Ultrasonic Spot Welding

What is ultrasonic handheld spot welding

The ultrasonic spot welder belongs to the category of ultrasonic welding, where two materials, metal or plastic, are welded together using high-frequency vibrations generated by ultrasound. For thermoformed parts without assembly contours or features where geometry and physical conditions preclude the possibility of standard welding operations, ultrasonic spot welding is relatively more suitable for processing.
