Ultrasonic Metal Spot Welder
The ultrasonic metal spot welder adopts a functional modular design and is flexible to use; the equipment has high welding accuracy and low temperature during welding.
Working principle：
1. The transducer converts the ultrasonic high-power oscillating signal into mechanical energy of the corresponding frequency, and applies it to the interface of the metal sheet to be welded, so that the joint of the metal sheet generates heat instantly, and then activates the particles in the metal lattice, so that the Molecules where the metal sheets meet are interpenetrated and welded together.
2. Ultrasonic Metal Spot Welder is a mechanical processing process, which converts high-frequency electric energy into mechanical vibration through the transducer device and acts on the workpiece, so that the surfaces of the workpieces in contact with each other generate high-frequency friction to generate heat and condense and weld. During the process, there is no current passing through the weldment, and no welding arc is generated in the electric welding mode. Since ultrasonic welding does not have problems such as heat conduction and resistivity, it is undoubtedly an ideal metal welding for non-ferrous materials. System, especially aluminum, nickel, copper, silver and other thin and thin materials for single-point, multi-point, square, strip, single-layer, multi-layer, composite welding has an ideal effect.

FAQ：
Q：The advantages of Ultrasonic Metal Spot Welder compared with traditional welding process
A：1. The welding time is very short, and the welding can be completed in an instant within 0.5 seconds;
2. The working temperature does not exceed its annealing temperature, so it does not change the metallographic structure of the working object;
3. Good conductivity after welding, and its resistivity is extremely low, nearly equal to zero;
4. There is sticky dirt or oxide on the metal surface, without surface treatment, it can be welded perfectly;
5. Almost all the workpieces can be welded without pretreatment, without soldering and soldering oil additives, which is economical and convenient;
6. The welding head and the smelting tool are made of wear-resistant materials and have long durability;
7. No sparks are generated during welding, the operator is safe and secure, there is no smoke smell, and it will not cause air pollution.
