Welding characteristics and structures of same and different metal specimens using ultrasonic complex vibration welding equipments
Ultrasonic complex vibration welding of same and different metal specimens and structures of the welded area are studied using several complex vibration welding systems, scanning and transmission electron microscopes (SEM and TEM). Ultrasonic welding can weld various metal directly using vibration and static clamping pressure. The welding area is limited very narrow layer and can weld different...
متن کاملUltrasonic Complex Vibration Systems and Various Applications of High Power Ultrasonics
Ultrasonics complex vibrations with twoor three-dimensional vibration locus are effective for various applications. Various high-frequency and complex-vibration systems have been proposed and studied. The applications include ultrasonic direct welding of LSI, semiconductor chips without adhesive or solder, ultrasonic seam welding of thin metal plates, ultrasonic welding of thick metal specimens...
متن کاملInfluence of ultrasonic vibration on micro-extrusion.
Micro-forming is a miniaturization technology with great potential for high productivity. Some technical challenges, however, need to be addressed before micro-forming becomes a commercially viable manufacturing process. These challenges include severe tribological conditions, difficulty in achieving desired tolerances, and short tool-life due to inability of available die materials to withstan...
متن کاملUltrasonic Vibration Assisted Electro-Discharge Machining
An ultrasonic vibration has been superposed on the normal electrode movement to increase the flushing effect during a micro electro-discharge machining (EDM) process. A systematic study on the effects of ultrasonic vibration on the EDM performance for fabricating microholes in Nitinol has been completed. The introduction of ultrasonic vibration to the microEDM process has more than 60 times inc...
متن کاملAmplitude and Force Profiling: Studies in Ultrasonic Welding of Thermoplastics
This paper reviews effects of amplitude and force control during the ultrasonic welding cycle of thermoplastics. In a previously published paper, the benefits of amplitude profiling were detailed as increased strength and reduced part marking. This paper reviews the mechanisms for such observations and details additional benefits, such as decreased residual stresses and increased solvent resist...
