Welding is an important joining method for the work with metals. During the welding process, the material is heated and deforms plastically which leads a change in microstructure in the heat affected zone, to complex residual stress distributions, and dist ...
In jewelry manufacturing, joining dissimilar materials is usually achieved by brazing or soldering, in which the materials comprising the joint are heated to a suitable temperature in the presence of a filler metal having a liquidus below the solidus of th ...
We attempted ultrasonic welding as a technique for the bonding of connectors to microfluidic devices. Different schemes of the method were explored based on different designs of the connectors to achieve a strong, minimal dead-volume connection. Results sh ...
The biomedical industry has an increasing demand for dissimilar metal joining processes, which are used for complex configuration designs, such as guidewires and other intravascular interventional devices. Their production becomes more and more challenging ...
The fabrication procedure changes when changing the size of the structural components. For the weldments, the change of the welding procedure leads to the change in residual stresses which consequently affects the fatigue life of the structure. The weld si ...
The biomedical industry shows increasing interest in the joining of dissimilar metals, especially with the aim of developing devices that combine different mechanical and corrosive properties. As an example, nickel titanium shape memory alloys joined to st ...
Since decades traditional friction welding methods are applied industrially to metal and thermoplastic synthetics. Research showed that for different applications this method is promising for wood too. The process does not necessitate any additional materi ...
A new laser micro-spot welding procedure for copper has been developed in order to eliminate the shortcomings of existing techniques based on laser pulse shaping or in-situ temperature control. This procedure consists in dividing the welding process in fou ...
At the Chair of Timber Constructions of the Swiss Federal Institute of Technology in Lausanne (EPFL) tests were carried out to join wooden work pieces by friction welding without any additional welding deposit. It could be determined that this kind of tech ...
For several decades friction welding technology has found broad application in many fields of the metal and plastic connection industry. The fabricated joints are laminar or punctiform depending upon the shape of the parts to be welded. The work presented ...
