Tensile Strength of Cu Sheets Welded by Ultrasonic Metal Welding

Advanced Materials Research, 2013
This paper gives a description of an experimental study on the ultrasonic welding of metals. In ultrasonic metal welding, high frequency vibrations are combined with pressure to join two materials together quickly and securely, without generating large amount of heat. Horn, a key part of ultrasonic welding machine, should be designed very accurately to

Ultrasonic Welding of Refractory Metals

1961
Abstract : The effect of input power, clamping force, and duration of welding interval on the tensile-shear strength of ultrasonic welds in 0.005-in. Mo-0.5% Ti alloy sheet were studied and the results are tabulated. Exploratory tensile- shear measurements were made in 0.010-in.

Ultrasonically Welded Aluminium Foams/Sheet Metal – Joints

Advanced Engineering Materials, 2006
AbstractThe ultrasonic welding technology enables to produce high‐strength joints between sheet metal and aluminium foam sandwich (AFS) without melting of the metal or any damage of the foam structure. In the investigations the used welding processes and different factors influencing the weldability were varied. The achievable mechanical properties for

Ultrasonic Imaging of Welded Metals Using Simplified Ultrasonic Computerized Tomography

Japanese Journal of Applied Physics, 2002
In this paper, as a new measurement method to estimate the infinitesimal change of material condition, the simplified ultrasonic computerized tomography (CT) system, which uses the information of three directions, i.e., the 90°, +45° and -45° directions about the inspection plane, is proposed.

Ultrasonic Torsion Welding of Sheet Metals to Cellular Metallic Materials

Advanced Engineering Materials, 2003
AbstractOne of the most important requirements for finding new applications for cellular metals is to integrate them in complex technical structures. The metal foams have to be joined to each other, or to sheet materials, by suitable joining techniques.

Ultrasonic Torsional Welding of Metal/Glass Ceramics Joints

Key Engineering Materials, 2019
Ultrasonic welding is a suitable solid-state joining technique for producing high strength joints of similar or dissimilar materials, even of material combinations that were previously considered as not weldable. Several varieties of transmitting the ultrasound into the joining partners exist whereas the investigated torsional welding principle ...

Ultrasonic Welding of Polymer–Metal Hybrid Joints

2019
Joining of lightweight dissimilar materials becomes increasingly important, especially for structural applications and transportation industries to reduce the weight and thus decrease the fuel consumption and CO2 emissions. Previously, the joining of lightweight materials (metals and polymers) has been performed using mechanical fastenings, such as ...

Ultrasonic welding of ceramics/metals using inserts

Journal of Materials Processing Technology, 1998
Abstract This paper gives a description of an experimental study of the ultrasonic welding of ceramics and metals using inserts. Ultrasonic welding has made it possible to weld various ceramics such as Al 2 O 3 , SiC, Si 3 N 4 , AlN, to metals at room temperature, quickly and easily compared to other welding methods.
