High Frequency Vibration 20Khz Ultrasonic Welding Wave Transmit to Metal Joint

Description:

Ultrasonic metal welding is a fast, clean and economical technology that is widely used in various automation industries.

The ultrasonic metal welding process is a process between cold press welding and friction welding that utilizes high density energy generated by high frequency mechanical vibration. The mechanical vibration of the welding head of the ultrasonic metal welding is parallel to the surface of the workpiece. During welding, the static pressure acts perpendicularly on the welding surface through the welding head, and at the same time superimposes the shearing force of the high-frequency vibration. When the shearing force exceeds the elastic limit of the material, the part of the contact surface of the workpiece begins to slip. This shearing force During the welding process, the direction is continuously changed at a frequency of tens of thousands of times per second, and the dirt on the surface of the workpiece is broken and removed. The surface of the pure metal begins to contact in multiple points. With the continuation of high-frequency vibration, the area of pure metal is continuously expanded. Until it expands into the entire weld zone, at the same time atom diffusion occurs on the contact surface, and the metal recrystallizes to form a fine grain structure and exhibits cold metal deformation characteristics.

Welding advantages:

Welding material does not melt, non-fragile metal properties

Good electrical conductivity after soldering, very low resistivity or near zero

Low requirements on the surface of the weld metal, oxidation or plating (lead, tin, zinc should be avoided) can be welded.

The soldering time is short and does not require any flux, gas or solder.

Welding without sparks, environmental protection and safety
