What are the necessary conditions for ultrasonic welding?
2025-10-10
The essential core of ultrasonic welding is the "energy - material - process" matching: The equipment provides stable high-frequency vibration energy, the material has the ability to undergo plastic deformation, and the process parameters (amplitude, pressure, time) precisely control the energy input. The combined action of these three factors enables the contact surface to achieve solid-state connection (for metals) or fusion (for plastics). In practical applications, parameter optimization through trial welding is required, especially for dissimilar materials or complex structure workpieces.
