The Ultrasonic Polar Ear Metal Spot Welding Machine is an advanced, high-efficiency welding system designed for precision joining of battery tabs (polar ears), electronic contacts, and thin metal sheets. Utilizing ultrasonic vibration technology, it delivers clean, fast, and reliable solid-state welds without melting the base material—ideal for lithium-ion batteries, supercapacitors, and delicate electronic assemblies.
Features
- The weld has low electrical resistance, ensuring excellent conductivity after welding. Its electrical resistance coefficient is close to zero.
- No marks of oxidation. The ultrasonic waves have a cleaning function. Even if there are contaminants or oxides on the metal surface, perfect welding can be achieved without cleaning the surface.
- All parts do not require pre-treatment, and welding can be accomplished without the addition of solder or flux, making it economical and convenient.
- The welding head is made of wear-resistant materials, ensuring long-lasting durability.
- The welds are firm, with the working temperature not exceeding the annealing temperature. It doesn’t alter the metal structure of workpieces. The welding strength is firmer than other methods. Also, the weld joints are neat and clean.
- Cost-effective welding, fast speed, easy operation, and convenient maintenance.
- The welding time is very short, generally completing the fusion in just 0.01-2 seconds.
- It doesn’t generate sparks during welding, ensuring safety. There is no smoke or odor, and it doesn’t cause air pollution.
