Ultrasonic Welding of Metal/Composite Joints
Advanced Engineering Materials, 2004Ultrasonic metal welding joins load‐bearing glass fibres of composites or pure glass fibres directly to metal sheets. The weldings reach tensile shear strengths of up to 23 MPa. A possible application is given in the Figure which shows aluminium sheets welded to a composite (left) and a glass fibre fabric (right).

New methods of ultrasonic metal welding
1993 Proceedings IEEE Ultrasonics Symposium, 1993New methods of ultrasonic metal welding and characteristics of the welded specimens are studied. For welding of small specimens such as thin wire bonding, the bonding equipments designed using higher vibration frequency and complex vibration welding tips of 90, 120 and 190 kHz are significantly effective.

ULTRASONIC WELDING OF REFRACTORY METALS
1962Abstract : Preliminary conclusions regarding the weldability of 0.005-inch D-31 alloy foil are: (1) new D-31 possesses good ultrasonic weldability. Crackfree welds with good tensile-shear consistency can be made; (2) good ultrasonic welds can be attained over a consderable power range: 850 watts with the 0.25- inch spherical sonotrode-tip radius to ...

Ultrasonic welding of ceramic/metal
Journal of Materials Processing Technology, 1994Abstract This paper gives a description of an experimental study of the ultrasonic welding of ceramics and metals. Ultrasonic welding has made possible the welding of various ceramics, such as Al2O3, SiO2, ZrO2, SiC, and Si3N4, to aluminium and copper at the room temperature, both quickly and easily when compared to other welding methods. For example,

Ultrasonics, 1965
The ultrasonic welding of metals is now a well established technique. But the physical principles are still not clearly understood. In this paper, the author suggests that two physical mechanisms operate and that their effects can be distinguished in ultrasonically produced welds.

Investigation of monitoring methods for ultrasonic metal welding
Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2021, 2021Ultrasonic metal welding (UMW) is becoming a more broadly used technology for joining ductile materials, especially in the electric vehicle sector. The process, however, lacks monitoring capabilities that would improve confidence in the repeatability of welded joints. Often only destructive testing is used for quality evaluation.
