Friction Processes (Page 6)

Solid-state welding processes are a group of technologies in which joining is accomplished without melting the individual substrates. In these processes, bonding is accomplished by a combination of heating and forging. Heating is used to both lower the flow stresses enabling forging, as well as promote diffusion between the individual substrates. Common variations of these...

The U.S Department of Energy (DOE) Office of Fossil Energy (FE) and the National Energy Technology Laboratory (NETL) recently selected projects to receive cost-shared R&D under the opportunity announcement (FOA) DE-FOA-0002192, Extreme Environment Materials for Power Generation. One of the projects selected is Robust Dissimilar Metal Friction Welded Spool for Enhanced Capability for Steam Power...

Modeling of heat generation during plastic welding can save time and money in product development. EWI has developed an approach for spin welding, which shows good correlation to experimental results.  This work is described in FEA Modeling of Heat Development in Spin Welding, a paper by Miranda Marcus and Tom Feister. A similar approach can...
