Ultrasonic welding joins प्लास्टिक using high-frequency ध्वनिक vibrations, typically between 15 kHz and 70 kHz. The vibrations are applied to parts clamped under दबाव, generating intense frictional heat at their interface. This localized heat rapidly melts the थर्माप्लास्टिक. Once the vibration ceases, the molten material solidifies under pressure, creating a strong, solid-state weld without the need for adhesives or fasteners.
