40kHz half wave welding head is a key component used in ultrasonic welding equipment. It is usually made of imported steel and undergoes heat treatment, with high hardness, strong stiffness, and high wear resistance.
The 40kHz half wave welding head is mainly used in electrode spot welding, aluminum to nickel battery technology, and other fields. Compared to some low-frequency welding heads, it produces lower noise during operation.
Its working principle is to use the high-frequency vibration of ultrasound to transfer the vibration energy to the joint of the workpiece to be welded. During the welding process, parameters such as the amplitude and frequency of the welding head play an important role.
In terms of amplitude, the working amplitude of a 40kHz half wave welding head is generally around 30 μ m, which needs to be adjusted according to specific welding materials and process requirements to achieve good welding results.
In terms of frequency, 40kHz is the designed working frequency, which can ensure that the welding head operates in a resonant state and works in coordination with the generator and other components.
In addition, the node position of the 40kHz half wave welding head is generally designed as fixed positioning, but it is not necessarily zero amplitude. In practical applications, the possible effects of this factor need to be considered, such as noise and partial energy loss. When using, it is necessary to select a suitable 40kHz half wave welding head according to the characteristics and welding requirements of the welded part, and cooperate with the corresponding ultrasonic welding equipment for operation.
