces are heated and fused together. It can be widely used in the spot and strip welding of SCR chip lead, fast fuse melt seat, electrical lead terminal, Li ion, Ni MH, Ni Cd battery electrode lug, etc.

1. Ultrasonic metal welding machine is a new equipment which uses the friction principle of ultrasonic high-frequency vibration to transfer the energy of ultrasonic vibration into friction energy to the metal surface to be welded. Under the condition of heat generated by friction and pressure exerted on it, the metal structure molecules are fully activated to form the fusion between molecular layers.
2. Functional features:
Microcomputer control, electronic tuning frequency, LCD display, continuous adjustable power, simple operation, stable and reliable work; solid welding, good consistency, weldment with solid welding surface, high strength, beautiful, environmental protection and other characteristics. Easy to operate, built-in electronic protection circuit, safe to use, used for metal welding of the same kind, can implement single or multi-point welding for non-ferrous metals; widely used in battery and hardware industry.
