Product Description

Ultrasonic metal welding oes not require the surface of the molten material to connect them. Instead, it applies high-frequency vibration to the two metal workpieces that need to be connected, which are placed between the "weld head" and the "anvil". The lower workpiece is "grabbed" by the toothed lines on the anvil and fixed in place. The frame drives the weld head to press the upper workpiece down until the upper and lower workpieces are in close contact and pressed. Then the welding head vibrates horizontally to generate vibration energy and remove surface contaminants and other coatings on the joint surface of the upper and lower workpieces. The friction generated by vibration will clear the unevenness of the joint surface, creating a clean, continuous welding area, allowing the atoms to cross the joint surface and spread freely to the other side. When the vibration stops, the free diffusion of this atom will recrystallize into a fine grain structure comparable to that of the cold-worked metal. The ent

Operational principle

The working principle of the 20K ultrasonic metal welding equipment relies on energy transfer and conversion through high-frequency mechanical vibrations:

1. Generation of high-frequency vibrations: The device converts electrical energy into high-frequency mechanical vibrations at 20 kHz (20,000 cycles per second) via a transducer, with the vibration amplitude amplified by a boom.

2. Combination of pressure and vibration: Under the clamping force of the welding fixture, the surface of the metal to be welded is subjected to a certain pressure, while high-frequency vibration generates intense friction at the contact surfaces.

3. Formation of solid-state bonding: The heat generated by friction causes the metal at the contact surfaces to enter a plastic state, disrupting the surface oxide layer. Under pressure, fresh metal atoms diffuse and fuse with each other, ultimately forming a robust solid-state bond (without requiring melted metal).

The entire process is rapid and efficient, eliminating issues such as thermal deformation and spatter associated with traditional welding, making it ideal for connecting precision metal components.
