Numerical modeling of linear friction welding: a literature review

Linear friction welding (LFW) is a solid state process for joining metals together. While this process was developed originally for titanium alloys (e.g. blisks), over the past decade a number of materials were found to be weldable with LFW. In this review, the current status of understanding and development of LFW are presented. Particular emphasis has been given to the modeling of the LFW process. Finally, opportunities for further research and development of LFW are identified.
