Characteristics Of The Ultrasonic Metal Welding Process

May 13, 2026

1. Metal workpieces are overlapped and bonded into a solid form through the application of ultrasonic vibration and pressure; the welding time is brief, and the joint area remains free of structural defects (such as surface roughness).

2. Ultrasonic welding can be performed on either identical or dissimilar types of metals; it consumes less energy than electric welding, thereby offering greater economic efficiency.

3. Compared to other pressure-welding methods, ultrasonic metal welding requires significantly lower pressure-with pressure variations typically remaining under 10%-whereas cold-pressure welding can result in workpiece deformation ranging from 40% to 90%.

4. Ultrasonic metal welding minimizes thermal effects on the material (ensuring the temperature within the weld zone does not exceed 50% of the base metal's melting point), thereby preserving the original metallic structure; this makes it ideally suited for welding applications within the electronics industry.
